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.
This test shows just how inconsistent burst testing an SSD can be, and here’s as good of an example as any. We know octane does way better than 160MB/sec on reads, yet here HDTune gives poor results. For now we’ll just use these as a qualitative cross check between the Patriot drives and other SandForce units.
Slight dips during testing shows the Pyro matching its other IMFT Asynchronous cousin – the Agility 3. Both Patriot drives perform as expected here, easily saturating the SATA 6Gb/sec pipe.
