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 see the 4K and native command queuing performance of these lower cost, lower capacity drives. This is where we start to see some of the traits that will help us understand what is going on in the real-world tests. The first thing that really sticks out is between the Corsair Force (SF-1200) and the ADATA S396 (SF-2141). The older Force has better NCQ performance while reading data and the S396 seems to hit a wall around 33MB/s at 4K when using incompressible data.
When writing 4K incompressible data the S396 closes the gap on the older Force, but there is still a large speed different.
