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 get our first look at the 4K read performance. The Zalman F1 reads 4K data at nearly 40MB/s, the highest we have recorded on the chart today. The Intel flash doesn't scale as well as the Toshiba Toggle Mode flash on the VisionTek Racer, but the higher the queue depth the less often you will use it.
The Zalman F1 120GB suffers from the same incompressible data brick wall that we observe with all of the SF-2281 drives. The F1 makes it to 171MB/s sequential writes with incompressible data. The 4K writes in this test are nearly 135MB/s.
