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 cached fills. This usually happens only with controllers manufactured by JMicron and Toshiba.
Mechanical drives tend to increase latency when used in RAID, but solid state drives generally don't increase latency. Here we see the Patriot Wildfire keeping the same latency as when we tested a single drive.
The same is true when it comes to write latency. Latency is what makes SSD 'feel' fast when you are opening windows and programs.
