OCZ Vertex 120GB SSD Review

ATTO Disk Benchmark

The ATTO disk benchmark tests the drives read and write speeds using gradually larger size files. For these tests, the ATTO program was set to run from its smallest to largest value (.5KB to 8192KB) and the total length was set to 256MB. The test program then spits out an extrapolated performance figure in megabytes per second.

Read

There is no getting around it, this is a real monster when it comes to shear read speed. However, the Vertex’s performance curve is nowhere near the Intel on the low end and on the high end it's basically the same performance as the Falcon (look for the black dash line just above the Vertex’s Red which signifies the Falcon scores).

Write

Once again we walked away very impressed with the write performance of this drive. As a nice bonus, the write speed is actually slightly better than the Falcon. It is funny but the only real program which showed significant changes in score from 1.1 to 1.3 firmwares was HDTACH and ATTO (we ran this drive and the Falcon with both firmwares). The other programs differences were so slight as to fall into error tolerances.
