For anyone interested who doesn't have USB 3.0, I'm getting sustained read and write rates over 180MB/s with a single SATA drive using this Thunderbolt dock. Very handy for 300GB+ photo libraries that used to take me days to backup!
Nope, that was tested with a 3TB Seagate Barracuda. I didn't know they could go that fast either.
Storage Review agrees. Scroll down about 2/3 of the way. The Crystal DiskMark results at the outer platter edge are right at 190MB/s for sequential reads/writes. You can expect about half that at the inner tracks.
That's using Blackmagic Disk Speed Test. I haven't timed a real world backup, but they do appear to be in line with the reported results compared to past backups. My internal drive benches around 90MB/s.
