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 cache fills. This usually happens only with controllers manufactured by Jmicron.
The read access times decrease as the capacity increases. This is due to increased interleaving with the higher density flash.
The write latency is the same for the higher capacity Neutron GTX drives. The write latency on the 120GB model is a little erratic since the smaller capacity size has more aggressive background activity. The Samsung 840 120GB and 840 Pro 128GB drives have the same issue.
