HDTune 2.51

HDTune v2.51


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.

Again we see that the slower interface connection on the Raptor X keeps its burst rate just below that of the SE16, though the Raptor X is slightly faster than the 74 GB Raptor.

The Raptor X has a higher minimum, maximum and average transfer rate in our HDTune test here that translates into a consistently better drive in daily usage.

Also similar as to what we saw in HDTach, the random access time is slightly higher on the Raptor X compared to the 74 GB Raptor though it easily beats the 7200 RPM hard drives.

CPU utilization is higher with the new Raptor X 150 GB model though not by a significant amount in real world terms.
