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.
High sequential numbers make for good marketing but most users notices the extremely fast actions after moving to SSDs. The feeling of fast most noticed comes from the low access times which are what we measure on this page.
The SandForce based drives like SP900 are a little behind those using Marvell controllers, but at these speeds, a few microseconds isn't going to matter much. At the bottom of the chart we see a 600GB VelociRaptor, one of the fastest mechanical drives ever produced for the consumer market. The numbers pretty much speak for themselves - SSDs have a massive advantage over spinners.
The SP900 produces write access time benchmarks in line with other SandForce based drives.
