Average Access Read & Write Time

It is also very interesting to check out the average read/write access time. In our case we are talking about the access time when flash drives are performing random read and write operations on 512Byte blocks. The end values are calculated basing on the results of a 10-minute test to read/write 512-byte data blocks at a request queue of 1.

When we measure average access time during reads all four today’s testing participants from A-Data turned out next to one another on the result diagram. In this case we should just be happy for the manufacturer: they have hardly yielded anything to the performance leader in this test.

As for the average access time during writes, the picture is different and not as rosy anymore as in the previous case. The results of PD15 and PD14 flash drives are the highest (smaller is better in this case, though. The other two solutions found themselves in the middle of the chart: nothing to be upset about, but also nothing to be really proud of.
