Introduction, Specifications and Packaging
While Western Digital has a huge history with spinning disks, their experience with SSDs has been touch and go. They expanded further into the HDD arena with their very long merging process with HGST, but they have only really dabbled in the solid-state arena. Their earliest attempt was with the Black2 back in 2013, which was a novel concept that never really caught mainstream fame. WD acquired SanDisk a few years back, but they were better known for SD cards and OEM SATA SSDs. More recently we began seeing WD test the waters with PCIe / NVMe parts, with a WD Black and Blue launching at CES 2017. Those were 'ok', but were more of a budget SSD than a powerhouse class-leading product worthy of the Black moniker. Today we see WD take another stab at a WD Black NVMe SSD:
Enter the WD Black NVMe and SanDisk Extreme PRO M.2 NVMe 3D 1TB SSDs. Yes, I know the names are a mouthful, but I would be more worried about the potential for confusion when looking for a WD Black SSD on the market (as there are now two *very* similarly named products). Technically the new part is the 'Western Digital WD Black NVMe SSD'. Yes I know don't tell me - they said Western Digital twice.
We will also be reviewing the SanDisk Extreme PRO M.2 NVMe 3D SSD today. I'm including those results as well, but just as they did with their previous SATA SSD release, these are identical parts with different packaging and labeling. The specs are the same. Heck, the firmware is the same minus the bits that report the device name to the host. For the sake of simplicity, and the fact that the WD part is meant for retail/gamers (SanDisk for creative pros and OEMs), I'll stick with referring mostly to the WD side throughout this review.
Strong specs here. Fast sequentials, but random IOPS is rated at QD32 across 8 threads (QD=256), which is, well, just silly. I know WD is doing this because 'everyone is doing it', and they have to compete, but I have a feeling we will also be seeing very good low QD performance today.
It doesn't get much more no frills than this.

Kingston is continuing its push into NVMe SSDs with its new A1000 series. The budget parts are positioned as mechanical drive alternatives. These drives use a lower cost PCI-E x2 interface and are single sided with the M.2 2280 (80mm) form factor. Kingston is using the four channel Phison E8 PS5008-E8 controller with DRAM cache along with Kingston branded TLC 3D NAND flash (SSD Review's sample reportedly used Toshiba's BICS3 256Gb flash).
The A1000 series (PDF) comes in 240 GB, 480 GB, and 960 GB capacities. They offer up to 1500 MB/s sequential reads across all capacities and the other performance characteristics varying according to the capacity and number of flash dies used. The 960 GB drive is the fastest with up to 1,000 MB/s sequential writes, 120,000 random read IOPS, and 100,000 random write IOPS. The 480GB drive is a bit slower at 900 MB/s sequential writes, 100,000 random read IOPS, and 90,000 random write IOPS. Finally, the lowest capacity 240 GB SSD hits up to 800 MB/s sequential writes, 100,000 random read IOPS, and 80,000 random write IOPS. As far as endurance, Kingston rates all three capacities at the same 1 million hours MTBF and 150 TBW for the 240 GB, 300 TBW for the 480 GB, and 600 TBW for the 960 GB solid state drive. Kingston warranties the drives for five years which is nice to see on a budget drive.
|240 GB||480 GB||960 GB|
|Sequential Read||1,500 MB/s||1,500 MB/s||1,500 MB/s|
|Sequential Write||800 MB/s||900 MB/s||1,000 MB/s|
|Endurance Rating||150 TBW||300 TBW||600 TBW|
Kingston's A1000 SSDs use the NVMe 1.3 protocol but they are limited by the x2 PCI-E interface, especially where reads are concerned. Kingston is pricing the drives at MSRPs of $119.99 for the 240 GB, $219.99 for the 480 GB, and $402.99 for the 960 GB drive which does seem a bit on the pricier side of things but we'll have to wait a bit to see how retail pricing shakes out to say for sure. For example, looking on Amazon, the MSRPs of the A1000 drives are close to the retail pricing of Kingston's faster KC1000 SSDs which makes me think the street prices may come in lower than shown above (hopefully). In any case, the A1000 drives should be available soon as reviews have already begun popping up online.

A month ago, WD and Toshiba each put out releases related to their BiCS 3D Flash memory. WD announced 96 layers (BiCS4) as their next capacity node, while Toshiba announced them reliably storing four bits per cell (QLC).
WD recently did their own press release related to QLC, partially mirroring Toshiba's announcement, but this one had some additional details on capacity per die, as well as stating their associated technology name used for these shifts. TLC was referred to as "X3", and "X4" is the name for their QLC tech as applied to BiCS. The WD release stated that X4 tech, applied to BiCS3, yields 768Gbit (96GB) per die vs. 512Gbit (64GB) per die for X3 (TLC). Bear in mind that while the release (and the math) states this is a 50% increase, moving from TLC to QLC with the same number of cells does only yields a 33% increase, meaning X4 BiCS3 dies need to have additional cells (and footprint) to add that extra 17%.
The release ends by hinting at X4 being applied to BiCS4 in the future, which is definitely exciting. Merging the two recently announced technologies would yield a theoretical 96-layer BiCS4 die, using X4 QLC technology, yielding 1152 Gbit (144GB) per die. A 16 die stack of which would come to 2,304 GB (1.5x the previously stated 1.5TB figure). The 2304 figure might appear incorrect but consider that we are multiplying two 'odd' capacities together (768 Gbit (1.5x512Gbit for TLC) and 96 layers (1.5x64 for X3).
Press blast appears after the break.
