Western Digital Black PCIe Gen3x4 NVMe 512GB SSD Review

Futuremark’s PCMark 8 is a very good all-around system benchmark but it’s Storage Consistency Test takes it to whole new level when testing SSD drives. It runs through four phases; Preconditioning, Degradation, Steady State, Recovery and finally Clean Up. During the Degradation, Steady State and Recovery phases it runs performance tests using the 10 software programs that form the backbone of PCMark 8; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint, Word, Battlefield 3 and World of Warcraft. With some 18 phases of testing, this test can take many hours to run.

Preconditioning
The drive is written sequentially through up to the reported capacity with random data, write size of 256 × 512 = 131,072 bytes.
This is done twice.
Degradation
Run writes of random size between 8 × 512 and 2048 × 512 bytes on random offsets for 10 minutes. It then runs a performance test. These two actions are then repeated 8 times and on each pass the duration of random writes is increased by 5 minutes.
Steady State
Run writes of random size between 8 × 512 and 2048 × 512 bytes on random offsets for final duration achieved in degradation phase. A performance test is then run. These actions are then re-run five times.
Recovery
The drive is idled for 5 minutes. Then a performance test is run. These actions are then repeated five times.
Clean Up
The drive is written through sequentially up to the reported capacity with zero data, write size of 256 × 512 = 131,072 bytes.



WD’s Black PCIe drive is pretty constant during the degrade and steady state parts of PCMark 8 Consistency test with a slight performance peak in the last degradation run. The drive recovers from the ordeal well, showing a good deal of consistency through the last phases of the recovery cycle.

  • Theyd better be pretty cheap then! I was expecting something somewhere upwards of 200k iops on both read and write… and upwards of 1gb/s on write too…
