CrystalDiskMark is a disk benchmark software that allows us to benchmark 4K and 4K queue depths with accuracy.
* Sequential reads/writes
* Random 4KB/512KB reads/writes
* Text copy
* Change dialog design
* internationalization (i18n)
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.
CDM uses incompressible data so we get our first look at sequential reads and writes with this data type. The SuperSSpeed S301 reads 4K data at 40MB/s, better than anything else on the charts. The S301 also scales very well with a QD4 read of 90MB/s and QD32 at 246MB/s.
Incompressible data writes are usually slower on drives using the SandForce architecture, but the S301 with SLC flash doesn't seem to mind incompressible data. The sequential writes in this test are the second highest on the chart.
