CrystalDiskMark 3.0.1 Results

CrystalDiskMark is an easy-to-run and quick utility to use to gauge a drive’s performance. It measures sequential read and write performance and random read and write speeds of random 4KB, 4KB (queue depth 32) and 512KB data.

We began with CrystalDiskMark and first impressions were very good. Sequential read and write speeds went through the roof as both the Samsung SSD 840 EVO and SSD 840 Pro managed speeds in excess of 1GB/s. These numbers exceed even those from PCIe-based SSDs that we see on notebooks. 512k read and writes saw massive improvements as once again speeds beyond 1GB/s were attained. 4k read speeds saw modest improvements but write speeds were once again in many order of magnitudes faster. Finally, on the intensive 4k, 32 queue depth workload, improvements of over 100% was achieved.
