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.
The high endurance 25nm NAND doesn't suffer from higher latency like what we're seeing on SSDs using 20nm flash.
You can see the increased latency from 20nm flash in the OCZ Vertex 3.20 positioned just under the PNY Prevail Elite on the charts today.
