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.
In CDM we discovered typical SandForce 4K performance with near 40MB/s at one request and that jumped to 65MB/s with QD4.
The same was true with the 4K writes. In this test we recorded 136MB/s with one request and that jumped to 267MB/s with QD4. This test uses incompressible data; we'll look at compressible data later in this review.
