Western Digital Announces WD Black PCIe SSD

Western Digital has announced the WD Black PCIe SSD, their first PCIe SSD for the consumer market. While the WD Green and WD Blue SSDs introduced last fall were relatively minor updates to existing SanDisk products, the WD Black is an all-new product. The WD Black is aimed at the cheaper half of the M.2 PCIe SSD market rather than competing for the highest performance: it will be available in 256GB and 512GB capacities for $109 and $199.99 respectively, making it cheaper than any currently available M.2 PCIe SSD except the Intel 600p. The WD Black most likely uses the Marvell 88SS1093 controller and 15nm TLC NAND, a combination that will also be found in Plextor’s upcoming M8Se (albeit with different firmware).

Write endurance ratings are 80 TB and 160 TB for the 256GB and 512GB models respectively, which are the lowest for this product class. On the other hand, the WD Black will carry a 5-year warranty and 1.75M hour MTTF rating.

The WD Black does not appear to include any heatspreaders, but Western Digital’s firmware includes advanced power and thermal management algorithms that WD claims will allow for consistent performance and low power consumption. The WD Black is rated for operating temperatures up to 70°C, so it may engage thermal throttling at a lower temperature than some other PCIe SSD. (For example, the OCZ RD400 throttles around 80°C.)

The WD Black PCIe SSD will be available in the first half of 2017. With this announcement, Micron’s Crucial is now the only major consumer SSD brand that does not have any PCIe SSDs. Last summer Micron abandoned plans for a Balistix TX3 product based on their 3D TLC NAND and Silicon Motion’s SM2260 controller.

PNY Launches CS2030 SSDs: Phison PS5007-E7, MLC NAND, 2.8 GB/s

PNY has introduced its new CS2030 lineup of higher-end SSDs designed for desktops and laptops with M.2-2280 slots. The new drives are based on Phison’s PS5007-E7 controller for PCIe 3.0 x4 SSDs as well as Toshiba’s MLC NAND memory made using 15 nm process technology. The PNY CS2030 are already available in 240 GB and 480 GB configurations.

Like many other companies, PNY does not develop SSDs from the ground up, but uses Phison’s turnkey platforms featuring Toshiba’s NAND flash memory to build its drives, which is why it is not surprising that the PNY CS2030 has a lot in common with other products powered by the PS5007-E7 controller in terms of capabilities (NVMe L1.2 power saving mode, 120-bit/2KB BCH code, end-to-end data path protection, advanced global wear-leveling, etc.). Meanwhile, this does not mean that PNY cannot differentiate from the others by tweaking firmware (or just buying an appropriate firmware from Phison). Apparently, the company opted to lower sequential reads and writes compared to some of the direct rivals (2800 MB/s vs 3000 MB/s, 1550 MB/s vs 2400 MB/s) in a bid to improve random write performance of the PNY CS2030 (up to a rated 300K IOPS).

PNY’s CS2030 family currently consists of 240 GB and 480 GB drives because such capacities are the most popular among customers today. Nonetheless, the company has demonstrated pictures of boxes for 120 GB versions of the CS2030 SSDs, which may indicate that the company is either finalizing the specs of the drives, or plans to sell them exclusively to OEM customers (and/or in certain regions only). As for performance, the PNY CS2030 480 GB has rated sequential read speed of up to 2800 MB/s and sequential write performance of up to 1500 MB/s. The same model of the drive can perform up to 300K random read IOPS (input/output operations per second) as well as 270K random write IOPS. Meanwhile the 240 GB version is rated slightly slower than the top-of-the-range model (see the table for details).

At present, PNY sells its CS2030 in 240 GB and 480 GB configurations for $179.99 and $329.99, respectively, which is in line with prices of some other Phison E7-based SSDs. All PNY’s SSDs come with a three-year warranty.
