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.
Last week we looked at two 120GB drives based on SandForce controllers and we stated in the 120/128GB capacity size SandForce is losing ground. That obviously doesn't apply to the SuperSSpeed SLC drive and as you can see here it doesn't apply to the 240GB drives either. The 4K read speeds at a single request is still faster than most of the Marvell drives. The SuperSSpeed drive also scales very well, but is a little slower when the commands stack up.
CDM uses incompressible data so this is the first time we see incompressible data and sequential write speeds. The SuperSSpeed S302 delivers a solid 334MB/s, nearly double what the 120GB SF-2281 drives deliver. The 4K single command write speed is 129MB/s which is about average for 240GB drives and in the middle between some of the best Marvell solutions on the market today.
