Tagged: western digital, wdc, OS3, My Cloud Mirror
A little over a year ago, we took a look at the Western Digital My Cloud Mirror. This was a simple network connected storage device that came with a suite of software and mobile apps to give remote access to the data stored at home.
Today Western Digital announced a refresh to the My Cloud Mirror. Available for pre-order today and in stores at the end of this month, the new Mirror is essentially just a speed boosted version of the original version (which was no slouch really). Something the added speed may help with is the functionality being added to WD's My Cloud OS software:
The new 'OS3' version adds some requested features, such as using the My Cloud as a hub for syncing across multiple systems (similar to Dropbox, but with your own storage being used instead of their servers).
Another requested feature was the ability to backup and/or offload pictures and videos from mobile devices. This can be done only when connected to WiFi or over cellular data if the user has the GB/month to spare on their data plan.
Another interesting feature is My Cloud Albums. This feature lets you invite your friends/family to share *their* photos / videos from an event. You send them a link and they can then upload their content directly to your My Cloud via their mobile browser or via the My Cloud app (if they have it installed). This sounds like a great idea for collecting photos taken at group events like birthday parties or weddings.
My Cloud OS3 is slated for a 21 September release. We will take a look another look at its features once released.
Western Digital's full press blast appears after the break.

Tagged: sandisk, Ultra II, Marvell 88SS9189, Marvell 88SS9190
We've seen Sandisk's Ultra series before but the Ultra II is relatively new to the market. If anything, they have made the pricing even more attractive, the top end 960GB model is a mere $310, $0.32/GB is getting closer to Ryan's preferred SSD pricing. As far as the advertised speeds, sequential read and write remain constant at 550MB/s and 500MB/s but IOPS vary by the size of the drive from 81K/80K random read/write for the 120GB model to 99K/83K for the 960GB model. [H]ard|OCP's testing shows performance more or less in line with the OCZ Trion 100 but somewhat slower than the Samsung 850 EVO, both of which are almost the exact same price. Check out the full review to see the exact differences, or simply rejoice in the fact that SSDs are approaching prices below $0.30/GB.
"Most of you know that the easiest way to get a performance boost from your old mechanical hard drive is to get rid of it and replace it with a shiny new SSD. SanDisk's Ultra II offers a lot of capacity for the money and comes with a 3 year warranty. Is that enough to compete in a market where prices are falling across every category?"

While roaming around at IDF, Ryan spotted a couple of new OCZ parts that were strangely absent from Flash Memory Summit:
You are looking at what is basically a Toshiba NVMe PCIe controller and flash, tuned for consumer applications and packaged/branded by OCZ. The only specific we know about it is that the scheduled release is in the November time frame. No specifics on performance yet but it should easily surpass any SATA SSD, but might fall short of the quad-controller-RAID RevoDrive 350 in sequentials.
As far as NVMe PCIe SSDs go, I'm happy to see more and more appearing on the market from every possible direction. It can only mean good things as it will push motherboard makers to perfect their UEFI boot compatibility sooner rather than later.
More to come on the RevoDrive 400 as November is just around the corner!

**Edit** There was some speculation about which controller was in this SSD. It has since been solved. Here's a shot of the top of the PCB:
Now lets compare that with a shot I caught at FMS 2015 last week:
...from the Phison booth. I hadn't wirtten up my Phison post yet but this new Kingston SSD is most certainly going to be using the Phison E7 controller. Here's the placard stating some high level specs:
We saw a draft copy of Kingston’s HyperX Predator at CES 2014. That demo unit was equipped with a SandForce 3700 series controller, but since SandForce never came through on that part, Kingston had to switch gears and introduce the HyperX Predator with a Marvell 88SS9293 controller. The Marvell part was very capable, and the HyperX Predator turned out to be an attractive and performant PCIe SSD. The one catch was that Marvell’s controller was only an AHCI part, while newer NVMe-based SSDs were quickly pushing the Predator down in our performance results.
Kingston’s solution is a newer generation PCIe SSD, this time equipped with NVMe:
We have very little additional information about this new part, though we can tell from the above image that the flash was provided by Toshiba (toggle mode). They also had Iometer running:
We were not sure of the exact workload being run, but those results are in line with the specs we saw listed on Silicon Motion’s SM2260, seen last week at Flash Memory Summit.
We’ll keep track of the development of this new part and hope to see it in a more disclosed form at CES 2016. Kingston's IDF 2015 press blast appears after the break.

Tagged: XPoint, ssd, Optane, Intel, IDF 2015
Just three weeks ago, we reported 3D XPoint Technology. This was a 2-layer stack of non-volatile memory that couples the data retention of NAND flash memory with speeds much closer to that of DRAM.
The big question at that time was less about the tech and more about its practical applications. Ryan is out covering IDF, and he just saw the first publically announced application by Intel:
Intel Optane Technology is Intel’s term for how they are going to incorporate XPoint memory dies into the devices we use today. They intend to start with datacenter storage and work their way down to ultrabooks, which means that XPoint must come in at a cost/GB closer to NAND than to DRAM. For those asking specific performance figures after our earlier announcement, here are a couple of performance comparisons between an SSD DC P3700 and a prototype SSD using XPoint:
At QD=8, the XPoint equipped prototype comes in at 5x the performance of the P3700. The bigger question is how about QD=1 performance, as XPoint is supposed to be far less latent than NAND?
Yes, you read that correctly, that’s 76k IOPS at QD=1. That means only issuing the SSD one command at a time, waiting for a reply, and only then issuing another command. Basically the worst case for SSD performance, as no commands are stacked up in the queue to enable parallelism to kick in and increase overall throughput. For comparison, SATA SSDs have a hard time maintaining that figure at their maximum queue depths of 32.
Exciting to see a follow-on announcement so quickly after the announcement of the technology itself, but remember that Intel did state ‘2016’ for these to start appearing, so don’t put off that SSD 750 purchase just yet.

It's been a while since Western Digital updated their Black series of HDDs, with their 4TB release taking place over two years ago. I'm happy to say that for those looking for a massive HDD suited for holding that enormous games folder too large to fit on your SSD, your wait is finally over, as today WD has updated the Black line to include 5TB and 6TB capacity units.
The Black series introduced that nifty dual stage actuator technology nearly five years ago, and has added a few more bells and whistles along the way. These new models include a 128MB cache and run on dual-core processors.
Along with that news also comes an update to their Red Pro series, which was also limited to 4TB in capacity when they launched last year. Red Pro models will now also include 5TB and 6TB units, so those wanting the most performance and lowest response time from their NAS can now also enjoy that performance at a 50% gain in capacity.
The new 6TB Red Pro also includes a 128MB cache and can peak at 214MB/sec (at the start of the disk). Also included in these is WD's NASware 3.0 firmware, which is specifically tuned to enable packs of these operating in packs while minimizing the effects of vibration on performance.
The 5TB Black comes in at $264 while the 6TB comes in at $294. The Red Pro's come at only an additional $5 over the Black, respectively (small price to pay for better compatibility with larger arrays). Both the Red Pro and Black carry a 5-year warranty.

We’ve reviewed a few Silicon Motion SSDs in the past (Angelbird | Corsair Force LX | Crucial BX100), and I have always been impressed with their advances in SSD controller technology. Their SM2246EN SATA controller was launched two years ago, and strived to be a very efficient and performant unit. Based on our reviews that turned out to be true, and this allowed Silicon Motion to slide into the void left by SandForce, who repeatedly delayed their newer developments and forced the many companies who were sourcing their parts to look elsewhere.
The many SSDs using Silicon Motion’s SM2246EN controller.
Silicon motion pushed this further with their SM2256, which we first saw at the 2014 Flash Memory Summit and later saw driving SLC/TLC hybrid flash at this past Consumer Electronics Show. While the SM2256 makes its way into more and more products, I was glad to see an important addition to their lineup at this year’s FMS:
Finally we see Silicon Motion doing a PCIe controller! This is the SM2260, seen here in the M.2 form factor…
…and here in SATA Express. While the latter will likely not be as popular due to the more limited PCIe lanes present in SATA Express, I’m sure we will see this controller appearing in many PCIe devices very soon. The stated performance figures may be a bit shy of currently comparing SSDs like the Intel SSD 750 and Samsung SM951, but with the recent introduction of Z170 motherboards and RST PCIe RAID, it is now easier to RAID a smaller capacity pair of these devices, increasing the performance of slower units. Further, the point of the SM2260 is likely to get a low cost NVMe PCIe SSD controller into the hands of SSD makers, which can only mean good things for those looking to make the move away from SATA.

It turns out Samsung wasn’t the only company to have 16TB SSDs at Flash Memory Summit after all:
Now that I’ve got your attention, Novachips is an SSD company that does not make their own flash, but I would argue that they make other peoples flash better. They source flash memory wafers and dies from other companies, but they package it in a unique way that enables very large numbers of flash dies per controller. This is handy for situations where very large capacities per controller are needed (either physically or logically).
Normally there is a limit to the number of dies that can communicate on a common bus (similar limits apply to DRAM, which is why some motherboards are picky with large numbers of DIMMs installed). Novachips gets around this with an innovative flash packaging method:
The 16-die stack in the above picture would normally just connect out the bottom of the package, but in the Novachips parts, those connections are made to a microcontroller die also present within the package. This part acts as an interface back to the main SSD controller, but it does so over a ring bus architecture.
To clarify, those 800 or 1600 MB/sec figures on the above slide are the transfer rates *per ring*, and Novachips controller is 8-channels, meaning the flash side of the controller can handle massive throughputs. Ring busses are not limited by the same fanout requirements seen on parallel addressed devices, which means there is no practical limit to the number of flash packages connected on a single controller channel, making for some outrageous amounts of flash hanging off of a single controller:
That’s a lot of flash on a single card (and yes, the other side was full as well).
The above pic was taken at last years Flash Memory Summit. Novachips has been making steady progress on controller development as well. Here is a prototype controller seen last year running on an FPGA test system:
…and this year that same controller had been migrated to an ASIC:
It’s interesting to see the physical differences between those two parts. Note that both new and old platforms were connected to the same banks of flash. The newer photo showed two complete systems – one on ONFi flash (IMFT Intel / Micron) and the other on Toggle Mode (Toshiba). This was done to demonstrate that Novachips HLNAND hardware is compatible with both types.
Novachips also had NVMe PCIe hardware up and running at the show.
Novachips was also showing some impressive packaging in their SATA devices:
At the right was a 2TB SATA SSD, and at the left was a 4TB unit. Both were in the 7mm form factor. 4TB is the largest capacity SSD I have seen in that form factor to date.
Novachips also makes an 8TB variant, though the added PCB requires 15mm packaging.
All of this means that it is not always necessary to have huge capacity per die to achieve a huge capacity SSD. Imagine very high capacity flash arrays using this technology, connecting a single controller to a bank of Toshiba’s new QLC archival flash or Samsung’s new 256Gbit VNAND. Then imagine a server full of those PCIe devices. Things certainly seem to be getting big in the world of flash memory, that’s for sure.

We occasionally throw around the '3-bit MLC' (Multi Level Cell) term in place of 'TLC' (Triple Level Cell) when talking about flash memory. Those terms are interchangeable, but some feel it is misleading as the former still contains the term MLC. At Toshiba's keynote today, they showed us why the former is important:
Photo source: Sam Chen of Custom PC Review
That's right - QLC (Quadruple Level Cell), which is also 4-bit MLC, has been mentioned by Toshiba. As you can see at the right of that slide, storing four bits in a single flash cell means there are *sixteen* very narrow voltage ranges representing the stored data. That is a very hard thing to do, and even harder to do with high performance (programming/writing would take a relatively long time as the circuitry nudges the voltages to such a precise level). This is why Toshiba pitched this flash as a low cost solution for archival purposes. You wouldn't want to use this type of flash in a device that was written constantly, since the channel materials wearing out would have a much more significant effect on endurance. Suiting this flash to be written only a few times would keep it in a 'newer' state that would be effective for solid state data archiving.
The 1x / 0.5x / 6x figures appearing in the slide are meant to compare relative endurance to Toshiba's own planar 15nm flash. The figures suggest that Toshiba's BiCS 3D flash is efficient enough to go to QLC (4-bit) levels and still maintain a higher margin than their current MLC (2-bit) 2D flash.

I get these emails and comments all the time - "I want a larger capacity SSD". Ok, here ya go:
Samsung's earlier 48-layer VNAND announcement was exciting, but we already knew about it going into the keynote. What we did not know was that Samsung was going to blew the doors off of their keynote when they dropped this little gem. It's not just the largest capacity SSD, as this thing is more dense than any HDD's available today as well. That's 16TB of 48-layer TLC VNAND packed into a 2.5" form factor SAS-connected SSD.
...now what do you do once you have such a high density device? Well, you figure out how many you can cram into a 2U chassis of course!
Yup, that's 48 of those new SSDs, making for a capacity of 768TB in a 2U chassis. Samsung described this as a "JBOF" (Just a Bunch Of Flash), so processing the 2 million IOPS this array is capable of will have to be left to the connected system.
No word on pricing, but I'd think we are in 'mortgage the house' territory if you want to put this into your home PC.
There is more to follow from Flash Memory Summit, but for now I've got to run to another meeting!
FMS 2015: *UPDATED* Samsung Adds Layers to its 3D VNAND, Doubling Capacity While Reducing Power Consumption

FMS 2015: Samsung Adds Layers to its 3D VNAND, Doubling Capacity While Reducing Power Consumption
Samsung recently added 2TB capacity parts to their 850 EVO SATA SSDs, but today’s announcement may double that. Today at Flash Memory Summit, Samsung has announced a new iteration on their 3D VNAND technology.
Cross section of Samsung 32-layer VNAND. (TechInsights)
The announcement is a new TLC 3D VNAND (the type present in the 850 EVO Series). The new parts consist of an updated die with the following improvements:
- 48 layer VNAND - up from 32 layers of the previous generation
- 256Gbit (32GB) capacity - up from 128Gbit (16GB) capacity of 32-layer VNAND
- 30% reduction in power consumption over 32-layer VNAND
Samsung’s new 48-layer VNAND.
I suspected Samsung would go this route in order to compete with the recent announcements from Intel/Micron and SanDisk. Larger die capacities may not be the best thing for keeping performance high in smaller capacity SSDs (a higher number of smaller capacity dies helps there), but it is definitely a good capability to have since higher capacity per die translates to more efficient flash die production.
The Samsung keynote is at noon today (Pacific), and I will update this piece with any photos relevant to the announcement after that keynote.
I just got out of the Samsung keynote. There were some additional slides with data relevant to this post:
This image simply shows the additional vertical stacking, but adds that Samsung has this new flash in production right now.
The new higher capacity dies enable 1.4x greater density per wafer (realize that this does not mean more dies per wafer, as the image incorrectly suggests).
The power consumption improvements (right) were in the press release, however the speed improvements (left) were not. A 2x improvement in per-die speeds means that Samsung should not see a performance hit if they migrate their existing 128Gbit TLC VNAND SSDs over to these new 256Gbit parts. Speaking of which...
Not only is this new VNAND being produced *this month*, Samsung is retrofitting their 850 EVO line with the new parts. Again, we expect no performance delta but will likely retest these new versions just to double check for any outliers.
There was some more great info from the keynote, but that will appear in another post later today.

ADATA's new XPG SX930 series is aimed at enthusiasts on a budget, the 120GB is about $65, the 240GB at $110 and the 480GB at $200. The SSDs use the JMicron JMF670H controller, not one we have seen before and they also have a pseudo SLC cache which grows with the size of the drive from 4GB to 8GB to 16GB for the 480GB model. The SSD Review tested out all three drives and found that the advertised speeds of 550MB/s read and 460MB/s write were more or less accurate and the drives did fairly well in their other tests as well. If you need more speedy storage and are on a budget you should check out their full review.
"ADATA has memory products for all sections of the market, from consumer to industrial. As of late they have released a new consumer SSD, the XPG SX930. It is marketed towards the gamer and overclocker crowd at a pretty competitive price point."

A new 800GB SKU of the Intel SSD 750 Series of PCIe SSDs was hinted at with the Skylake launch press materials, and it appears to have been a reality:
They may not be on the shelves yet, but appearing on ARK is a pretty good indicator that these are coming soon. We don't have pricing yet, but I would suspect a cost/GB closer to the 1.2TB model than to the 400GB model, which should come in at around $700. Performance sees a slight hit for the 800GB model, likely since this is an 'uneven' number of dies for the design of the SSD DC P3500 line it was based on.
Which would you prefer - a single 800GB or a pair of 400GB SSD 750's in a RAID (now that it is possible)?

Tagged: XPoint, non-volatile RAM, micron, memory, Intel
Everyone that reads SSD reviews knows that NAND Flash memory comes with advantages and disadvantages. The cost is relatively good as compared to RAM, and the data remains even with power removed (non-volatile), but there are penalties in the relatively slow programming (write) speeds. To help solve this, today Intel and Micron jointly launched a new type of memory technology.
XPoint (spoken 'cross point') is a new class of memory technology with some amazing characteristics. 10x the density (vs. DRAM), 1000x the speed, and most importantly, 1000x the endurance as compared to current NAND Flash technology.
128Gb XPoint memory dies, currently being made by Intel / Micron, are of a similar capacity to current generation NAND dies. This is impressive for a first generation part, especially since it is physically smaller than a current gen NAND die of the same capacity.
Intel stated that the method used to store the bits is vastly different from what is being used in NAND flash memory today. Intel stated that the 'whole cell' properties change as a bit is being programmed, and that the fundamental physics involved is different, and that it is writable in small amounts (NAND flash must be erased in large blocks). While they did not specifically state it, it looks to be phase change memory (*edit* at the Q&A Intel stated this is not Phase Change). The cost of this technology should end up falling somewhere between the cost of DRAM and NAND Flash.
3D XPoint memory is already being produced at the Intel / Micron Flash Technology plant at Lehi, Utah. We toured this facility a few years ago.
Intel and Micron stated that this technology is coming very soon. 2016 was stated as a launch year, and there was a wafer shown to us on stage:
You know I'm a sucker for good wafer / die photos. As soon as this session breaks I'll get a better shot!
There will be more analysis to follow on this exciting new technology, but for now I need to run to a Q&A meeting with the engineers who worked on it. Feel free to throw some questions in the comments and I'll answer what I can!
*edit* - here's a die shot:
Added note - this wafer was manufactured on a 20nm process, and consists of a 2-layer matrix. Future versions should scale with additional layers to achieve higher capacities.
AMD is exploring alternate product routes to raise their income and the latest seems to be the Puma powered QNAP TVS-x63. It is a four bay NAS which is powered by the 2.4GHz AMD GX424-CC SoC which happens to have a 28 stream processor GCN Radeon clocked at 497 MHz. It has a pair of gigabit ports with an optional add-in card offering a single 10Gb or two additional 1Gb ports, though that will raise you above the cost of the $630 base model. Bjorn3d found the power consumption to be higher than the competition but the overall operation was flawless.
"The QNAP TVS-x63 marked the world’s first NAS featuring AMD processor. AMD’s new strategy is targeting the markets with high profit return and the company is returning to the server market. NAS, by extension, is like a small scale server, so it makes sense to see AMD putting their processors into these devices."

...you get the Samsung PM863 and SM863 lines of enterprise SSDs! These 2.5" SATA units were just announced, and as we suspected after reviewing the new 2TB 850 EVO and Pro, these new models can include even more flash packages, dramatically increasing the flash capacity. Here is a breakdown of the launch pricing and capacities:
SM863 (2-bit MLC VNAND):
- 120GB - $140 ($1.17/GB)
- 240GB - $180 ($0.75/GB)
- 480GB - $330 ($0.69/GB)
- 960GB -
$870 ($0.91/GB) < possible typo$640 ($0.67/GB)
- 1.92TB - $1260 ($0.66/GB)
PM863 (3-bit MLC VNAND):
- 120GB - $125 ($1.04/GB)
- 240GB - $160 ($0.67/GB)
- 480GB - $290 ($0.60/GB)
- 960GB - $550 ($0.57/GB)
- 1.92TB - $1100 ($0.57/GB)
- 3.84TB - $2200 ($0.57/GB)
These are some very competitive prices for enterprise SSDs, and the fact that the TLC version can cram just under 4TB into a 7mm 2.5" form factor is just astounding. The MLC version capacities appear to still follow that of the 850 Pro, minus a bit of available capacity due to higher levels of over-provisioning.
More impressive is the endurance ratings of these SSDs. The SM863 line is rated (varying by capacity) from 770 Terabytes Written (TBW) to an astonishing 12,320 TBW for the 1.92TB model! That's over 12 Petabytes! The PM863 is rated lower as it is TLC based, but is still no slouch as it ranges from 170 to 5,600 TBW for the 3.84TB capacity. The SM863 carries a 5-year warranty, while the PM863 drops that to 3-years.
We've been waiting to see Samsung's 32-layer VNAND appear in enterprise units for some time now, and look forward to testing them just as soon as we can get our hands on them!
Full press blast after the break.

[H]ard|OCP has just posted a roundup of four affordable SATA SSDs to show which would be the best one to pick up as the majority of users are not able to afford an NVME PCIe SSD. The drives are all within $50 above or below $200, with the 850 PRO having the highest cost per gigabyte and the EVO the least. They test content creation and moving large files as well as synthetic benchmarks to come out with a ranking of the four drives which you can refer to if you will be shopping for storage in the near future. In comparison they use the G.SKILL Phoenix Blade to show off what the new technology can do, for those that can afford it.
"Despite the performance benefits, PCIe SSDs remain an expensive niche market. That means that most of us are not going to be loading up a high end system with PCIe SSDs. Most of us mere mortals will be using SATA SSDs. We tested some of the best SATA drives with enthusiast-friendly price tags."

Samsung is extending their 850 EVO and Pro lineups to include 2TB versions of the popular SSDs thanks to the use of 3D-VNAND; three bit memory on the EVO and two bit on the Pro. They are rated at the same speeds as their 500GB and above counterparts and The SSD Review had a chance to test that. Interestingly they did indeed find performance differences between the 1TB and 2TB model of the same design, which you can check out in the full review. Their results were not quite the same as Al's review which was just posted, you should compare the two reviews as well as the systems used for theories on why that is. You can expect to pay ~$1000 for the 850 Pro 2TB and ~$800 for the 850 EVO 2TB.
"If you look back over the past several years, there have always been three constants that needed to be addressed in order for SSDs to become a viable consumer solution to storage; value, reliability and capacity. One of our first SSD reviews was on an MTron 32GB SSD with a whopping price tag of more than $1500…and they sold!"

Samsung's M.2 SM951 PCIe SSD was never originally intended to be sold on its own but thankfully the 128, 256 and 512GB models are showing up on Newegg and other sites and the speeds it can reach are very impressive. The Tech Report tested the 512GB model and saw it beat the Intel 750 Series in IOMeter at a queue depth of one, though the Intel SSD still shows off its prowess at higher queue depths. Their testing showed that the speed of the flash produces enough heat that the drive throttles itself so you should consider rigging an active cooling solution if you do pick up this drive. Check out their full review to see some very impressive numbers and boot times.
"Samsung's SM951 SSD squeezes a quad-lane PCIe Gen3 interface onto a diminutive M.2 form factor. It offers incredible performance under the right conditions, but it also struggles in some scenarios. Our in-depth review explains the drive's strengths, weaknesses, and unique enthusiast appeal."
