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 time used to be as simple as looking at a drive's rotational speed, but manufacturers have been able to improve the time it takes for data to be ready back through intelligent cache algorithms. Increases in platter density have also helped lower access times. It might not seem like a 2ms improvement is a big deal, but the decrease in time needed to read each block is pretty large.

 

In our tests we observed the 1TB Scorpio Blue deliver a 15.6ms average access time and the 750GB model reading at 17.92.

The intelligent cache system really shows on the write tests. The new 1TB model performed quite a bit better than the older 750GB model.
