oh very nice... no warnings on boot, and no warnings while i "dd
if=/dev/sdX of=/dev/null" and i'm seeing 74MB/s+ from each disk on this
simple read test.

for lack of a better test i started an untar/diff stress test on the
disks... we'll see how it goes. (it's based on doug ledford's
memtest.sh)

thanks!
