Introduction, Specifications and Packaging
In recent years, Plextor has branched beyond their renowned lines of optical storage devices, and into the realm of SSDs. They have done fairly well so far, treading carefully on their selection of controllers and form factors. Their most recent offerings include the M6S and M6M (reviewed here), and are based on Marvell controllers coupled with Toshiba flash. Given that the most recent Marvell controllers are also available in a PCIe variant, Plextor also chose to offer their M6 series in PCIe half height and M.2 form factor. These last two offerings are not simply SATA SSDs bridged over to PCIe, they are natively PCIe 2.0 x2 (1 GB/s), which gives a nice boost over the current SATA limit of 6Gb/sec (600 MB/sec). Today we are going to kill two birds with one stone by evaluating the half-height PCIe version:
As you can see, this is nothing more than the M.2 version on a Plextor branded interposer board. All results of this review should be identical to the bare M.2 unit plugged into a PCIe 2.0 x2 capable M.2 port on either a motherboard or mobile device. Note that those devices need to support the 2280 form factor, which is 80mm in length.
Here's the M.2 version installed on an ASUS X99-Deluxe, as tested by Morry.

Since we reviewed the Intel SSD DC P3700, many of you have been drooling over the idea of an 18-channel NVMe PCIe SSD, even more so given that the P3500 variant was to launch at a $1.50/GB target price. It appears we are getting closer to that release, as the P3500 has been appearing on some web sites in pre-order or out of stock status.
ShopBLT lists the 400GB part at $629 ($1.57/GB), while Antares Pro has an out of stock listing at $611 ($1.53/GB). The other two capacities are available at a similar cost/GB. We were hoping to see an 800GB variant, but it appears Intel has stuck to their initial plan. Here are the part numbers we’ve gathered, for your Googling pleasure:
- 400GB: SSDPEDMX400G401
- 1.2TB: SSDPEDMX012T401
- 2TB: SSDPEDMX020T401
2.5” SFF-8639 (*not SATA*):
- 400GB: SSDPE2MX400G401
- 1.2TB: SSDPE2MX012T401
- 2TB: SSDPE2MX020T401
We did spot a date of December 12th in an Amazon listing, but I wouldn't count that as a solid date, as many of the listings there had errors (like 10 packs for the price of one).
Introduction, Specifications and Packaging
G.Skill is likely better known for their RAM offerings, but they have actually been in the SSD field since the early days. My first SSD RAID was on a pair of G.Skill Flash SSDs. While they were outmaneuvered by the X25-M, they were equipped with SLC flash, and G.Skill offered them at a significantly lower price than the Samsung OEM units they were based on.
Since those early days of flash, G.Skill has introduced a few additional models but has not been known as a major player in the SSD market. That is set to change today, with their introduction of the Phoenix Blade PCIe SSD:
If you're eager to know what is inside or how it works, I'll set your mind at ease with this brief summary. The Phoenix Blade is essentially an OCZ RevoDrive 350, but with beefier specs and improved performance. The same SandForce 2281 controllers and Toshiba flash are used. The difference comes in the form of a smaller form factor (half height vs. full height PCIe), and the type of PCIe to SATA bridge chip used. More on that on the disassembly page.
In conjunction with Dell World, LiteOn has announced their new EP1 M.2 PCIe SSD:
Designed primarily for enterprise workloads and usage, the EP1 sports impressive specs for such a small device. Capacities are 480 and 960GB, random 4k IO is rated at 150k/44k (R/W), sequentials are as high as 1.5GB/sec, and max latencies are in the 30-40 us range (this spec is particularly important for enterprise OLTP / transactional database workloads). Given the enterprise specs, power loss protection is a given (and you can see the capacitors in the upper right of the above photo). Here are the full specs:
It should be noted that larger PCIe-based SSDs are rated for greater than the 1 drive write per day of the EP1, but they are also considerably larger (physically) when compared to the M.2 EP1. As an additional aside, the 960GB capacity is a bit longer than you might have seen so far in the M.2 form factor. While the 480GB model is a familiar 2280 (80mm long), the 960GB model follows the 22110 form factor (110mm long). The idle power consumption seems a bit high, but enterprise devices are typically tuned for instantaneous response over idle wattage.

It's the first day of IDF, so it's only natural that we see a bunch of non-IDF news start pouring out :). I'll kick them off with a few announcements from HGST. First item up is their new SN100 line of PCIe SSDs:
These are NVMe capable PCIe SSDs, available from 800GB to 3.2TB capacities and in (PCI-based - not SATA) 2.5" as well as half-height PCIe cards.
Next up is an expansion of their HelioSeal (Helium filled) drive line:
Through the use of Shingled Magnetic Recording (SMR), HGST can make an even bigger improvement in storage densities. This does not come completely free, as due to the way SMR writes to the disk, it is primarily meant to be a sequential write / random access read storage device. Picture roofing shingles, but for hard drives. The tracks are slightly overlapped as they are written to disk. This increases density greatly, but writting to the middle of a shingled section is not possible without potentially overwriting two shingled tracks simultaneously. Think of it as CD-RW writing, but for hard disks. This tech is primarily geared towards 'cold storage', or data that is not actively being written. Think archival data. The ability to still read that data randomly and on demand makes these drives more appealing than retrieving that same data from tape-based archival methods.
Further details on the above releases is scarce at present, but we will keep you posted on further details as they develop.

At the Flash Memory Summit, Phison has updated their SSD controller lineup with a new quad-core SSD controller.
The PS3110 is capable of handling TLC as well as MLC flash, and the added horsepower lets it push as high as 100k IOPS.
Also seen was an upcoming PS5007 controller, capable of pushing PCIe 3.0 x4 SSDs at 300k IOPS and close to 3GB/sec sequential throughputs. While there were no actual devices on display of this new controller, we did spot the full specs:
Full press blast on the PS3110 appears after the break:

Marvell is notorious for being the first to bring a 6Gb/sec SATA controller to market, and they continue to do very well in that area. Their very capable 88SS9189 controller powers the Crucial MX100 and M550, as well as the ADATA SP920.
Today they have announced a newer controller, the 88SS1093. Despite the confusing numbering, the 88SS1093 has a PCIe 3.0 x4 host interface and will support the full NVMe protocol. The provided specs are on the light side, as performance of this controller will ultimately depend on the speed and parallelism of the attached flash, but its sure to be a decent performer. I suspect it would behave like their SATA part, only no longer bottlenecked by SATA 6Gb/sec speeds.
More to follow as I hope to see this controller in person on the exhibition hall (which opens to press in a few hours). Full press blast after the break.

Apologies as there was no photo to be taken - Marvell had no booth at the exibition space at FMS.
Introduction, Specifications and Packaging
OCZ's RevoDrive series has been around for quite some time. We reviewed the first of the series over four years ago, and they just kept coming after that initial launch.
The full line of (now legacy) Revo / Z-Drive series products.
With the recent acquisition by Toshiba, it was only a matter of time before OCZ revamped the RevoDrive line with their new flash. It just makes sense, as Toshiba can be obtained much more readily (and cheaply) since they are now an in-house source for OCZ. With the Vector 150 and Vertex 460 already driving 19nm Toshiba flash, we now have the RevoDrive 350:
We suspected they might also count this as an update to the Revo line and not just a flash swap, so with a sample to test, let's see what's what!

Tagged: pcie 4.0, pcie, PCI SIG
You know the PCI-SIG might break the pattern with PCIe 5.0, just to mess with us. But for right now, Tom's Hardware seems to have acquired part of the PCIe 4.0 spec and it is expected to get 2 GB/s bandwidth per lane, per direction. This is double the bandwidth of PCIe 3.0, continuing the trend of each major PCIe release doubling bandwidth of the previous major version.
A 16-lane PCIe 4.0-compliant graphics card or storage add-in board (that feels so weird to write...) has a maximum bandwidth of 32 GB/s inbound and 32 GB/s outbound, 64 GB/s total. This is still below GDDR5 bandwidth, but approaching the same order of magnitude. That said, memory bandwidth is the major roadblock for optimizing GPGPU workloads, already. APUs will probably still have an advantage in CPU and GPU tag-teaming tasks, despite their lower compute performance.
According to bit-tech, the spec is expected to arrive with Skylake and its 100-series chipset.

ADATA has been showing off some upcoming products at Computex, and it's all about DRAM.
We'll begin with an upcoming line of PCIe Enterprise/Server SSDs powered by the SandForce SF3700-series controller. We've been waiting for products with the SF3700 controller since January, when ADATA showed a prototype board at CES, and ADATA is now showcasing the controller in the "SR1020" series drives.
The first is a 2TB 2.5" drive, but the interface was not announced (and the sample on the floor appeared to be an empty shell). The listed specs are performance up to 1800MB/s and 150K IOPS, with the drive powered by the SF-3739 controller. Support for both AHCI and NVMe is also listed, along with the usual TRIM, NCQ, and SMART support.
Another 2TB SSD was shown with exactly the same specs as the 2.5" version, but this one is built on the M.2 spec. The drive will connect via 4 lanes of Gen 2 PCI Express. Both drives in ADATA's SR1020 PCIe SSD lineup will be available in capacities from 240GB - 2TB, and retail pricing and availability is forthcoming.
Continuing the DRAM theme, ADATA also showed new DDR4 modules in commodity and enthusiast flavors. Both of the registered DIMMs on display (an ultra-low profile DIMM was also shown) had standard DDR4 specs of 2133MHz at 1.2V, but ADATA also showed some performance DDR4 at their booth.
