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.




Most users, especially mainstream users find that extremely fast file transfers are only a small part of the SSD story. It's not every day that someone wants to move a collection of MP3s from one folder to another, but booting your computer is often an everyday occurrence. This is where the low access times come into play and the one area that makes an SSD a must have item in your machine.


In this test we see the access times have risen a bit when compared to the old Vertex 2. Still, the numbers are in line with the new controllers.




The write access times are what have me scratching my head. Here we see the Ultra a .1ms higher than the Vertex 2 and new Vertex 3. Both the read and write access times are much lower than a mechanical platter drive and you will feel this in your day to day activities.
