I'm seeing read and write speeds of 200MB/sec. I didn't think the disks could even write that fast. Run multiple tests now and checked live stats using iostat.
What drives are these?
I ran a bench on a 7200.10 (or .11?) seagate & new WD Blue yesterday and the WD blue did about 167MB/s while the old seagate was 60MB/s slower. This via the normal onboard sata on a R630 MB. Afterthat I immediately cloned my OS drive over to the WD blue and you can notice the difference.
I'm pretty sure you can get better speeds on performance drives & hardware.
