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.
Here we're looking at 4K and native command queuing performance. The Extreme has a 4K read speed of 41MB/s while the M3P only hits 35MB/s. The Plextor has a higher 4 and 32 command read speed, though.
One of the most important performance perimeters for SSDs is 4K single command write speed. In this test the SanDisk Extreme delivers nearly 140MB/s, one of the highest we've seen to date. The Plextor hit just over 103MB/s in this same test.
