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 in the burst results that the iRAM is near the top, but can’t really flex its muscle here as the limiting factor is the SATA bus.
But with sustained transfer rates we again see the performance gain that Gigabyte’s iRAM can really offer. The variance here is within a single MB/s while the standard mechanical hard drives go as low as 28.3 MB/s.
The results here are again very similar to that of HDTach, with the iRAM having nearly no access time required for random reads. Since the iRAM uses memory modules instead of a mechanical head that must move over a certain spot on a rotating disk, access times are extremely impressive.
And also a repeat result from HDTach, HDTune shows the iRAM having a higher CPU utilization though the 5.5% reported here isn’t too bad at all.
