As with the random read performance, we couldn't get close to the maximum write IOPS figure of 650,000 IOPS with our 4 threaded write tests, the fastest we saw was 184,572 IOPS at QD2. The fastest write IOPS figure we saw from the drive during testing was the 622,990 IOPS (QD32 16 threads) result from the CrystalDiskMark 7 Peak Performance profile test, but even this figure is short of the official maximum of 650,000 IOPS.
4K Random Write v QD Performance
At QDs 1 and 2, the Viper VPR100 holds the advantage over the Viper VPN100 in our random write test, but at QDs 4 and 32 the positions change and it's the VPN100 that holds the advantage.
