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.
Read latency is one of the most important areas we measure in our tests for most users. The lower the latency, the faster your programs launch after you double click.
Write latency isn't as cut and dry. SandForce's architecture doesn't use a DRAM buffer to mask higher write latency that's associated with MLC flash.
