Drive used: Seagate Momentus 7200rpm 320gb drive
Benchmark software used: HD Tune 2.55 and CrystalDiskMark 3.0
First I tested the drive using the backwards compatible USB 2.0 to get a baseline for the drive adapter.
With both sets of benchmarking software I came up with a 29-30 MB/s transfer rate. The solid line across the top in HD Tune tells me that I am saturating the USB 2.0 throughput as opposed to maxing out the drive itself. Next up is the USB 3.0 interface.
In this case the results were a little different between HD Tune and CrystalDiskMark. The HD Tune graph is quite in line with what I have seen on internal drives where the drive itself is maxing out instead of the bandwidth channel. The Patriot Gauntlet USB 3.0 interface provides adequate bandwidth for spinning hard drives.
I wanted to confirm that there were no issues with the adapter, so I reran the same tests on the Vantec USB 3.0 adapter we reviewed a few weeks ago. The results were nearly identical, so it was quite clear the drive itself was maxing out and neither adapter was limiting the transfer speed in any way.
Software was also included for the one-touch backup button on the drive. It installed fine and seemed to be ok, although pretty basic. I never use software like this on my external drives and ended up removing it after testing.
