As with random reads, the maximum random write figure for the drive is 750,000 IOPS. Once again we couldn't get close to this figure with our tests, the best IOPS figure we could get was at a QD of 16 at 193,520 IOPS.
4K Random Write v QD Performance
Compared to the other two PCIe Gen 4 drives, the best random write performance of the T-Force Cardea Zero Z440 comes at QD's 2 and 4 where it is the quickest of the three drives.
