Hi Joel, Thanks for the report.
I ca add though: If you use mdadm instead dmraid to access your NATIVE fakeraid (without a linux software raid) you get actually the same results :) hdparm -tT /dev/md0 /dev/md126: Timing cached reads: 9010 MB in 2.00 seconds = 4506.74 MB/sec Timing buffered disk reads: 1498 MB in 3.00 seconds = 498.81 MB/sec And a little side remark: For all I know: mdadm is also favored by intel going forward over dmraid - but ubuntu still favors dmraid by default (I think).
