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 and Toshiba.




The Samsung 840 read access time at 64KB is .06 across the board. This is a very good rating, but we already know the read performance of the 840 is very good.




Write access time is where the 830 stumbled in our testing. We only tested the 128GB model, not by choice, but that's how the cards fell. Samsung reeled the write latency in on the 840. We've tested the 250GB and here is the 500GB capacity size write latency and both do very well in this test. We're working on getting in the smallest capacity size for a review as well.
