Testing – ATTO Disk Benchmark & CrystalDiskMark
Next up we have ATTO Disk Benchmark that measures transfer rates across specific lengths.

Very good results here, our best for a SandForce-based drive.  The results were 284MB/s read and 272MB/s write, which is pretty much spot on with the advertised speeds.  CrystalDiskMark is our next test and it has a sequential read / write test as well as a 512k and 4k random read / write test.  Keep in mind that SandForce-based drives usually do score lower in this test.
