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.
You have to scroll down to the middle of the chart to get to the other SandForce based drives in the chart (Intel 520 Series and SanDisk Extreme). Here we really get to see the beauty of the Max IOPS. The 4K and 4 command 4K reads for the three SF-2281 drives are about the same, but when you get to 32 commands, the Max IOPS blows the other 2281 drives away.
Other than the SuperSSpeed Gold Hyper SLC we reviewed a few days ago, the Vertex 3 Max IOPS was the only 120GB SandForce SF-2281 based drive that didn't hit the brick wall when writing incompressible data. The Max IOPS acts more like the 240GB SandForce drives than it does a 120GB.
