HDTune v4.01 (*Updated*)
HDTune tests a similar level of features that HDTach does, but with a slightly different access pattern and thus can provide 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.
The Corsair F100 minimum speed was a tad lower than the others due to a few very small dips in its output.
It appears OCZ does a bit more tuning above the standard firmware loadout.
Access times were similar to that seen with HDTach.
