Anandtech recently posted a review as well. They draw a much more favourable conclusion about the 7200.8
TweakTown also seemed to think that the 7200.8 is a great performer.
Is this drive going to be re-run on TB4 or has it already been? Any indications of how it performs there?
I've seen it reported that the DWU-10A works with the DRU-500A firmware. Has anyone else heard of this or better yet, tried it themselves? The 10A is getting pretty cheap now.
If you want to give it a go you can download the 500A firmware.
