Crystalmark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using V3.0.3.
When it comes to dealing with small bity file's at fairly deep queue depths, the KC1000 lags behind a number of the drives we have looked at recently for both reads and writes.
While its write performance is on par with the last Kingston M.2 drive, the non NVMe HyperX Predator, its read performance is much improved.
The Phison PS5007-E7 controller is clearly happier dealing with highly compressible data as can be seen by the jump in read performance in particular, when the drive is tested with the highly compressible data test of CrystalDiskMark.
