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.
The reason why SSDs feel so fast when doing day to day tasks like opening browser windows and software packages is due to their extremely low read and write access. Traditional platter drives need to locate the files using two moving parts; the platters and the arms that read the platters. SSDs have no moving parts and can read and write data without the overhead of 'finding' the data.
The Crucial m4 improves upon the Crucial RealSSD C300's read access time by a small margin. The minimum, average and maximum read access times were all uniform at 11 microseconds.
The write access times of the Crucial m4 saw the most improvement, though. Here we found the new Marvell controller with Crucial firmware approaching what OCZ was able to deliver with the Vertex 3.
