MyDigitalDiscount doesn't seem to have been satisfied with their performance BPX line or their value SBX line, and have now launched a BPX Pro, which looks to carry the budget pricing of the SBX while offering performance *higher* than the original BPX. How much faster is the BPX Pro than the BPX? That's what this review sets to find out, so let's get to it.
With the label peeled back, we find the Phison E12, coupled to Toshiba BiCS3 TLC NAND. PCBs are single sided up to 480GB. 960GB (and 2TB - not in this review) employ a different PCB with additional DRAM and two more flash packages on the flip side.
Today we take a quick look at an update to Toshiba's line of OEM SSDs. The first product to employ 96-layer 3D TLC NAND, the XG6:
I'm going to keep this one brief since this is to be an OEM-only product that is not expected to be available in retail channels. It's good to have some results out there since it will appear in many laptops and may result in the creation of a parallel retail product at some point in the future.
XG6 at the top. XG5 at the bottom. Pretty much identical with the labels removed, the major exception being the flash memory, which is now 96-layer BiCS.
Introduction, Specifications and Packaging
When one thinks of an M.2 SSD, we typically associate that with either a SATA 6GB/s or more recently with a PCIe 3.0 x4 link. The physical interface of M.2 was meant to accommodate future methods of connectivity, but it's easy to overlook the ability to revert back to something like a PCIe 3.0 x2 link. Why take a seemingly backward step on the interface of an SSD? Several reasons actually. Halving the number of lanes makes for a simpler SSD controller design, which lowers cost. Power savings are also a factor, as driving a given twisted pair lane at PCIe 3.0 speeds draws measurable current from the host and therefore adds to the heat production of the SSD controller. We recently saw that a PCIe 3.0 x2 can still turn in respectable performance despite lower bandwidth interface, but how far can we get the price down when pairing that host link with some NAND flash?
Enter the MyDigitalSSD SBX series. Short for Super Boot eXpress, the aim of these parts is to offer a reasonably performant PCIe NVMe SSD at something closer to SATA SSD pricing.
- Physical: M.2 2280 (single sided)
- Controller: Phison E8 (PS5008-E8)
- Capacities: 128GB, 256GB, 512GB, 1TB
- PCIe 3.0 x2, M.2 2280
- Sequential: Up to 1.6/1.3 GB/s (R/W)
- Random: 240K+ / 180K+ IOPS (R/W)
- Weight: 8g
- Power: <5W
The MyDigitalDiscount guys keep things extremely simple with their SSD packaging, which is eaxctly how it should be. It doesn't take much to package and protect an M.2 SSD, and this does the job just fine. They also include a screwdriver and a screw just in case you run into a laptop that came without one installed.

Western Digital launched a few new NVMe SSDs at Mobile World Congress today:
To the left we have the WD PC SN720, a PCIe 3.0 x4 NVMe SSD boasting speeds of up to 3.4GB/s and IOPS up to 500k. Available capacities are 1TB, 512GB, and 256GB. To the right we have the WD PC SN520, a more power efficient variant running on half of the PCIe lanes, and with specs coming in at roughly half of its faster brother. Capacities are also cut in half, with the range dropping to 512GB, 256GB, and 128GB. Interestingly, all capacities are available in three M.2 form factors (2280, 2242, and 2230).
We don't have a specific part number for the controller, but WD told us they are manufactured on a 28nm process, employ 8 NAND channels, and use DDR4 RAM (not DRAMless). The controller is optimized for interfacing with WD (/Toshiba) BiCS NAND flash, meaning these SSDs should prove to be a well integrated solution.
Press blast from WD appears after the break.

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.
