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 Crystal Disk Mark we start to see the SP900's asynchronous configuration come into play. This test uses incompressible data (data that is already compressed). For many users the single command 4K read speed that is in line with several other leading SSDs on the market will do just fine. Users who work with media files will want to steer clear of the SP900 because the flash handicaps the performance of these file types.
I was surprised to see the SP900 performing so well in the CDM write test. We've seen several of the asynchronous flash equipped SF drives do poorly here, but that wasn't the case with the SP900. The TRIM issue is starting to come into play at this point as well. The high queue depth numbers are around 15MB/s slower than what we recorded with the Patriot Pyro SE 240GB at this point in our testing cycle.
