Patriot Viper VPR100 RGB 1TB SSD Review

With our 4-threaded 4K random read test, the best IOPS figure we saw from the drive was 367,566 IOPS – way, way short of the maximum quoted figure of 700,000 IOPS. A quick test of the drive with 8-threads saw the read figure reach 551,445 IOPS and the only time we saw over 700,000 IOPS was in CrystalDiskMark 7's Peak Performance profile, when the drive produced a figure of 719,491 IOPS at a QD of 32 using 16 threads.

4K Random Read v QD Performance

At all the tested queue depths, the VPR100 shows better random read performance than the VPN100. As both drives use the same controller and Toshiba 3D TLC NAND it must be down to tweaks in the later version of the firmware that the Viper VPR100 uses.
