Unconditioned

Conditioned

Typically within AIDA64 I see a general rise in the random read performance as the drive volume fills, however in the case of the SP920 what we see is the opposite. Whilst this may appear to show a poor performing drive, the results on the following pages will prove to you otherwise.

Drive Comparison

For the purpose of drive comparison I use the performance figures from both unconditioned and conditioned tests with 0% data fill.

Recording the random read speed of each drive that I review is only a recent addition to the testing process so there are only a small handful of drives to compare this to. The key factor to note from above is that the random read performance does improve, albeit slightly, over time.
