If you somehow felt that there was a test that Al missed while reviewing the OCZ RD400 NVMe SSD, then you have a chance for a second look. There are several benchmarks which The SSD Review ran which were not covered and they have a different way of displaying data such as latency but the end results are the same, this drive is up there with the Samsung 950 Pro and Intel 750 Series. Read all about it here.
"With specs that rival the Samsung 950 Pro, a capacity point that nips at the heels of the Intel 750's largest model, and competitive MSRPs, the OCZ RD400 is out for blood. Read on to learn more about this latest enthusiast class NVMe SSD and see how it competes with the best of the best!"

Introduction, Specifications and Packaging
The OCZ RevoDrive has been around for a good long while. We looked at the first ever RevoDrive back in 2010. It was a bold move for the time, as PCIe SSDs were both rare and very expensive at that time. OCZ's innovation was to implement a new VCA RAID controller which kept latencies low and properly scaled with increased Queue Depth. OCZ got a lot of use out of this formula, later expanding to the RevoDrive 3 x2 which expanded to four parallel SSDs, all the way to the enterprise Z-Drive R4 which further expanded that out to eight RAIDed SSDs.
OCZ's RevoDrive lineup circa 2011.
The latter was a monster of an SSD both in physical size and storage capacity. Its performance was also impressive given that it launched five years ago. After being acquired by Toshiba, OCZ re-spun the old VCA-driven SSD one last time in the form of a RevoDrive 350, but it was the same old formula and high-latency SandForce controllers (updated with in-house Toshiba flash). The RevoDrive line needed to ditch that dated tech and move into the world of NVMe, and today it has!
Here is the new 'Toshiba OCZ RD400', branded as such under the recent rebadging that took place on OCZ's site. The Trion 150 and Vertex 180 have also been relabeled as TR150 and VT180. This new RD400 has some significant changes over the previous iterations of that line. The big one is that it is now a lean M.2 part which can come on/with an optional adapter card for those not having an available M.2 slot.

Today Seagate announced that they are production ready on a couple of NVMe PCIe SSD models. These are data-center tailored units that focus on getting as much parallel flash into as small of a space as possible. From engineering drawings, the first appears to be a half height (HHHL) device, communicates over a PCIe 3.0 x8 link, and reaches a claimed 6.7GB/s:
The second model is a bit more interesting for a few reasons. This is a PCIe 3.0 x16 unit (same lane configuration as a high end GPU) that claims 10 GB/s:
10 GB/s, hmm, where have I seen that before? :)
The second image gives away a bit of what may be going on under that heatsink. There appears to be four M.2 form factor SSDs in there, which would imply that it would appear as four separate NVMe devices. This is no big deal for enterprise data applications that can be pointed at multiple physical devices, but that 10 GB/s does start to make more sense (as a combined total) as we know of no single SSD controller capable of that sort of throughput. It took four Intel SSD 750’s for us to reach that same 10 GB/s figure, so it stands to reason that Seagate would use that same trick, only with M.2 SSDs they can fit everything onto a single slot card.
That’s all we have on this release so far, but we may see some real product pics sneak out of the Open Compute Project Summit, running over the next couple of days.
NVMe was a great thing to happen to SSDs. The per-IO reduction in latency and CPU overhead was more than welcome, as PCIe SSDs were previously using the antiquated AHCI protocol, which was a carryover from the SATA HDD days. With NVMe came additional required support in Operating Systems and UEFI BIOS implementations. We did some crazy experiments with arrays of these new devices, but we were initially limited by the lack of native hardware-level RAID support to tie multiple PCIe devices together. The launch of the Z170 chipset saw a remedy to this, by including the ability to tie as many as three PCIe SSDs behind a chipset-configured array. The recent C600 server chipset also saw the addition of RSTe capability, expanding this functionality to enterprise devices like the Intel SSD P3608, which was actually a pair of SSDs on a single PCB.
Most Z170 motherboards have come with one or two M.2 slots, meaning that enthusiasts wanting to employ the 3x PCIe RAID made possible by this new chipset would have to get creative with the use of interposer / adapter boards (or use a combination of PCI and U.2 connected Intel SSD 750s). With the Samsung 950 Pro available, as well as the slew of other M.2 SSDs we saw at CES 2016, it’s safe to say that U.2 is going to push back into the enterprise sector, leaving M.2 as the choice for consumer motherboards moving forward. It was therefore only a matter of time before a triple-M.2 motherboard was launched, and that just recently happened - Behold the Gigabyte Z170X-SOC Force!
This new motherboard sits at the high end of Gigabyte’s lineup, with a water-capable VRM cooler and other premium features. We will be passing this board onto Morry for a full review, but this piece will be focusing on one section in particular:
I have to hand it to Gigabyte for this functional and elegant design choice. The space between the required four full length PCIe slots makes it look like it was chosen to fit M.2 SSDs in-between them. I should also note that it would be possible to use three U.2 adapters linked to three U.2 Intel SSD 750s, but native M.2 devices makes for a significantly more compact and consumer friendly package.
With the test system set up, let’s get right into it, shall we?

That's right, no matter if you run iOS, Linux or Windows if you have an M key style M.2 port the Silverstone ECM20 add-on card will give you both a PCI-e M.2 slot and a SATA 6Gbs M.2 slot. The board itself is a mounting point, no controller but simply a way to transfer data from a PCI-e M.2 card or a mount for a SATA style card, you provide the cable. The simplcity ensures that your transfer speeds will match what you would expect from a native slot as the tests at Benchmark Reviews show. At less than $20 it is a great way to expand your high speed storage capacity.
"The m.2 form factor is becoming popular for SSDs due to its small size, and, in PCI-E guise, superior performance. As our recent test of the Samsung 950 Pro m.2 SSD has shown, PCI-E m.2 SSDs offer performance many times that of the very best SATA SSDs, so if you’re looking for a storage upgrade, m.2 is definitely the way to go."

Introduction, Specifications and Packaging
What's better than an 18-channel NVMe PCIe Datacenter SSD controller in a Half Height Half Length (HHHL) package? *TWO* 18-channel NVMe PCIe Datacenter controllers in a HHHL package! I'm sure words to this effect were uttered in an Intel meeting room some time in the past, because such a device now exists, and is called the SSD DC P3608:
The P3608 is essentially a pair of P3600's glued together on a single PCB, much like how some graphics cards merge a pair of GPUs to act with the performance of a pair of cards combined into a single one:
What is immediately impressive here is that Intel has done this same trick within 1/4 of the space (HHHL compared to a typical graphics card). We can only imagine the potential of a pair of P3600 SSDs, so lets get right into the specs, disassembly, and testing!

Samsung’s new product launching will be called the 950 PRO. This will be an M.2 2280 form factor product running at PCIe 3.0 x4. Equipped with Samsung’s 32-layer V-NAND and using the NVMe protocol enabled by a new UBX controller, the 950 PRO will be capable of up to an impressive 300,000 random read IOPS. Random writes come in at 110,000 IOPS and sequential throughputs are expected to be 2.5 GB/sec reads and 1.5 GB/sec for writes. Available capacities will be 256GB and 512GB.
- 256GB - $199.99 ($0.78/GB)
- 512GB - $349.99 ($0.68/GB)
- 1TB - (early next year with the switch to 48-layer V-NAND)
The 950 PRO will be shipping with a 5-year warranty rated at 200 terabytes written for the 256GB model and 400 TBW for the 512GB. That works out to just over 100GB per day for both capacities.
These hit retail in October and we currently have samples in hand for testing.
(for those curious, both capacities only have components on the front side of the PCB)

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.

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.
I’ve included Silicon Motion’s FMS press blast after the break.
