In our throughput tests both read and write performance peak at the end of the test (16MB block mark). Reads peak at 1,840.16MB/s while writes peak at 1,874.15MB/s, both figures are short of the official figures of 2,000MB/s reads and 1,950MB/s writes.
Although the peak read throughput result of 1,840.16MB/s is a little way off the official maximum figure, the 500GB WD Black P40 Game Drive is the second fastest drive we've seen to date when it comes to Sequential reads. Kingston's XS2000 drive sits in the top spot.
When it comes to Sequential writes the WD Black P40 Game Drive is the third fastest we've seen behind Seagate's FireCuda Gaming SSD and WD's own Black P50 Game Drive.
