AIDA64 offers several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few, if not the only, that will measure a hard drive's random access times in hundredths of milliseconds, as opposed to tens of milliseconds.
Read latency isn't an issue with the Q Series Pro; the drive holds a steady .18ms at 64KB.
The write latency starts out strong, and then steadily increases. This is similar to what we see on many new SSDs using new lithography flash with a SLC like layer handled by the flash transaction layer.
Here we see the actual run in AIDA64 that shows the graph results. The first 8% of the run shows the low latency, and then the drive's latency increases. This is similar to what we see on the 840 EVO, Extreme II, and other drives with an SLC like flash layer.
