AIDA64 Random Access Time
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.
Access times are what make SSDs feel quick. With ultra low read access times your windows, applications and games open almost instantly. The latest SandForce controllers have a little more latency when compared to the previous generation, but we are talking about thousands of a second here, so you really won't notice.
The write access times for the Vertex 3 are in line with that of the Vertex 2.
