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.
Marketing folks like to talk about big flashy numbers, so we hear quite a bit about ATTO performance and transfer rates, but SSD's real standout feature is access times. Access times are measured in milliseconds and the lower the access time, the better the user experience is.
The Vertex 3 240GB has a read access time of .15ms on average. It doesn't sound as cool as 550MB/s, but .15 will make your programs open faster than you can even take your finger off of the mouse.
The Vertex 3's write access time is very fast as well. We managed to write data with an average speed of .18ms.
