Brace Yourselves, Samsung SM961, PM961, 960 PRO and 960 EVO SSDs Are Coming!

Subject: Storage | June 21, 2016 - 04:02 PM |
Tagged: V-NAND, SM961, Samsung, PM961, 960 PRO, 960 EVO, 48-layer

We've known Samsung was working on OEM-series SSDs using their new 48-layer V-NAND, and it appears they are getting closer to shipping in volume, so here's a peek at what is to come:


First up are the SM961 and PM961. The SM and PM appear to be converging into OEM equivalents of the Samsung 'PRO' and 'EVO' retail product lines, with MLC flash present in the SM and TLC (possibly with SLC TurboWrite cache) in the PM. The SM961 has already been spotted for pre-order over at Ram City. Note that they currently list the 1TB, 512GB, and 256GB models, but at the time of this writing, all three product titles (incorrectly) state 1TB. That said, pricing appears to be well below the current 950 PRO retail for equivalent capacities.


These new parts certainly have impressive specs on paper, with the SM961 claiming a 25-50% gain over the 950 PRO in nearly all metrics thanks to 48-layer V-NAND and an updated 'Polaris' controller. We've looked at plenty of Samsung OEM units in the past, and sometimes specs differ between OEM and retail parts, but it is starting to make sense for Samsung to simply relabel a given OEM / retail part at this point (minus any vendor-requested firmware detuning, like reduced write speeds in favor of increased battery life, etc).

With that are the other two upcoming parts that do not appear on the above chart. Those will be the 960 PRO and EVO, barring any last second renaming by Samsung. Originally we were expecting Samsung to add a 1TB SKU to their 950 PRO line, but it appears they have changed gears and will now shift their 48-layer parts to the 960 series. The other big bonus here is that we should also be getting an EVO, which would mark Samsung's first retail M.2 PCIe 3.0 x4 part sporting TLC flash. That product should come in a lot closer to 850 EVO pricing, but offer significantly greater performance over the faster interface. While we don't have specs on these upcoming products, the safe bet is that they will come in very close (if not identical) to that of the aforementioned SM961 and PM961.


Samsung's 48-Layer V-NAND, dissected by TechInsights
(Similar analysis on 32-Layer V-NAND here)

All of these upcoming products are based on Samsung's 48-layer V-NAND. Announced late last year, this flash has measurably reduced latency (thanks to our exclusive Latency Percentile testing) as compared to the older 32-layer parts. Given the performance improvements noted above, it seems that even more can be extracted from this new flash when connected to a sufficiently performant controller. Previous controllers may have been channel bandwidth limited on the newest flash, where Polaris can likely open up the interface to higher speed grades.

We await these upcoming launches with baited breath. It's nice to see these parts inching closer to the saturation point of quad lane PCIe 3.0. Naturally there will be more to follow here, so stay tuned!

Drobo Updates 5D to Turbo Edition 5Dt

Subject: Storage | June 21, 2016 - 02:43 PM |
Tagged: usb 3.0, Thunderbolt 2, raid, hdd, drobo, DAS, BeyondRAID, 5Dt, 5D

Today Drobo updated their 5D, shifting to Thunderbolt 2, an included mSATA caching SSD, and faster internals:


The new 5Dt (t for Turbo Edition) builds on the strengths of the 5D, which launched three years ago. The distinguishing features remain the same, as this is still a 5-bay model with USB 3.0, but the processor has been upgraded, as well as the USB 3.0 chipset, which was a bit finicky with some earlier implementations of the technology.


The changes present themselves at the rear, as we now have a pair of Thunderbolt 2 (20 Gb/s) ports which support display pass-through (up to 4k). Rates speeds climb to 540 MB/s read and 250 MB/s write when using HDDs. SSDs bump those figures up to 545 / 285 MB/s, respectively.


Another feature that has remained was their Hot Data Cache technology, but while the mSATA part was optional on the 5D, a 128GB unit comes standard and pre-installed on the 5Dt.

The Drobo 5Dt is available today starting at $899. That price is a premium over the 5D, but the increased performance specs, included SSD, and Thunderbolt connectivity come at a price.

SK Hynix jumps into Enterprise SSDs with the SE3010

SK Hynix's SE3010 uses their own controller, the eight channel SH87910AA Pearl and in the case of the 960GB model, eight 16nm 128Gb MLC NAND chips with a mysterious H27Q18YEB9a label and four capacitors to prevent data loss in the case of unexpected power loss.  The drive is optimized for read speeds and Kitguru's testing certainly shows that they were effective in their implementation.  Check out the write speed and overall conclusions in the full review.


"When we last looked at an SSD from SK hynix it was from their consumer portfolio. This time around we are looking at a drive from the other part of their storage business in the shape of the SE3010, a read intensive drive for the Enterprise market space."

Leaked Intel Roadmap Details Upcoming Optane XPoint SSDs and Storage Accelerators

Subject: Storage | June 13, 2016 - 03:46 AM |
Tagged: XPoint, tlc, Stony Beach, ssd, pcie, Optane, NVMe, mlc, Mansion Beach, M.2, kaby lake, Intel, imft, Brighton Beach, 3DNAND, 3d nand

A recent post over at included a slide of some significant interest to those who have been drooling over XPoint technology:


For those unaware, XPoint (spoken 'cross-point') is a new type of storage technology that is persistent like NAND Flash but with speeds closer to that of RAM. Intel's brand name for devices implementing XPoint are called Optane.

Starting at the bottom of the slide, we see a new 'System Acceleration' segment with a 'Stony Beach PCIe/NVMe m.2 System Accelerator'. This is likely a new take on Larson Creek, which was a 20GB SLC SSD launched in 2011. This small yet very fast SLC flash was tied into the storage subsystem via Intel's Rapid Storage Technology and acted as a caching tier for HDDs, which comprised most of the storage market at that time. Since Optane excels at random access, even a PCIe 3.0 x2 part could outmaneuver the fastest available NAND, meaning these new System Accelerators could act as a caching tier for Flash-based SSDs or even HDDs. These accelerators can also be good for boosting the performance of mobile products, potentially enabling the use of cheaper / lower performing Flash / HDD for bulk storage.


Skipping past the mainstream parts for now, enthusiasts can expect to see Brighton Beach and Mansion Beach, which are Optane SSDs linked via PCIe 3x2 or x4, respectively. Not just accelerators, these products should have considerably more storage capacity, which may bring costs fairly high unless either XPoint production is very efficient or if there is also NAND Flash present on those parts for bulk storage (think XPoint cache for NAND Flash all in one product).

We're not sure if or how the recent delays to Kaby Lake will impact the other blocks on the above slide, but we do know that many of the other blocks present are on-track. The SSD 540s and 5400s were in fact announced in Q2, and are Intel's first shipping products using IMFT 3D NAND. Parts not yet seen announced are the Pro 6000p and 600p, which are long overdue m.2 SSDs that may compete against Samsung's 950 Pro. Do note that those are marked as TLC products (purple), though I suspect they may actually be a hybrid TLC+SLC cache solution.


Going further out on the timeline we naturally see refreshes to all of the Optane parts, but we also see the first mention of second-generation IMFT 3DNAND. As I hinted at in an article back in February, second-gen 3D NAND will very likely *double* the per-die capacity to 512Gbit (64GB) for MLC and 768Gbit (96GB) for TLC. While die counts will be cut in half for a given total SSD capacity, speed reductions will be partially mitigated by this flash having at least four planes per die (most previous flash was double-plane). A plane is an effective partitioning of flash within the die, with each section having its own buffer. Each plane can perform erase/program/read operations independently, and for operations where the Flash is more limiting than the interface (writes), doubling the number of planes also doubles the throughput. In short, doubling planes roughly negates the speed drop caused by halving the die count on an SSD (until you reach the point where controller-to-NAND channels become the bottleneck, of course).


IMFT XPoint Die shot I caught at the Intel / Micron launch event.

Well, that's all I have for now. I'm excited to see that XPoint is making its way into consumer products (and Storage Accelerators) within the next year's time. I certainly look forward to testing these products, and I hope to show them running faster than they did back at that IDF demo...

OCZ and NVMe all up in the RD ... 400

With all the new drives on the market it would be interesting to see The Tech Report try to kill another stack of SSDs.  With the spread of NVMe drives they could take the OCZ RD400 they just reviewed and a number of others and see if they can't write them to death.  It would likely be a bit more work, these drives are more resilient and the amount of data they can move in a short time would certainly require a change in methodology.  The Intel 750 and Samsung 950 Pro would be obvious choices as most other SSDs simply would not be able to keep up.  Al has a collection as well, maybe a joint effort to kill as many PCIe SSDs as possible?


"Toshiba is bringing the OCZ brand into the NVMe SSD market with its RD400. We put the drive through its paces to see how it stacks up with Intel's 750 Series and Samsung's 950 Pro drives."

Intel Adds M.2 Adapter Option to SSD 750 Series

Back when Intel launched their SSD 750 Series product line, their hope was that the motherboard industry would adopt the U.2 PCIe connector and add those ports to all motherboards. Well, it's over a year later, and we've only seen U.2 appear on a very small fraction of currently shipping motherboards. It's far more likely to see motherboard manufacturers simply tossing in a U.2 to M.2 adapter than to incorporate both onto the board itself. Since things have panned out the way that they have, Intel has recently let us know they will be introducing a new SKU of the SSD 750 products:

Photo Jun 07, 14 09 50.jpg

Instead of the bundled U.2 cable (seen above next to an ASUS Hyper Kit), the alternate will include a U.2 to M.2 cable, eliminating the need for an adapter for consumers who have no native U.2 port on their systems.

For now, the only available products on the market have the U.2 cable, so don't worry about getting the wrong one. Once the new SKU hits the to market, we should see product descriptions indicating which cable is included. Those purchasing starting this summer should be aware that in the future there will be an additional product with the alternate cable, and be careful to purchase the desired product/cable.

Computex 2016: Corsair Announces Neutron XTI SSDs

Tagged: ssd, corsair, neutron, neutron xti, Neutron XT

Corsair announced a new line of SSDs at Computex. We didn't have boots on the ground there this year, and it's not yet on Corsair's website, so we needed to go with Tom's coverage of the product. The Corsair Neutron XTI uses Toshiba's 15nm MLC flash and the Phison S10 controller “with expanded cache”. This added cache addresses some “performance consistency” issues that Corsair identified, but they didn't seem to elaborate on what that is. It is rated at up to 100,000 IOPS Read and 90,000 IOPS Write, but that obviously needs to be tested to specify when, how, and how often.


Image Credit: Tom's Hardware

Speaking of tested Corsair Neutron SSDs, Allyn reviewed the previous model, the Corsair Neutron XT, all the way back in November, 2014. He was impressed with the drive at the time, although, while it was super fast at low queue depths of about ~1-4 items, it slowed down above that. Since that time, he has been developing some interesting testing methods to figure out whether slowdowns could be related to individual hitches that would be lost in benchmarks that aggregate results and implicitly average them out. He didn't have those methods back then, though, so it's unclear whether the queue depth issue was a symptom of a latency problem, and whether the “expanded cache” will help that.

We'll see when it's launched. It will be available in 240, 480, and 960 GB varieties.

MyDigitalSSD's 480GB Bullet Proof 5 Eco M.2 is indeed available for $130 with the 240 and 120GB models also sporting attractive pricing.  The M.2 drive uses Toshiba TLC memory with decent overprovisioning, an eight channel Phison PS3110-S10C controller and an additional chip which The SSD Review believes is an 8GB SLC cache from Kingston.  The drive tops out the bandwidth of SATA 6Gbps in most tests, offering a very good value for your money.  Even with the shorter lifespan of TLC there is a three year warranty which should cover you until your next upgrade.


"On the test bench today, we have the MyDigitalSSD Bullet Proof 5 Eco M.2 480GB SATA 3 SSD and this SSD just may be the best value available for the dollar right now at $129.99. To think that this little SSD is just shy of that .25/GB mark is incredible…but can it perform?"

Seagate Begins Volume Shipment of 10TB Helium-Filled Enterprise Capacity 3.5" HDD

Subject: Storage | April 29, 2016 - 01:36 PM |

We’ve seen a ramp up of Helium filled-hard drives lately, first with HGST, and more recently with Western Digital Red 8TB and Gold 8TB. It seems Seagate also wants in on the fun:


This drive was initially paper-launched back in January, but now Seagate claims it is shipping in volume. While that original release and today’s update both lack performance specs, there are a few interesting tidbits sprinkled in there:

  • This is a CMR drive, not SMR, meaning that it can be written randomly without any of the batch write penalties of Shingled Magnetic Recording.
  • ‘Advanced write caching capabilities’ hints at a form of the media cache tech present in the HGST He6/He8 and also recently adopted by the WD 8TB Gold.
  • The Seagate 10TB release from earlier this year stated that his model will be a 7-platter design with 14 heads. Helium enables thinner platters, and 7-platter designs began appearing in the HGST He6.
  • At nearly 1.5TB per platter and an assumed spindle speed of 7200 RPM, we can infer that the base specs should be reasonably impressive.

Seagate is not to be outdone by Western Digital and their 8TB Red drive and have released their own 8TB NAS HDD. The model which eTeknix reviewed is designed for SMBs and users that have a huge amount of content they plan to store in the long term.  That results in a 3 year warranty, a limit of 8 drives in a NAS and rated workload of 180TB per year, somewhat less than the Enterprise model, however it is also less expensive.  eTeknix uses a different battery of tests than we do here at PCPer, you can see how the drive is rated in AIDA, Anvil, Crystaldisk and others over in their full review, the numbers are similar to the WD Red drive even with the lack of a rarefied atmosphere.


"Just as you wouldn’t use a low-end graphics card for high-end usage, you shouldn’t use the wrong hard disk drive in your storage system either. There is a reason for every product and you should always pick the one suited for the task at hand, especially when you deal with your storage.

It has been a while since we heard from OWC, over a year since Al saw their offerings at Storage Vision, so it is interesting to see a new PCIe SSD from them.  Their days of Sandforce are over, two SMI 2246 XT 4-channel controllers are paired with a Marvell 9230 RAID controller which allows the four unbranded 256GB MLC flash chips to act as a 1TB RAID 0 drive.  The SSD Reviews found the Macbook Air upgrade drive to run slightly slower than the original 256GB SSD but with quadruple the storage the slight slow down is offset by the extra space.  Check out the Aura drive if you have a Mac in need of upgrade, or if you are simply interested in a tiny 1TB SSD.


"Because of its limited storage capacity and Apples horrendous cost for upgrades, it was very close to being replaced, at least until OWC contacted me a week ago asking if we might like to review their latest 1TB Aura PCIe SSD replacement for mid-2013 and later MacBooks."

DroboAccess Enables SSL Encrypted Remote File Access for Drobo 5N and B810n

Subject: Storage | April 19, 2016 - 05:00 PM |
Tagged: SSL, remote access, NAS, DroboAccess, drobo, B810n, 5N

We are currently testing a round of Drobos here at PC Perspective, and Drobo recently rolled out a new feature that I thought would be better written up as a quick news post. This is a remote access feature that applies to the NAS-style models, specifically the 5N and B810n, and leverages the Drobo Apps capabilities of these devices. If you are a current 5N or B810n owner, you can update your Dashboard application and firmware to unlock this newly announced ‘DroboAccess’ feature.


DroboAccess falls under the ‘myDrobo’ category of Drobo Apps. These are apps developed and supported by Drobo (as opposed to coming from a third party). With Drobo more involved in the end-to-end aspect of this process, they were able to work some additional magic into their implementation:

Drobo Access-42-.png

After a Drobo owner registers their device, they can install any/all of the supported apps (DroboAccess, Koken, and Wordpress). Upon registering, each app prompts for a public URL (a subdomain of Drobo handles the behind-the-scenes registration of a 2k SSL certificate which is installed in the chain, which means that any browser access to the new subdomain is over an SSL (HTTPS) end-to-end encrypted connection. Drobo has set up a relay server that manages incoming internet connections to the 5N or B810n. Home NAT routers are not an issue as the device running the app maintains an outbound link to the same relay server. This eliminates any custom router configurations / port forwarding necessary on the user-side of things, and that free SSL cert keeps prying eyes out of the data coming across the wire. I stepped through this process myself and it was about as simple and seamless as it could possibly be. Once set up, I could browse to (chosen subdomain) from any internet-connected browser and see the files on the B810n:

Drobo Access-45-.png

The interface is similar to what you’d see from other remote access apps (Dropbox, etc). There is also an iPhone and Android app available, but Drobo has chosen to charge $0.99 for this app - an odd choice given the vast majority of remote file access companion apps are free downloads. I spent some time with the iOS app and while functional, I found it a bit clunky in its current form. As an example, sending a photo to DroboAccess from the iOS Share Menu gave an ‘Upload to’ prompt with no ability to choose a destination folder (images were simply dumped in the root, which is *not* mountable on the local network - only subdirectories of root are mountable on the LAN). This means that you would have to log into the Drobo via web browser to access those uploads and move them to shares so they would be visible to local SMB-connected machines.


In testing browser access, I discovered a few more issues:

  • The data throughput rate appears to be capped at 8 Mbps by the myDrobo relay server.
  • Downloading files >2GB failed silently, resulting in a 0-byte file placed on the host.

…so while things are a bit rough around the edges right now, the setup was quick and painless, which was Drobos initial goal for this feature roll out. We’ve fed back our findings thus far, and I suspect the other parts should receive more polish and tweaking over the coming weeks. I’ve include Drobo’s press blast for DroboAccess after the break.

Western Digital Reworks Enterprise Lineup, Launches 8TB Gold Datacenter HDD

Tagged: Xe, western digital, wdc, WD, se, RE, Media Cache, hgst, HelioSeal, gold, 8TB

Western Digital rolled out their Se / Re / Xe branding back in mid-2013. Since that time, a lot has changed in the rapidly evolving enterprise storage industry. SSDs are encroaching into more of the data center rack space out there, and the need for small capacity 10k and 15k RPM drives is dropping substantially in favor of more power efficient (in power and capacity per dollar), larger spinning disks.

With these winds of change comes today’s announcement from Western Digital:


The new Gold lineup appears to be a merging of old and new product lines. The 6TB and below Re series are essentially being absorbed under the new Gold label, but 6TB will no longer be the top capacity offered to WD enterprise customers. A new 8TB capacity will be offered in the form of a HelioSeal drive. The 8TB model will share more parts with the HGST He8 than WD’s previously released 8TB Red, including HGST’s Media Cache architecture, which should yield a nice boost to sustained random write performance over drives lacking this technology.

The press release does not state this, but I suspect WD will be phasing out their Se and Xe product lines over the coming months in favor of Helium-filled drives of the 5400 (Red) and 7200 (Gold) RPM variety. Fewer lines to manage should help them tighten things up a bit and reduce costs even further over time.

We’ll be reviewing the new 8TB Gold just as soon as samples arrive for testing, so stay tuned!

Sony's Optical Disc Archive Storage Reaches 3.3 TB

Sony has developed a higher-capacity version of their Optical Disc Archive (ODA), which now allows up to 3.3 TB of archival storage with the promise of 100-year retention.


Sony ODS-D280U (Image credit: Sony via Computer Base)

Of course the viability of such a system in the next century is unknown, and a working cartridge (which is similar to the multi-CD systems found in cars a few years ago) would be needed to access the data. The idea is certainly interesting considering the potential for failure with traditional hard drives, though hard drives are relatively inexpensive and offer more utility, unlike the write-once Sony ODA cartridges.

For those seeking pure read-only archival storage, the higher capacity of the second-generation Sony ODA at least brings it closer to parity with current hard drive storage.

IDF Shenzhen: Intel Demos 3D XPoint Optane File Copy at 2 GB/s

Subject: Storage | April 14, 2016 - 03:56 PM |
Tagged: Optane, NVMe, Intel, idf

At IDF Shenzhen, Intel talked more about 3D XPoint (spoken cross-point). Initially launched in July of last year, 3D XPoint is essentially a form of phase change memory which has speeds closer to that of DRAM.


It can be addressed at the byte level, unlike flash which transfers in pages (~8KB) and erases in blocks (~6MB). There have been a few demos since the initial launch, and this morning there was another:

Optane demo.png

It is great to see XPoint / Optane technology being demonstrated again, but as far as demos go, this was not the best / fairest example that Intel could have put together. First of all, the 'NAND SSD' they are using is a Thunderbolt 3 connected external, which was clearly bottlenecked badly somewhere else in the chain (when was the last time you saw a 6 Gbit SATA SSD limited to only 283 MB/s?). Also, using SATA for the NAND example while using PCIe x4 NVMe for the Optane example seems a bit extreme to me.

The Optane side of the demo is seen going 1.94 GB/s. That is an impressive figure for sure, but it is important to note that a faster Intel 'NAND SSD' product has already been shipping for over a year:


Yes, the P3700 (reviewed by us here), can reach the speeds seen in this demo, as evidenced by this ATTO run on one of our 1.6TB samples:

Intel DC3700 800GB - atto-4 (driver)--.png

Looking at the P3700 specs, we can see that the 2TB model performs even better and would likely beat the Optane SSD used in today's demo:

P3700 spec.png

Further, in the IDF 2015 demo (where they launched the Optane brand), Intel showed off Optane's random IO performance:


This demo showed 464,300 4K random IOPS, and if you do the math, that works out to 1.9 GB/s *worth of random IO*, which is far more impressive than sequentials that basically match that of the current generation NVMe product of the same form factor and interface.

I'm still happy to see these demos happen, as it means we are absolutely going to see 3D XPoint in our hands sooner than later. That said, I'd also like to see demos that better demonstrate the strengths of the technology, because if today's demo was comparing apples to apples, it would have shown a P3700 matching the speed of Optane, which does not make the previously stated 1000x speed improvement nearly as obvious as it should be presented.

SanDisk have updated their SSD lineup with the X400 family, available in sizes of 128GB, 256GB, 512GB and 1TB all of which are available in 2.5" and M.2 form factors.  They have continued their tradition of adding a small SLC flash cache to the drive, with the majority of storage being TLC.  Inside you will find Marvell's 88SS1074-BSW2 four channel controller and 256MB of DDR3L-1600 and as you can see, a lot of extra space.  SanDisk also united their SSDs lines in the 400, with 256-bit AES on these drives there is unlikely to be a new generation of the 300s.  Check out KitGuru for the full performance numbers of this consumer level SSD.


"The X400 family features SanDisk’s 6th generation 15nm Triple Level Cell TLC NAND and just like the previous X300 uses SanDisk’s nCache technology where some of the NAND runs in SLC mode to bolster performance."
