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.
Bursts paint the same picture as they did with HDTach.
HDTune does its sequential performance tests using much larger block sizes than HDTach. End result: RevoDrive 3 X2 trounces the field. We saw just shy of 1.6GB/sec in any test allowing it to really stretch its legs.
