AIDA64 Random Access Time


Version and / or Patch Used: 1.60

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.




Read latency for Extreme II sneaks in lower than the Crucial M500 120GB and on average matches the SuperSSpeed S301 drive with SLC NAND.




When it comes to write latency, we have to preface the test because we are using the second run from the Samsung 840 Pro. In our normal testing order, the 840 Pro produces extremely high write latency, even more than the Crucial M500. The high write latency is what keeps us from recommending the 840 Pro 128GB to any power user who will write a large volume of data to the drive quickly.


That said, the SanDisk Extreme II 120GB manages to keep write latency in check with its tiered storage system.
