CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSDs. We are using V3.0.3. but will be switching to V6.0 shortly so we have added the two CrystalDiskMark 6 result screenshots.
Kingston’s A1000 480GB drive isn’t quite as fast as the last entry-level NVMe drive we looked at, Intel’s SSD 760p, but it is still a relatively quick drive considering its price. The Phison PS5008-E8 controller seems to have a preference for compressible data when it comes to read performance, something which is demonstrated by the slightly different tests run by the older V3.0.3 compared to CrystalDiskMark V6.0.
