When HD Tune Pro 3.50 was released in December 2008 it included a brand new Random Access test. 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.
Random Access Read Test Results:
Benchmark Results: When it comes to the random access read performance test the OCZ Vertex EX does very well since it uses the Indilinx controller with 64MB of cache. From the looks of this benchmark the OCZ Vertex EX has very impressive performance numbers as it was able to to 202MB/s in the 1MB file size transfer test.
Random Access Write Test Results:
Benchmark Results: The write performance test results were even more impressive as the OCZ Vertex MLC SSD had an average access time of 0.05-5.5ms and the OCZ Vertex EX SLC averaged between 0.05-4.4ms! The random access write performance results were crazy as the drive was able to have an average speed of 220MB/s.
