The next software we used was the ATTO Disk Benchmark. The tool measures storage systems performance with various transfer sizes and test lengths for reads and writes. The benchmark performs file transfers ranging from 0.5 KB to 8192 KB. ATTO can be adjusted to do overlapped I/O, in a variety of queue depths. We tested the SSD using the benchmark's default settings, using 256KB file length performance and QD4. ATTO probably gives the most accurate results for compressible read and write data.

Below you see a comparison of the performances of some SSD's compared to the OCZ RevoDrive 3 120GB. The PCIE SSD does not excel when it reads or writes small 4K files:

On the other hand, the RevoDrive 3 120GB destroy the rest of the competition once the file sizes increase (>16KB). The drive gave the expected performance with an average more than 840MB/s for write and more than 1.10 GB/s for read , with files larger than 256 KB, in Queue Depth 4. Setting Queue Depth 10 would further demonstrate the drive's strengths, so feel free to test it if you own or plan to purchase this drive:
