CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0 and v7.

At a deep queue depth of 32, Kingston’s KC2500 sees improvements in performance for both reads and writes over the previous KC2000 drive. Looking at the two CrystalDiskMark result screens it appears that the controller doesn't have a preference for the type of data it's being asked to work with.

At a shallower QD of 1, the KC2500 sees a very small improvement in read performance over the previous KC2000 drive, however, the improvement in write performance is much more impressive.

 

 

 

The latest version of CrystalDiskMark, version 7, 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 results for Sequential read/write performance we could confirm the official Sequential read/write figures of up to 3,500MB/s and 2,900MB/s respectively with the review drive showing reads at 3,527MB/s and 3,009MB/s for writes under testing.
