The Kingston DCP1000 NVMe PCIe SSD comes in 800GB, 1.6TB, and 3.2TB though as it is an Enterprise class drive even the smallest size will cost you over $1000. Even with a price beyond the budget of almost all enthusiasts it is interesting to see the performance of this drive, especially as Kitguru's testing showed it to be faster than the Intel D P3608. Kitguru cracked the 1.6TB card open to see how it worked and within found four Kingston 400GB NVMe M.2 SSDs, connected by a PLX PEX8725 24-lane, 10-port PCIe 3.0 switch which then passes the data onto the cards PCIe 3.0 x8 connector. Each of those 400GB SSDs have their own PhisonPS5007-11 eight channel quad-core controller which leads to very impressive performance. They did have some quibbles about the performance consistency of the drive; however it is something they have seen on most drives of this class and not something specific to Kingston's drive.
"Move over Intel DC P3608, we have a new performance king! In today’s testing, it was able to sustain sequential read and write speeds of 7GB/s and 6GB/s, respectively! Not only that, but it is able to deliver over 1.1million IOPS with 4KB random read performance and over 180K for write."

Tagged: x299, VROC, Virtual RAID on CPU, raid, Intel, asus
Ken and I have been refreshing our Google search results ever since seeing the term 'VROC' slipped into the ASUS press releases. Virtual RAID on CPU (VROC) is a Skylake-X specific optional feature that is a carryover from Intel's XEON parts employing RSTe to create a RAID without the need for the chipset to tie it all together.
Well, we finally saw an article pop up over at PCWorld, complete with a photo of the elusive Hyper M.2 X16 card:
The theory is that you will be able to use the 1, 2, or 3 M.2 slots of an ASUS X299 motherboard, presumably passing through the chipset (and bottlenecked by DMI), or you can shift the SSDs over to a Hyper M.2 X16 card and have four piped directly to the Skylake-X CPU. If you don't have your lanes all occupied by GPUs, you can even add additional cards to scale up to a max theoretical 20-way RAID-0 supporting a *very* theoretical 128GBps.
A couple of gotchas here:
- Only works with Skylake-X (not Kaby Lake-X)
- RAID-1 and RAID-5 are only possible with a dongle (seriously?)
- VROC is supposedly only bootable when using Intel SSDs (what?)
Ok, so the first one is understandable given Kaby Lake-X will only have 16 PCIe lanes direclty off of the CPU.
The second is, well, annoying, but understandable once you consider that some server builders may want to capitalize on the RSTe-type technology without having to purchase server hardware. It's still a significant annoyance, because how long has it been since anyone has had to deal with a freaking hardware dongle to unlock a feature on a consumer part. That said, most enthusiasts are probably fine with RAID-0 for their SSD volume, given they would be going purely for increased performance.
The third essentially makes this awesome tech dead on arrival. Requiring only Intel branded M.2 SSDs for VROC bootability is a nail in the coffin. Enthusiasts are not going to want to buy 4 or 8 (or more) middle of the road Intel SSDs (the only M.2 NAND SSD available from Intel is the 600p) for their crazy RAID - they are going to go with something faster, and if that can't boot, that's a major issue.
More to follow as we learn more. We'll keep a lookout and keep you posted as we get official word from Intel on VROC!

Tagged: TS-x77, amd, ryzen, qnap, NAS, computex 2017
QNAP are providing a sneak peak of a new line of NAS devices, powered by AMD's Ryzen processors. The TS-x77 series will come in 6, 8, and 12-bay models with an AMD Ryzen 7 1700 or Ryzen 5 1600 or 1400 processor with up to 8, 16, 32 or 64GB DDR4 RAM dependant on the model.
The devices support RAID 0/1/5/6/10/50/60, RAID 1/5/6/10/50/60 + spare, single and JBOD, which support AES-NI encryption acceleration. Internally there are quite a lot of opportunities to customize your NAS, on all models you will find a pair of M.2 2242/2260/2280/22110 SATA 6 Gb/s SSD slots for your hot storage and depending on the model you will have a mix of 2.5" and dual 2.5/3.5" drive bays for your SSDs or HDDs.
That is not the only possibilities for expansion in these NAS devices, all models contain three PCIe 3.0, one 8x slot and two 4x which you can use for a PCIe SSD, 10GbE or 40GbE network cards or perhaps even a GPU for local transcoding. Externally you have four Gigabit ethernet connectors, two USB 3.1 ports, one Type-C and one Type-A as well as five USB 3.0 ports.
These will not be available until Q3, so we won't be able to review it for a while but rest assured that we are at least as interesting in seeing the performance of Ryzen in a NAS as you are.

Tagged: toshiba, ssd, ocz, NVMe, nand, M.2, computex 2017, BiCS, 64-Layer
Last night we saw WD launch the first client SSDs with 64-layer NAND Flash, but recall that WD/SanDisk is in partnership with Toshiba to produce this new gen 3 BiCS memory, which means Toshiba is also launching their own product wrapped around this new high-density flash:
Enter the Toshiba XG5. It is certainly coming on strong here, as evidenced by the specs:
Unlike the WD/SanDisk launch, the BiCS flash on this Toshiba variant sits behind an NVMe SSD controller, with stated read speeds at 3GB/s and writes just over 2 GB/s. We don't yet have random performance figures, but we expect it to certainly be no slouch given the expected performance of this newest generation of flash memory. Let's take a quick look at some of the high points there:
Alright, so we have the typical things you'd expect, like better power efficiency and higher endurance, but there is a significant entry there under the performance category - 1-shot, full sequence programming. This is a big deal, since writing to flash memory is typically done in stages, with successive program cycles nudging cell voltages closer to their targets with each pass. This takes time and is one of the main things holding back the write speeds of NAND flash. This new BiCS is claimed to be able to successfully write in a single program cycle, which should translate to noticeable improvements in write latency.
Another thing helping with writes is that the XG5 will have its BiCS flash operating in a hybrid mode, meaning these are TLC SSDs with an SLC cache. We do not have confirmed cache sizes to report, but it's a safe bet that they will be similar to competing products.
We don't yet have pricing info, but we do know that the initial capacity offerings will start with 256GB, 512GB, and 1TB offerings. The XG5 is launching in the OEM channel in the second half of 2017. While this one is an OEM product, remember that OCZ is Toshiba's brand for client SSDs, so there's a possibility we may see a retail variant appear under that name in the future.

Tagged: western digital, wdc, WD, Ultra, ssd, sandisk, nand, computex 2017, Blue, BiCS, 3d
Western Digital bought SanDisk nearly two years ago, but we had not really seen any products jointly launched under both brand labels. Until today:
The WD Blue 3D NAND SATA SSD and SanDisk Ultra 3D SSD are both products containing identical internals. Specifically, these are the first client SSDs built with 64-layer 3D NAND technology. Some specs:
- Sequential read: 560 MB/s
- Sequential write: 530 MB/s
- Capacity: 250GB, 500GB, 1TB, 2TB
- Form factor: 2.5" (WD and Sandisk), M.2 (SATA) 2280 (WD only)
MSRP's start at $99.99 for the 250GB models of all flavors (2.5" / M.2 SATA), and all products will ship with a 3-year warranty.
It might seem odd that we see an identical product shipped under two different brands owned by the same company, but WD is likely leveraging the large OEM relationship held by SanDisk. I'm actually curious to see how this pans out long term because it is a bit confusing at present.

Tagged: XPoint, Intel, HPC, DIMM, 3D XPoint
Intel recently teased a bit of new information on its 3D XPoint DIMMs and launched its first public demonstration of the technology at the SAP Sapphire conference where SAP’s HANA in-memory data analytics software was shown working with the new “Intel persistent memory.” Slated to arrive in 2018, the new Intel DIMMs based on the 3D XPoint technology developed by Intel and Micron will work in systems alongside traditional DRAM to provide a pool of fast, low latency, and high density nonvolatile storage that is a middle ground between expensive DDR4 and cheaper NVMe SSDs and hard drives. When looking at the storage stack, the storage density increases along with latency as it gets further away from the CPU. The opposite is also true, as storage and memory gets closer to the processor, bandwidth increases, latency decreases, and costs increase per unit of storage. Intel is hoping to bridge the gap between system DRAM and PCI-E and SATA storage.
According to Intel, system RAM offers up 10 GB/s per channel and approximately 100 nanoseconds of latency. 3D XPoint DIMMs will offer 6 GB/s per channel and about 250 nanoseconds of latency. Below that is the 3D XPoint-based NVMe SSDs (e.g. Optane) on a PCI-E x4 bus where they max out the bandwidth of the bus at ~3.2 GB/s and 10 microseconds of latency. Intel claims that non XPoint NVMe NAND solid state drives have around 100 microsecomds of latency, and of course, it gets worse from there when you go to NAND-based SSDs or even hard drives hanging of the SATA bus.
Intel’s new XPoint DIMMs have persistent storage and will offer more capacity that will be possible and/or cost effective with DDR4 DRAM. In giving up some bandwidth and latency, enterprise users will be able to have a large pool of very fast storage for storing their databases and other latency and bandwidth sensitive workloads. Intel does note that there are security concerns with the XPoint DIMMs being nonvolatile in that an attacker with physical access could easily pull the DIMM and walk away with the data (it is at least theoretically possible to grab some data from RAM as well, but it will be much easier to grab the data from the XPoint sticks. Encryption and other security measures will need to be implemented to secure the data, both in use and at rest.
Interestingly, Intel is not positioning the XPoint DIMMs as a replacement for RAM, but instead as a supplement. RAM and XPoint DIMMs will be installed in different slots of the same system and the DDR4 RAM will be used for the OS and system critical applications while the XPoint pool of storage will be used for storing data that applications will work on much like a traditional RAM disk but without needing to load and save the data to a different medium for persistent storage and offering a lot more GBs for the money.
While XPoint is set to arrive next year along with Cascade Lake Xeons, it will likely be a couple of years before the technology takes off. Supporting it is going to require hardware and software support for the workstations and servers as well as developers willing to take advantage of it when writing their specialized applications. Fortunately, Intel started shipping the memory modules to its partners for testing earlier this year. It is an interesting technology and the DIMM solution and direct CPU interface will really let the 3D XPoint memory shine and reach its full potential. It will primarily be useful for the enterprise, scientific, and financial industries where there is a huge need for faster and lower latency storage that can accommodate massive (multiple terabyte+) data sets that continue to get larger and more complex. It is a technology that likely will not trickle down to consumers for a long time, but I will be ready when it does. In the meantime, I am eager to see what kinds of things it will enable the big data companies and researchers to do! Intel claims it will not only be useful at supporting massive in-memory databases and accelerating HPC workloads but for things like virtualization, private clouds, and software defined storage.
What are your thoughts on this new memory tier and the future of XPoint?

Tagged: SolidScale, NVMf, NVMe, micron, fabric, Cassandra
A few weeks back, I was briefed on Micron’s new SolidScale Architecture. This is essentially Micron’s off-the-shelf solution that ties together a few different technologies in an attempt to consolidate large pools of NVMe storage into a central location that can then be efficiently segmented and distributed among peers and clients across the network.
Traditionally it has been difficult to effectively utilize large numbers of SSDs in a single server. The combined IOPS capabilities of multiple high-performance PCIe SSDs can quickly saturate the available CPU cores of the server due to kernel/OS IO overhead incurred with each request. As a result, a flash-based network server would be bottlenecked by the server CPU during high IOPS workloads. There is a solution to this, and it’s simpler than you might think: Bypass the CPU!

Corsair have entered the NVMe market with a new Force Series product, the MP500 drive which contains Toshiba's 15-nm MLC, run by the popular Phison PS5007-E7 controller. There is a difference which The Tech Report noticed right away, that sticker is for more than just show, it hides a layer of heat-dissipating copper inside just like we have seen in Samsung products. It may have been the sticker, or some sort of secret sauce which Corsair added but the MP500's performance pulled ahead of Patriot's Hellfire SSD overall. Read the full review to see where the drive showed the most performance differential.
"Corsair is throwing its hat into the NVMe SSD ring with the Force Series MP500 drive. We subjected this gumstick to our testing gauntlet to see how well the 240GB version fares against the rest of the formidable NVMe field."

Tagged: western digital, wdc, WD, Red Pro, red, NAS, helium, HelioSeal, hdd, Hard Drive, 10TB
Western Digital increased the capacity of their Red and Red Pro NAS hard disk lines to 10TB. Acquiring the Helioseal technology via their HGST acquisition, which enables Helium filled hermetically sealed drives of even higher capacities, WD expanded the Red lines to 8TB (our review of those here) using that tech. Helioseal has certainly proven itself, as over 15 million such units have shipped so far.
We knew it was just a matter of time before we saw a 10TB Red and Red Pro, as it has been some time since the HGST He10 launched, and Western Digital's own 10TB Gold (datacenter) drive has been shipping for a while now.
- Red 10TB: $494
- Red Pro 10TB: $533
MSRP pricing looks a bit high based on the lower cost/GB of the 8TB model, but given some time on the market and volume shipping, these should come down to match parity with the lesser capacities.
Press blast appears after the break.

At $44 for 16GB or $77 for a 32GB module Intel's Optane memory will cost you less in total for an M.2 SSD, though a significantly higher price per gigabyte. The catch is that you need to have a Kaby Lake Core system to be able to utilize Optane, which means you are unlikely to be using a HDD. Al's test show that Optane will also benefit a system using an SSD, reducing latency noticeably although not as significantly as with a HDD.
The Tech Report tested it differently, by sourcing a brand new desktop system with Kaby Lake Core APU that did not ship with an SSD. Once installed, the Optane drive enabled the system to outpace an affordable 480GB SSD in some scenarios; very impressive for a HDD. They also did peek at the difference Optane makes when paired with aforementioned affordable SSD in their full review.
"Intel's Optane Memory tech purports to offer most of the responsiveness of an SSD to systems whose primary storage device is a good old hard drive. We put a 32GB stick of Optane Memory to the test to see whether it lives up to Intel's claims."

ADATA has added another line of M.2 PCIe SSDs to their catalog with the XPG SX7000. These drives support NVMe and claim up to 1800 MB/s sequential read performance and 850 MB/s sequential write performance, with both tests measured on CrystalDiskMark at a queue depth of 32. Interestingly enough, their ATTO sequential write results, 860 MB/s, exceed their claimed maximum. Again, each of these numbers are provided by ADATA, so it’s still up to third-parties (like us) to verify. That said, ADATA provided a lot of information in their performance chart, which is nice to see.
The spec sheet (pdf) provides performance results for three SKUs: 128GB, 256GB, and 512GB. A fourth model (if you guessed 1TB, then you would be right) is also acknowledged, but not elaborated upon. These are all based on 3D TLC flash, with some undefined amount of SLC cache.
Pricing and availability are TBD, but it will come with a 5 year warranty.

For those who don't want to get into networked storage solutions but still require external storage with more options than a simple USB drive offers, direct attached storage devices are a good solution. The Noontec-TerraMaster D2-310 is an aluminium shell with two drive bays, connected via Type-C USB 3.1 and offers support for JBOD, RAID 0 and RAID 1 in addition to simply presenting two external disks. Modders-Inc tested this DAS in two different configurations, a pair of Seagate 4 TB 7200 RPM HDDs as well as a pair of Samsung 850 EVO 256 SSDs. The performance levels reached their expectations, however the price is a bit higher than the competition; examine their results and description of the device to determine if you feel it is worth the expense.
"D2-310 is a direct attached storage device by Noontec-TerraMaster. Most of the market is moving away from DAS devices to network based devices however, there is still a need for simple and fast solutions to store data locally.

Tagged: XPoint, Optane Memory, Optane, M.2, Intel, cache, 3D XPoint
We are just about to hit two years since Intel and Micron jointly launched 3D XPoint, and there have certainly been a lot of stories about it since. Intel officially launched the P4800X last week, and this week they are officially launching Optane Memory. The base level information about Optane Memory is mostly unchanged, however, we do have a slide deck we are allowed to pick from to point out some of the things we can look forward to once the new tech starts hitting devices you can own.
Alright, so this is Optane Memory in a nutshell. Put some XPoint memory on an M.2 form factor device, leverage Intel's SRT caching tech, and you get a 16GB or 32GB cache laid over your system's primary HDD.
To help explain what good Optane can do for typical desktop workloads, first we need to dig into Queue Depths a bit. Above are some examples of the typical QD various desktop applications run at. This data is from direct IO trace captures of systems in actual use. Now that we've established that the majority of desktop workloads operate at very low Queue Depths (<= 4), lets see where Optane performance falls relative to other storage technologies:
There's a bit to digest in this chart, but let me walk you through it. The ranges tapering off show the percentage of IOs falling at the various Queue Depths, while the green, red, and orange lines ramping up to higher IOPS (right axis) show relative SSD performance at those same Queue Depths. The key to Optane's performance benefit here is that it can ramp up to full performance at very low QD's, while the other NAND-based parts require significantly higher parallel requests to achieve full rated performance. This is what will ultimately lead to a much snappier responsiveness for, well, just about anything hitting the storage. Fun fact - there is actually a HDD on that chart. It's the yellow line that you might have mistook as the horizontal axis :).
As you can see, we have a few integrators on board already. Official support requires a 270 series motherboard and Kaby Lake CPU, but it is possible that motherboard makers could backport the required NVMe v1.1 and Intel RST 15.5 requirements into older systems.
For those curious, if caching is the only way power users will be able to go with Optane, that's not the case. Atop that pyramid there sits an 'Intel Optane SSD', which should basically be a consumer version of the P4800X. It is sure to be an incredibly fast SSD, but that performance will most definitely come at a price!
We should be testing Optane Memory shortly and will finally have some publishable results of this new tech as soon as we can!

A new line of USB flash drives has been announced by Lexar, which focuses on both durability and USB 3.1 support (compatible with USB 2.0 and USB 3.0). From the technical side, the Lexar JumpDrive Tough drives can read up to 150 MB/s and write up to 60 MB/s, which is obviously nowhere near SSD speed, but reasonably fast for the typical cases that you would use a thumb drive.
As for its robustness, Lexar claims that the JumpDrive Tough will operate normally between -13F and 300F, which is just shy of the bake cookies temperature. It is also water resistant up to 98 feet.
The Lexar JumpDrive Tough will be available in 32GB, 64GB, and 128GB models for $19.99, $34.99, and $59.99, respectively. While I don’t normally consider manufacturer returns for something like this, Lexar is backing this purchase with a 3-year limited warranty, which gives some legal teeth to their claims (if anyone takes them up on it). They are available now.

The Seagate Barracuda Pro 10TB Enterprise HDD won't give you the fastest access to your data, but if you have a large amount of storage in a reliable format it is worth looking at this review. The MSRP of $444.45USD is much lower than you would pay for 10TB of SSD storage, though you might be able to set up several smaller disks in a Drobo or similar device for a similar price. The MTBF is 2.5 million hours, the endurance rating is 550TB per year and there is a 5 year warranty so even with heavy usage you should be able to depend on this drive for quite a long time. You can drop by NikKTech to see how it performs.

Intel brought us out to their Folsom campus last week for some in-depth product briefings. Much of our briefing is still under embargo, but the portion that officially lifts this morning is the SSD DC P4800X:
MSRP for the 375GB model is estimated at $1520 ($4/GB), which is rather spendy, but given that the product has shown it can effectively displace RAM in servers, we should be comparing the cost/GB with DRAM and not NAND. It should also be noted this is also nearly half the cost/GB of the X25-M at its launch. Capacities will go all the way up to 1.5TB, and U.2 form factor versions are also on the way.
For those wanting a bit more technical info, the P4800X uses a 7-channel controller, with the 375GB model having 4 dies per channel (28 total). Overprovisioning does not do for Optane what it did for NAND flash, as XPoint can be rewritten at the byte level and does not need to be programmed in (KB) pages and erased in larger (MB) blocks. The only extra space on Optane SSDs is for ECC, firmware, and a small spare area to map out any failed cells.
Those with a keen eye (and calculator) might have noted that the early TBW values only put the P4800X at 30 DWPD for a 3-year period. At the event, Intel confirmed that they anticipate the P4800X to qualify at that same 30 DWPD for a 5-year period by the time volume shipment occurs.

As we are not going to see scanning tunnelling microscopes included in our home computers anytime soon this experiment is simply proof of the concept that data can be stored on a single atom. That does not make it any less interesting for those fascinated by atomic storage techniques. A single atom of holmium can be made to spin either up or down, signifying either a 0 or 1, and that spin state can be 'read' by measuring the vibration of a single iron atom located close by. The holmium atoms used for storage can be separated by a mere nanometer without interfering with the spin of its neighbours. The spin state only lasts a few hours but shows that this could someday be a viable storage technology. You can read more at nanotechweb, who also have links to the Nature article.
"Information has been stored in a single atom for the first time. The nascent binary memory was created by Andreas Heinrich at the Institute of Basic Science in South Korea and an international team."

The Server 5 is a completely different twist for an ioSafe NAS. While previous units have essentially been a fireproof drive cage surrounding Synology NAS hardware, the Server 5 is a full blown Xeon D-1520 or D-1521 quad core HT, 16GB of DDR4, an Areca ARC-1225-8i hardware RAID controller (though only 5 ports are connected to the fireproof drive cage). ioSafe supports the Server 5 with Windows Server 2012 R2 or you can throw your preferred flavor of Linux on there. The 8-thread CPU and 16GB of RAM mean that you can have plenty of other services running straight off of this unit. It's not a particularly speedy CPU, but keep in mind that the Areca RAID card offloads all parity calculations from the host.
Overall the Server 5 looks nearly identical to the ioSafe 1515+, but with an extra inch or two of height added to the bottom to accommodate the upgraded hardware. The Server 5 should prove to be a good way to keep local enterprise / business data protected and available immediately after a disaster. While only the hard drives will be protected in a fire, they can be popped out of the charred housing and shifted to a backup Server 5 or just migrated to another Areca-driven NAS system. For those wondering what a typical post-fire ioSafe looks like, here ya go:
Note how clean the cage and drives are (and yes, they all still work)!
Press blast appears after the break.

While this is more useful for our readers in the IT field, NETGEAR has issued a (non-urgent) recall on sixteen models of Rackmount NAS and Wireless Controller devices. It looks like the reason for this announcement is to maintain customer relations. They are planning to reach out to customers “over the next several months” to figure out a solution for them. Note the relaxed schedule.
The affected model numbers are:
- WC7500 Series:
- WC7500-10000S, WC7500-100INS, WC7500-100PRS, WB7520-10000S, WB7520-100NAS, WB7530-10000S, WB7530-100NAS
- WC7600 Series:
- WC7600-20000S, WC7600-200INS, WC7600-200PRS, WB7620-10000S, WB7620-100NAS, WB7630-10000S, WB7630-100NAS
The Register noticed that each of these devices contain Intel’s Avoton-based Atom processors. You may remember our coverage from last month, which also sourced The Register, that states these chips may fail to boot over time. NETGEAR is not blaming Intel for their recall, but gave The Register a wink and a nudge when pressed: “We’re not naming the vendor but it sounds as if you’ve done your research.”
Again, while this news applies to enterprise customers and it’s entirely possible that Intel (if it actually is the Avoton long-term failure issue) is privately supporting them, it’s good to see NETGEAR being honest and upfront. Problems will arise in the tech industry; often (albeit not always) what matters more is how they are repaired.
