Tagged: tlc, SK Hynix, enterprise ssd, 72-layer tlc, 3d-v4, 3d nand
SK Hynix has revealed its new enterprise solid state drives based on 72-layer 512 Gb 3D TLC NAND flash dies paired with the company's own in-house controller and firmware. The SK Hynix eSSDs are available in a traditional SAS/SATA interfacing product with capacities up to 4TB and a PCI-E variant that comes in 'above 1TB." Both drive types are reportedly being sampled to datacenter customers in the US.
SK Hynix has managed to double the capacity and improve the read latency of its new 512 Gb 72-layer NAND flash over its previous 256 Gb 72-layer flash which debuted last year. The eSSD product reportedly hits sequential read and write speeds of 560 MB/s and 515 MB/s respectively. Interestingly, while random read IOPS hit 98,000, random write performance is significantly lower at 32,000 IOPS. SK Hynix did not go into details, but I suspect this has to do with the tuning they did to improve read latency and the nature of the 72-layer stacked TLC flash.
Moving up to the PCI-E interfacing eSSD, customers can expect greater than 1TB capacities (SK Hynix did not specify the maximum capacity they will offer) with sequential reads hitting up to 2,700 MB/s and sequential writes hitting 1,100 MB/s. The random performance is similar to the above eSSD with write performance being much lower than read performance at 230K read IOPS and 35K write IOPS maximum. The greatly limited write performance may be the result of the drive not having enough flash channels or the flash itself not being fast enough at writes which was a tradeoff SK Hynix had to make to hit the capacity targets with larger capacity 512 Gb (64 GB) dies.
Unfortunately, SK Hynix has not yet provided further details on its new eSSDs or the 3D-V4 TLC NAND it is using in the new drives. SK Hynix continuing to push into the enterprise storage market with its own SSDs is an interesting play that should encourage them push for advancements and production efficiencies to advance NAND flash technology.

Valve has announced support for AMD's TrueAudio Next technology in its Steam Audio SDK for developers. The partnership will allow game and VR application developers to reserve a portion of a GCN-based GPU's compute units for audio processing and increase the quality and quantity of audio sources as a result. AMD's OpenCL-based TrueAudio Next technology can run CPUs as well but it's strength is in the ability to run on a dedicated portion of the GPU to improve both frame times and audio quality since threads are not competing for the same GPU resources during complex scenes and the GPU can process complex audio scenes and convolutions much more efficiently than a CPU (especially as the number of sources and impulse responses increase) respectively.
Steam Audio's TrueAudio Next integration is being positioned as an option for developers and the answer to increasing the level of immersion in virtual reality games and applications. While TrueAudio Next is not using ray tracing for audio, it is physics-based and can be used to great effect to create realistic scenes with large numbers of direct and indirect audio sources, ambisonics, increased impulse response lengths, echoes, reflections, reverb, frequency equalization, and HRTF (Head Related Transfer Function) 3D audio. According to Valve indirect audio from multiple sources with convolution reverb is one of the most computationally intensive parts of Steam Audio, and TAN is able to handle it much more efficiently and accurately without affecting GPU frame times and freeing the CPU up for additional physics and AI tasks which it is much better at anyway. Convolution is a way of modeling and filtering audio to create effects such as echoes and reverb. In the case of indirect audio, Steam Audio uses ray tracing to generate an impulse response (it measures the distance and path audio would travel from source to listener) and then convolution is used to generate a reverb effect which, while very accurate, can be quite computationally intensive with it requiring hundreds of thousands of sound samples. Ambisonics further represent the directional nature of indirect sound which helps to improve positional audio and the immersion factor as sounds are more real-world modeled.
GPU versus CPU convolution (audio filtering) performance. Lower is better.
In addition to the ability of developers to dedicate a portion (up to 20 to 25%) of a GPU's compute units to audio processing, developers can enable/disable TrueAudio processing including the level of acoustic complexity and detail on a scene-by-scene basis. Currently it appears that Unity, FMOD Studio, and C API engines can hook into Steam Audio and the TrueAudio Next features, but it remains up to developers to use the features and integrate them into their games.
Note that GPU-based TrueAudio Next requires a GCN-based graphics card of the RX 470, RX 480, RX 570, RX 580, R9 Fury, R9 Fury X, Radeon Pro Duo, RX Vega 56, and RX Vega 64 variety in order to work, so that is a limiting factor in adoption much like the various hair and facial tech is for AMD and NVIDIA on the visual side of things where the question of is the target market large enough to encourage developers to put in the time and effort to enable X optional feature arises.
I do not pretend to be an audio engineer, nor do I play a GPU programmer on TV but more options are always good and I hope that developers take advantage of the resource reservation and GPU compute convolution algorithms of TrueAudio Next to further the immersion factor of audio as much as they have the visual side of things. As VR continues to become more relevant I think that developers will have to start putting more emphasis on accurate and detailed audio and that's a good thing for an aspect of gaming that has seemingly taken a backseat since Windows Vista.
What are your thoughts on the state of audio in gaming and Steam Audio's new TrueAudio Next integration?

Dell has released three new PowerEdge server models, all powered by one or two of AMD's new EPYC chips. The R6415 is a single socket, 1U server which supports 1TB of RAM, though The Register does point to a PR slide that implies 2TB might be achievable. The R7415 is larger at 2U because it can hold up to 12 SAS/SATA/NVMe + 12 NVMe drives or up to 14 3.5" drives. Last up is the dual socket R7425 with either 32 SATA/SAS drives or 24 NVMe flash drives and up to 4TB of RAM. Check out more specs at The Register.
"There are three PowerEdge AMD-powered servers: the R6415, R7415, and R7425. These accompany the PowerEdge 14G R640 and R740 Xeon SP servers in the Round Rock company's server portfolio, and they inherit general PowerEdge management and feature goodness."

Intel announced a major refresh of its Xeon D System on a Chip processors aimed at high density servers that bring the power of the datacenter as close to end user devices and sensors as possible to reduce TCO and application latency. The new Xeon D 2100-series SoCs are built on Intel’s 14nm process technology and feature the company’s new mesh architecture (gone are the days of the ring bus). According to Intel the new chips are squarely aimed at “edge computing” and offer up 2.9-times the network performance, 2.8-times the storage performance, and 1.6-times the compute performance of the previous generation Xeon D-1500 series.
Intel has managed to pack up to 18 Skylake-based processing cores, Quick Assist Technology co-processing (for things like hardware accelerated encryption/decryption), four DDR4 memory channels addressing up to 512 GB of DDR4 2666 MHz ECC RDIMMs, four Intel 10 Gigabit Ethernet controllers, 32 lanes of PCI-E 3.0, and 20 lanes of flexible high speed I/O that includes up to 14 lanes of SATA 3.0, four USB 3.0 ports, or 20 lanes of PCI-E. Of course, the SoCs support Intel’s Management Engine, hardware virtualization, HyperThreading, Turbo Boost 2.0, and AVX-512 instructions with 1 FMA (fuse-multiply-add) as well..
Suffice it to say, there is a lot going on here with these new chips which represent a big step up in capabilities (and TDPs) further bridging the gap between the Xeon E3 v5 family and Xeon E5 family and the new Xeon Scalable Processors. Xeon D is aimed at datacenters where power and space are limited and while the soldered SoCs are single socket (1P) setups, high density is achieved by filling racks with as many single processor Mini ITX boards as possible. Xeon D does not quite match the per-core clockspeeds of the “proper” Xeons but has significantly more cores than Xeon E3 and much lower TDPs and cost than Xeon E5. It’s many lower clocked and lower power cores excel at burstable tasks such as serving up websites where many threads may be generated and maintained for long periods of time but not need a lot of processing power and when new page requests do come in the cores are able to turbo boost to meet demand. For example, Facebook is using Xeon D processors to serve up its front end websites in its Yosemite OpenRack servers where each server rack holds 192 Xeon D 1540 SoCs (four Xeon D boards per 1U sleds) for 1,536 Broadwell cores. Other applications include edge routers, network security appliances, self-driving vehicles, and augmented reality processing clusters. The autonomous vehicles use case is perhaps the best example of just what the heck edge computing is. Rather than fighting the laws of physics to transfer sensor data back to a datacenter for processing to be sent back to the car to in time for it to safely act on the processed information, the idea of edge computing is to bring most of the processing, networking, and storage power as close as possible to both the input sensors and the device (and human) that relies on accurate and timely data to make decisions.
As far as specifications, Intel’s new Xeon D lineup includes 14 processor models broken up into three main categories. The Edge Server and Cloud SKUs include eight, twelve, and eighteen core options with TDPs ranging from 65W to 90W. Interestingly, the 18 core Xeon D does not feature the integrated 10 GbE networking the lower end models have though it supports higher DDR4 memory frequencies. The two remaining classes of Xeon D SoCs are “Network Edge and Storage” and “Integrated Intel Quick Assist Technology” SKUs. These are roughly similar with two eight core, one 12 core, and one 16 core processor (the former also has a quad core that isn’t present in the latter category) though there is a big differentiator in clockspeeds. It seems customers will have to choose between core clockspeeds or Quick Assist acceleration (up to 100 Gbps) as the chips that do have QAT are clocked much lower than the chips without the co-processor hardware which makes sense because they have similar TDPs so clocks needed to be sacrificed to maintain the same core count. Thanks to the updated architecture, Intel is encroaching a bit on the per-core clockspeeds of the Xeon E3 and Xeon E5s though when turbo boost comes into play the Xeon Ds can’t compete.
The flagship Xeon D 2191 offers up two more cores (four additional threads) versus the previous Broadwell-based flagship Xeon D 1577 as well as higher clockspeeds at 1.6 GHz base versus 1.3 GHz and 2.2 GHz turbo versus 2.1 GHz turbo. The Xeon D 2191 does lack the integrated networking though. Looking at the two 16 core refreshed Xeon Ds compared to the 16 core Xeon D 1577, Intel has managed to increase clocks significantly (up to 2.2 GHz base and 3.0 GHz boost versus 1.3 GHz base and 2.10 GHz boost), double the number of memory channels and network controllers, and increase the maximum amount of memory from 128 GB to 512 GB. All those increases did come at the cost of TDP though which went from 45W to 100W.
Xeon D has always been an interesting platform both for enthusiasts running VM labs and home servers and big data enterprise clients building and serving up the 'next big thing' built on the astonishing amounts of data people create and consume on a daily basis. (Intel estimates a single self driving car would generate as much as 4TB of data per day while the average person in 2020 will generate 1.5 GB of data per day and VR recordings such as NFL True View will generate up to 3TB a minute!) With Intel ramping up both the core count, per-core performance, and I/O the platform is starting to not only bridge the gap between single socket Xeon E3 and dual socket Xeon E5 but to claim a place of its own in the fast-growing server market.
I am looking forward to seeing how Intel's partners and the enthusiast community take advantage of the new chips and what new projects they will enable. It is also going to be interesting to see the responses from AMD (e.g. Snowy Owl and to a lesser extent Great Horned Owl at the low and niche ends as it has fewer CPU cores but a built in GPU) and the various ARM partners (Qualcomm Centriq, X-Gene, Ampere, ect.*) as they vie for this growth market space with higher powered SoC options in 2018 and beyond.

- Intel Xeon Scalable Processor Launch - New Architecture, New Platform for Data Center
- Qualcomm Centriq 2400 Arm-based Server Processor Begins Commercial Shipment

Intel recently showed off a prototype of their Vaunt smart glasses, which have a significant advantage over Google's failed Glass, no visible camera. Instead these glasses fire a laser into your eyeholes, something you usually are told to avoid but in this case should be perfectly safe. The laser projects small monochrome images or text at the bottom of your field of vision, which does not interfere with your line of sight and is mostly invisible until you look down. So far the amount of information able to be displayed is limited on the prototype and it is a long way off of hitting the market so you should expect changes. If you have some sort of minor vision problem, The Inquirer assures us that you will still be able to see the information the Vaunt displays.
"Instead, the Vaunt glasses use a low-powered class one laser to project a monochrome 400x150 resolution image on to the retina of your eye. Yeah, if you find eyes queasy you might want to get yourself a cup of tea."

Microsoft is introducing lower-end versions of its Surface Book 2 and Surface Laptop thin and lights in a very good news/bad news way. The good news is that customers will not have to give up much in the way of specifications, but the bad news being that these new SKUs are not much cheaper than their predecessors as a result. If you were hoping for a budget Surface Book, this is not the device you are looking for.
Tech Report reports that Microsoft is now offering a Surface Book 2 with the same Core i5 7300U (dual core with Hyperthreading) and 8GB base RAM as the exiting i5 model, but with half the storage at 128 GB. All other specifications remain the same including the 13.5” 3000x2000 resolution display, 23mm thick chassis with 2-in-1 folding hinge, and the same USB 3.1 Gen 1, headphone, SD card, and Surface Dock I/O ports. The new “budget” model starts at $1,199 which is $300 cheaper than the i5 7300U model with 256 GB storage. Not bad considering you are only giving up storage space but still priced at a premium.
In addition to the Surface Book 2, Microsoft is also adding a cheaper Surface Laptop which cuts the cost to entry to $799. Customers will have to settle for the silver version however, as that is currently the only color option at that price point. Performance as well as storage take a hit on this cost-cutting endeavor as well with the previous Core i5 base CPU (2c/4t up to 3.1 GHz) replaced with a Core m3-7Y30 (2c/4t up to 2.6 GHz). The new budget model further includes 4GB of RAM and 128 GB of internal storage. Fortunately, the 13.5” 2256x1504 touchscreen display remains the same. The price difference between the Core m3 SKU and the previously base Core i5 7200U SKU is only $200 and you are giving up more than storage this time to get there.
It appears the Surface Laptop still comes with Windows 10 S while the Surface Book 2 comes with Windows 10 Pro. Microsoft provides 1-year warranties on these machines.
Are the new lower-cost versions enough to get you to buy into the Surface and Windows 10 ecosystem?

Plextor is introducing a new SATA SSD option with its 2.5” M8VC and M.2 M8VG solid state drives. The M8V series pairs a Silicon Motion SM2258 controller with Toshiba’s 64-layer 3D TLC NAND (BICS flash) to deliver budget SSDs in 128 GB, 256 GB, and 512 GB capacities. Plextor is using its own Plex Nitro firmware and includes SLC cache, system RAM cache support, Plex Compressor compression, 128-bit ECC and LDPC error correction, and hardware AES encryption. Plextor warranties its M8V series SSDs for three years.
Plextor’s new drives are limited by the SATA 6 Gbps interface and max out at 560 MB/s sequential reads. Sequential writes top out at 400 MB/s for the 128 GB model, 510 MB/s for the 256 GB model, and 520 MB/s for the 512 GB drive. Similarly, 4K random reads and 4K random writes scale up as you add more flash which is shown in the table below. The top-end 512 GB drive hits 82K 4K random read IOPS and 81K 4K random write IOPS. The 256 GB solid state drives are only slightly slower at 81K and 80K respectively. The 128 GB M8V SSDs do not appear to have enough flash channels to keep up with the larger capacity drives though as their performance maxes out at 60K random reads and 70K random writes.
|Plextor M8V Series||128 GB||256 GB||512 GB|
|Sequential Reads||560 MB/s||560 MB/s||560 MB/s|
|Sequential Writes||400 MB/s||510 MB/s||520 MB/s|
|4K Random Read IOPS||60K||81K||82K|
|4K Random Write IOPS||70K||80K||81K|
|Endurance||70 TBW||140 TBW||280 TBW|
|MTBF (hours)||1.5 Million||1.5 Million||1.5 Million|
Plextor rates the M8V series at 0.5 DWPD (drive writes per day) and write endurance of 70 TB for the 128 GB, 140 TB for the 256 GB, and 280 TB for the 512 GB model. Plextor rates them at 1.5 million hours MTBF. These numbers aren’t too bad considering this is TLC flash and they are likely to get more life than the ratings (it’s just not guaranteed).
The SM2258 controller appears to be fairly well established and has also been used by Adata, Mushkin, and others for their budget solid state drives. Plextor did not announced pricing or availability and in searching around online I was not able to find them for sale yet. Its previous S2C series (M7V replacement) SATA drives came in at just under 26 cents/gigabyte using the same SMI 2258 controller but with SK Hynix 16nm planar TLC flash though so I would expect the M8V to come in close to that if not better.
I just wish we could get a SATA 4 standard already to at least get consumer systems up to the 12 Gbps enterprise-oriented SAS can hit. While RAM and GPU shopping may make your wallet cry more than a Steam sale, at least it is a good time to be shopping for storage. What do you think about the influx of budget SSDs? Have you upgraded your family’s PCs to the magical performance of solid state storage yet?

Tagged: final fantasy xv, round up
The new iteration of Final Fantasy sports some hefty recommendations, including the need for a Core i7-3770 or FX-8350 powering your system. TechSpot decided to test out a variety of CPUs to see how they performed in tandem with a GTX 1080 Ti. With 14 CPUs represented, including several generations of Intel chips and a representative from each of the three Ryzen lines they proceeded to run through a battery of benchmarks. The tests quickly showed that if you are running a quad core CPU clocked lower than 4GHz, from either vendor, you are not going to have a good time. Check out the full results to see if your system can handle it or if you should be shopping for a Ryzen 5 or 7, or perhaps a higher end Coffee Lake if Intel is your cup of tea.
"Today we're checking out Final Fantasy XV CPU performance using the new standalone benchmark released ahead of next month's PC launch. The reason we want to look at CPU performance first is because the game is extremely CPU intensive, far more so than we were expecting."

The only difference between the Core 21 and View 21 is the front panel, the Core G21 sports a matte grill while the View 21 offers a smoky glass front panel. This makes it somewhat easier for [H]ard|OCP to review both cases at once. They both offer extensive cooling options, the front can house your choice of to two 140mm fans, three 120mm fans, or a radiator between 120mm to 360mm in size. The top of the case can support a 120 or 140mm fan, the bottom another 120mm fan in addition to having an intake for your PSU, neither can support a radiator, however the rear can accommodate a 120mm fan or rad. $70 is a decent price for a case sporting tempered glass, however [H] did feel Thermaltake should have included more than just a single fan in the package. Get the full details here.
"This is a two-for-one review: Thermaltake's Core 21 and View 21 Tempered Glass Edition cases are identical aside from the front panel.

Microsoft is changing how they will distribute Windows S, their Chrome-like locked down OS. It will now become an option on all Windows 10 installations, allowing you to enable it if you feel the need to set up a computer which can only run apps from the Microsoft Store and only surf via Edge. The Inquirer cites an interesting fact, 83% of users who do not disable Windows S mode in the first week remain with that OS permanently. Perhaps they don't know any better, or perhaps they were one of those who were satisfied with the original Surface's Windows RT?
"Now, the company has confirmed that it will instead offer an "S Mode" on standard versions of Windows 10 instead, locking the machine down to a walled garden of apps from the Microsoft Store, and blocking traditional Win32 programs. And, of course, restricting you to using bloody Edge browser. "

MSI is updating its Radeon RX 580 Armor series with a new MK2 variant (in both standard and OC editions) that features an updated cooler with red and black color scheme and a metal backplate along with Torx 2.0 fans.
The graphics card is powered by a single 8-pin PCI-E power connection and has two DisplayPort, two HDMI, and one DVI display output. MSI claims the MK2 cards use its Military Class 4 hardware including high end solid capacitors. The large heatsink features three copper heatpipes and a large aluminum fin stack. It appears that the cards are using the same PCB as the original Armor series but it is not clear from MSI’s site if they have dome anything different to the power delivery.
The RX 580 Polaris GPU is running at a slight factory overclock out of the box with a boost clock of up to 1353 MHz (reference is 1340) for the standard edition and at up to 1366 MHz for the RX 580 Armor MK2 OC Edition. The OC edition can further clock up to 1380 MHz when run in OC mode using the company’s software utility (enthusiasts can attempt to go beyond that but MSi makes no guarantees). Both cards come with 8GB of GDDR5 memory clocked at the reference 8GHz.
MSI did not release pricing or availability but expect them to be difficult to find and for well above MSRP when they are in stock If you have a physical Microcenter near you, it might be worth watching for one of these cards there to have a chance of getting one closer to MSRP.

External storage does not have to be slow, as the OWC Mercury Helios 3 PCIe Thunderbolt 3 external drive demonstrates. The TB3 connection is capable of up to 40Gbps, assuming you have the proper connection, which will keep a drive such as the the Kingston DC1000 NVMe SSD very busy. In The SSD Reviews testing, they saw the data transfer cap out at 2.8GB/s read and between 2.5-2.7GB/s write, which makes this perfect for HD video or for manipulating large media files. The enclosure will set you back about $200, the cost of the PCIe SSD you put inside it is a choice for you to make.

For the next little while at least, you should be able to pay off the purchase of a Threadripper 1950X by mining with it. [H]ard|OCP did some testing using Monero and found that Threadripper is quite efficient at mining. When mining full tilt the system, including a GTX 1080, used only 335W which could keep your energy bill somewhat lower than alternative systems. Of course, with Bitcoin's value wobbling drunkenly might want to move quickly ... or skip it altogether.
"If you could have your AMD Ryzen Threadripper pay for itself over time, would you? No matter your feelings towards cryptocurrency mining, you can get your Threadripper mining today, and paying for itself. The process could not be much easier either. The big kicker is the actual wattage load on your system is likely much less than you would guess."

Tagged: VR, virtual reality, Tobii, htc vive, eye tracking, CES 2018, CES
Last month in Tobii's suite at CES I was given a demonstration of a prototype VR headset that looked like any other HTC Vive - except for the ring of Tobii eye-tracking sensors inside and around each lens. While this might seem like a bit of an odd concept at first I was patient as the benefits were explained to me, and then blown away when I actually tried it myself.
As you know, if you have used a VR headset like the Oculus Rift or HTC Vive, the basic mechanics of VR interaction involve pointing your head in the direction you want to look, reaching with your hand (and controller) to point to an object, and then pressing a button on the controller to act. I will be completely honest here: I don't like it. After a little while the fatigue and general unnatural feeling of rapid, bird-like head movements kills whatever enthusiasm I might have for the experience, and I was the last person to give high praise to a new VR product. HOWEVER, I will attempt to explain why simply adding eye tracking actually made the entire experience 1000 times better (for me, anyway).
When I put on the prototype headset, the only setup I had to do was quickly follow a dot in my field of vision as it moved up/down/left/right, like a vision test for a driver's license. That's the entire calibration process, and with that out of the way I was suddenly able to look around without moving my head, which made the head movements when they followed feel completely natural. I would instinctively look up, or to the side, with my head following when I decided to focus attention on that area. The amount of physical head movements was reduced to normal, human levels, which alone prevented me from feeling sick after a few minutes. Of course, this was not the only demonstrated feature of the integrated eye-tracking, and if you are familiar with Tobii you will know what's next.
This looks primitive, but it was an effective demo of the eye-tracking integration
The ability of the headset to know exactly where you are looking allows you to aim based on your line of sight if the game implements it, and I tried some target practice (throwing rocks at glass bottles in the demo world) and it felt completely natural. After launching a few rocks at distant bottles I instantly decided that this should be the mechanic of fantastic VR football video game - that I could throw at different receivers just by looking them down.
I also received a demo of simulated AR integration (still within the VR world), and a demo of what eye-tracking adds to a home theater experience - and it was pretty convincing. I could scroll around and select movie titles from an interface by simply looking around, and within the VR world it was as if I was looking up at a big projection screen. Throughout the different demos I kept thinking about how much more natural everything felt when I wasn't constantly moving my head around and pointing at things with my controller.
Finally, there was another side to everything I experienced - and it might have been the most interesting thing from a PC enthusiast perspective: if the VR headset can track your focus, the GPU doesn't have to render anything else at full resolution. That alone could make this something of a breakthrough addition to the current VR headset space, as performance is very expensive (even before the mining craze) and absolutely necessary for a smooth, high frame-rate experience. After 45 minutes with the headset on, I felt totally fine - and that was a change.
So what is the takeaway from all this? I'm just an editor who had a meeting with Tobii at CES, and I walked out of the meeting with a couple of business cards and nothing else. I admit that I am a VR skeptic who went into the meeting with no expectations. And I still left thinking it was the best product I saw at the show.
More information and media about the CES demos are available from Tobii on their CES blog post.

Have you experienced the sheer frustration of explaining to a friend or family member that the reason their machine slowed down somewhat and is generating popups at a fearsome rate is because of the crapware they downloaded and not your ministrations? Convincing someone who installed a registry cleaner or supposed driver update tool that that software is the root of their suffering can be as profitable as arguing with a brick wall that it is mostly empty space and thus you should be able to walk through it; in other words an exercise in futility. Come March, Windows Defender will remove many of the more questionable ones automatically, though The Inquirer suggests some of the more innocuous ones may remain.
"We've all been there - warnings of out of date drivers, thousands of registry errors, and usually with a message claiming "we'll fix 30 for free, then you pay". Most of it is utter twaddle and won't affect your computing experience at all. In fact, in a lot of cases, they do more harm than good."

Tagged: Seagate, quarterly earnings, Hard Drive, financial results, enterprise
Seagate Technology has announced its quarterly earnings for the second quarter of fiscal year 2018 (the quarter ending 12/29/2017). The Cupertino-based company has reported quarterly revenue of $2.9 billion, net income of $159 million, and diluted EPS of 55 cents. On a Non-GAAP reporting basis, Seagate saw Q2 FY2018 net income of $431 million and earnings per share of $1.48.
Seagate's revenue remained flat year-over-year, but increased 11.5% versus the previous quarter. Net income decreased 12% QOQ and 46% YoY using GAAP accounting methods, but on a non-GAAP basis Seagate reports a 54% increase versus the previous quarter and 4.6% increase versus the same quarter last year so it's not all bad news. The company is also managed to amass quite a bit of cash including $850 million from operations and $773 of free cash flow.
|Q2 FY2018||Q1 FY2018||Q2 FY2017||QOQ||YoY|
|Revenue||$2.9 billion||$2.6 billion||$2.9 billion||+11.5%||=|
|Net Income (GAAP)||$159 million||$181 million||$297 million||-12%||-46%|
|Diluted Earnings Per Share (GAAP)||0.55||0.62||1.00||-11.5%||-45%|
|Net Income (Non-GAAP)||$431 million||$279 million||$412 million||+54%||+4.6%|
|Diluted EPS (Non-GAAP)||1.48||0.96||1.38||+54%||+7.2%|
Seagate manufactures both mechanical hard drives and solid state drives, and while the company cranks out many internal and external drives for consumers, the company is very much focused on the enterprise market, especially where its solid state storage is concerned. Seagate states in its press release that it is heavily focused on cloud storage with its 60TB 3.5" SAS drive and NVMe add-in-card (which it demonstrated at FMS 2016). The company has partnered with Facebook to build its 1U Lightning storage solution (up to 120TB of flash storage using 60 2TB M.2 NVMe drives) and continues to target the enterprise and exascale/HPC markets with their absolutely massive and ever-growing data demands for big data analytics of financial and user data, uploaded and user-generated media, cloud backup, and research/simulation data for supercomputers. Further, the company continues to push mechanical enterprise storage to ever higher capacities with Barracuda Pro and also has its Ironwolf NAS and sequential-optimized Skyhawk drives for surveillance systems. On the flash storage front, Seagate has its Nytro M.2 NVMe and Nytro SAS SSDs.

I am interested to see where Seagate (STX) will go with its flash storage (Will they ever bring it to the consumer market in a big way? They do have a few products, but their focus seems to be mostly on enterprise.) and if they will manage to match or surpass Western Digital and Toshiba this year in the enterprise HDD capacity war. Currently, the company's Barracuda, IronWolf, and Exos drives top out at 12TB including the second generation Helium-sealed versions.

Tagged: simply nuc, nuc, Dawson Canyon, 8th generation core, Intel, fanless, SFF
Intel partner Simply NUC has announced its new commercial NUC lineup powered by Kaby Lake R vPro processors. The lineup includes the NUC7i7DNKE thin chassis, NUC7i7DNHE with tall chassis and 2.5" drive support, the board-only NUC7i7DNBE, and NUC7i7DNFE which features a fanless design.
The company's new Dawson Canyon NUCs are all based on the same 4" x 4" motherboard platform and the Intel Core i7 8650U vPro processor. Save for the taller model, the small form factor PCs share the same external I/O including four USB 3.0 ports, two HDMI 2.0 (4k@60Hz) video outputs, and an Intel-powered Gigabit Ethernet port. Specifically, networking is handled by an Intel i219-LM Ethernet controller and Intel 8265 802.11ac wireless (2x2 at up to 867 Mbps) + Bluetooth 4.2. The wireless module comes pre-installed in all except the board only SKU where it is optional. At a minimum the Simply NUC PCs (except board only) come with a 4GB SODIMM for RAM and a 128GB M.2 SATA solid state drive. Before OS or any other upgrades, the NUC with active cooling chassis systems start at 709.95. Pricing for the board only NUC7i7DNBE and fanless NUC7i7DNFE has not yet been released but I would expect the board only SKU to go for around $550 and the fanless model to come in around $750.
Users can add their own hardware or configure them from Simply NUC with up to 32 GB of RAM, 2TB of NVMe PCI-E storage (for a more than pretty penny!), and an additional 2TB of 2.5" SATA hard drive storage on the NUC7i7DNHE model.
The Core i7 8650U used in these Dawson Canyon NUCs is a quad core Kaby Lake R processor with a 15W TDP that runs at a base clockspeed of 1.9 GHz and can boost to up to 4.2 GHz. It supports Intel's vPro and AMT management technologies, has 8MB of cache, and features Intel UHD Graphics 620 running at up to 1.15 GHz.
The Dawson Canyon NUCs are available for pre-order now and are expected to ship as soon as March 2018 (though the Simply NUC website lists April 6th at time of publication). I am interested to see the fan-less model, but these machines seem very much targeted at the business and industrial markets rather than home PCs so expect to pay a premium for the small form factor if you are interested in them.

Tagged: z-ssd, Z-NAND, Samsung, HPC, enterprise, ai
Samsung will be introducing a new high performance solid state drive using new Z-NAND flash at ISSCC next month. The new Samsung SZ985 Z-SSD is aimed squarely at the high-performance computing (HPC) market for big data number crunching, supercomputing, AI research, and IoT application development. The new drive will come in two capacities at 800GB and 240GB and combines low latency Z-NAND flash with 1.5GB LPDDR4 DRAM cache and an unspecified "high performance" Samsung controller.
The Z-NAND drive is interesting because it represents an extremely fast storage solution that offers up to 10-times cell read performance and 5-times less write latency than 3-bit V-NAND based drives such as Samsung's own PM963 NVMe SSD. The Z-NAND technology represents a middle ground (though closer to Optane than not) between NAND and X Point flash memory without the expense and complexity of 3D XPoint (at least, in theory). The single port 4-lane drive (PCI-E x4) reportedly is able to hit random read performance of 750,000 IOPS and random write performance of 170,000 IOPS. The drive is able to do this with very little latency at around 16µs (microseconds). To put that in perspective, a traditional NVMe SSD can exhibit write latencies of around 90+ microseconds while Optane sits at around half the latency of Z-NAND (~8-10µs). You can find a comparison chart of latency percentiles of various storage technologies here. While the press release did not go into transfer speeds or read latencies, Samsung talked about that late last year when it revealed the drive's existence. The SZ985 Z-SSD maxes out its x4 interface at 3.2 GB/s for both sequential reads and sequential writes. Further, read latencies are rated at between 12µs and 20µs. At the time Allyn noted that the 30 drive writes per day (DWPD) matched that of Intel's P4800X and stated that it was an impressive feat considering Samsung is essentially running its V-NAND flash in a different mode with Z-NAND. Looking at the specs, the Samsung SZ985 Z-SSD has the same 2 million hours MTBF but is actually rated higher for endurance at 42 Petabytes over five years (versus 41 PB). Both drives appear to offer the same 5-year warranty though we may have to wait for the ISSCC announcement for confirmation on that.
It appears that the SZ-985 offers a bit more capacity, higher random read IOPS, and better sequential performance but with slightly more latency and lower random write IOPS than the 3D XPoint based Intel Optane P4800X drive.
In all Samsung has an interesting drive and if they can price it right I can see them selling a ton of these drives to the enterprise market for big data analytics tasks as well as a high-speed drive for researchers. I am looking forward to more information being released about the Z-SSD and its Z-NAND flash technology at the ISSCC (International Solid-State Circuits Conference) in mid-February.
