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, access times and CPU utilizations.
HDTune doesn’t show the jump that HDTach did, but the 750GB Caviar SE16 is still the fastest drive in the burst category. The transfer rate reported with HDTune is actually showing that the new WD7500AAKS has the top min, max and average speeds. As for the random access and CPU usage charts, the results are basically the same as we saw on the previous page from our HDTach tests.
