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, but we see here the P3700 still manages to turn in speeds much closer to its rating.

R4 and P3700 both clean house here, but recall what I said earlier about compressible data. On the next page we'll get to the real meat and potatoes.
