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.




When you come from a platter drive the first thing you notice is how fast and smooth an SSD feels when doing just about everything. Since SSDs don't use moving parts all of the latency is electrical instead of mechanical. Electrons move at the speed of light, it sounds a bit like science fiction, but your computer also feels like it was teleported from the future. If you are only running a mechanical drive in your computer then your user experience is suffering because of it.




In the read and write latency tests the Intel 520 Series drives on the Z68 chipset match the latency we see on a single drive. The write latency is a little faster than the single drive, so you get a bit of a performance increase when writing small files to the array.
