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.
The read latency has increased again since the first release. The first time we tested the 256GB Vertex 4 we recorded .07ms average read latency. The number increased to .11 with 1.4RC and it is now at .12. It's a small increase, but not as dramatic as the last one. Lower access times give you the sensation of going fast when moving around your desktop, opening programs and such.
The write access times held the same on average at .02 just like the other two firmware releases. The spike in latency at the 70% mark is no longer there which is nice to see in the chart and in the benchmark results. You wouldn't see that issue under use, though.
