AIDA64 offers several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.
Drives with only one or two tests displayed in the write test mean that they have failed the test and their Maximum and possibly their Average Scores were very high after the cache fills. This usually happens only with controllers manufactured by JMicron and Toshiba.
In our access time tests we talk a lot about how a SSD feels in your system and why they feel so much faster than standard platter drives. The reason why has to do with the very low access times and the high IOPS.
If I didn't know better I would swear that OCZ built the Vertex 4 and pointed right at TweakTown and said you want a drive that feels fast, well put your money where your keyboard is. The Vertex 4 feels fast - both the 256GB and 512GB models. As we stated previously, we've installed the drives in working systems to figure out if the low queue depth sequential reads had an impact on our day to day activities. What we found in the process was a new understanding of what it means to have a fast computer.
When it comes to the write access time the Vertex 4 blew us away. This test is closely linked with write IOPS performance and as you can see by the .02ms average on both models tested V4 is the best ever in a SATA drive. This was half the write latency of the Plextor M3 Pro and a massive improvement over Vertex 3 and other SandForce based drives.
