The old Black SSD simply stigmatized the reputation of Western Digital's black label. This time, the company made a new black disc SSD.
The new black disk follows the M2.2280 specification and the NVME protocol. Own controller And WD 3D flash memory (according to SanDisk 3D NAND granules), has made great progress in terms of performance, power consumption, and durability (the following indicators all refer to the 1TB model):
· Read 3400MB/s sequentially and write 2800MB/s;
· 4K random read 500K IOPS, write 400K IOPS;
· Durability 600TBW;
· Priced at $450 (1TB), $230 (500GB), $120 (250GB), and five-year warranty.
The new Black SSD benchmarked against the Samsung 960PRO, PCWorld magazine under the guidance of the manufacturer's careful application of toy-grade speed measurement software and NVME benchmarking product 960PRO benchmark - TLC challenge MLC, even if the defeat is miserable also can save face:
More in-depth Anandtech tests (More in-depth StorageReview didn't get samples because Western Digital's suspect tests are too enterprise-oriented. StorageReview says okay, but how about you?) But Western Digital did not respond:
Tests show that despite the failure of the new WD Black SSD to challenge the 960PRO, it is in line with its own heirloom MLC product (SanDisk Extreme Pro).
Considering both performance and cost, it is a stubborn (1TB level) to hold MLC in 2018.
In addition to 64-layer 3D NAND particles inherited from SanDisk, the advantages of Western Digital's new SSD are mainly derived from its own controller that provides extreme performance for the BiCS process. Almost all aspects are flawless, except for sleep power:
According to Anandtech, NVMe's deep sleep is inherently difficult to do. Only Samsung and Intel can handle the problem. Western Digital is investigating this issue. In the future, the phenomenon of high standby power consumption may be fixed through firmware upgrades.
Since the standby is not really asleep, the side effect - or unexpected benefit is that the wake-up delay is extremely low:
Another advantage is that the PC thermal pad and all kinds of pull-out heatsinks are still in use. The full-speed NVMe SSD is not top-notch if it doesn't feel like fresh baked sweet potatoes.

Want to buy new black plate please look for SN700The words (SN700 is the product series name), do not confuse with the old black disk.
