The random access read and write test is a very important performance area to look at on solid state drives as some controllers have problems with random writes. In recent years the controllers have improved and the firmware has been better optimized for random read and write performance.
Random Access Read Test Results:
Benchmark Results: When it comes to the random access read performance test the OCZ Vertex 2 100GB SSD with the SandForce 1200 controller in it does pretty well. For example, this drive scored 8607 IOPS in the 4KB test file size.
Random Access Write Test Results:
Benchmark Results: The write performance test results of the OCZ Vertex 2 100GB SSD were better than your average SSD.
