HDTune tests a similar level of features as compared with HDTach, but with a different access pattern. Thus provides us with an additional set of benchmark numbers to compare between storage configurations. Here we can get the minimum, maximum and average transfer rates as well as the burst rates and access times. CPU utilization has proven negligible with modern processing horsepower, and is no longer included.
Much like HDTach, HDTune's burst test gives very inconsistent results. Posted here for information only – the results don't have much in the way of significant meaning.
All SandForce drives did very well here. Even the 30GB model nearly capped out SATA 6Gb/sec, exceeding its rated read speed in the peaks.
