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 write 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.
Access times are what make SSDs 'feel' so fast. With the absence of moving parts SSDs don't have to wait for the data you request to move into position to be read. The Performance 3 RAID pair achieved the exact same read access time as a single 128GB P3.
The write access times were a little lower than the single Performance 3 128GB. Everything is looking really good so far. Let's have a look at some more tests.
