Hi,
there is a raid 0 and raid controller is Smart Array 64xx (rev 01)
hdparm -tT /dev/cciss/c0d0p2 returns the following
/dev/cciss/c0d0p2: Timing buffer-cache reads: 2660 MB in 2.00 seconds = 1329.92 MB/sec Timing buffered disk reads: 248 MB in 3.00 seconds = 82.55 MB/sec
if i try to hdparm -I /dev/cciss/c0d0 it returns /dev/cciss/c0d0: operation not supported on SCSI disks
