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.
HDTune's burst test gives inconsistent results. Posted here for information only.
Very consistent 6Gb/sec figures across the board. None of these SSDs have a hard time pegging the fastest SATA speeds.
All SSDs have near negligible access times when compared to the HDD.
