The AS-SSD sequential benchmark, which uses incompressible data for all of its transfers illustrates performance nicely. Controllers that use on-the-fly compression for example will show big drop in sequential write speed when handling incompressible data.

The overall score of AS SSD benchmark is really good, and it indicates that the Neutron GTX 240GB drive is a good performer.

CrystalDiskMark 3.0.2 shows really good performance when dealing with higher queue depths.
