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.




When you come from a platter drive the first thing you notice is how fast and smooth an SSD feels when doing just about everything. Since an SSD is without moving parts all of the latency is electrical instead of mechanical. Electrons move at the speed of light, it sounds a bit like science fiction, but your computer also feels like it was teleported from the future. If you are only running a mechanical drive in your computer, your user experience is suffering because of it.


In the read access test we observed an average latency of just .13 milliseconds. That escalated to .15ms at peak so the 510 Series is able to hold a solid latency time while reading data.




Both the read and write access times were very good on the Intel 520 Series. The drive managed to outperform the Vertex 3 240GB in both tests. It appears Intel managed to further optimize latency with their new high performance SSD beyond what we've seen with the standard SandForce firmware.
