CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0.
In CrystalDiskMark’s QD32 test, the Teamgroup T-Force Cardea Zero Z440 just shades Corsair’s Force MP600 in terms of read performance but falls behind when it comes to writes. Both read and write scores are way behind Patriot’s PCIe Gen 4 drive, the Viper VP4100.
We have just started to test drives with version 7 of CrystalDiskMark.
The latest version of CrystalDiskMark includes a couple of profiles that can be used for testing, Peak Performance and Real World. The result screens for these two profiles not only display MB/s results but also IOPS and latency.
Looking at the Peak Performance profile results for Sequential read/write performance we see that it confirms the official maximum read figure for the T-Force Cardea Zero Z440 of 5,000 MB/s but falls short of the maximum official write figure of 4,400MB/s. However, the fastest read IOPS figure of 636,076 IOPS and write figure of 564,451 IOPS fall way, way short of the official maximum of 750,000 IOPS.
