Bonnie++ is what we use. You can use IOzone if you like complex charts. hdparm isn't great for this sort of thing. Also, back to the one of the other suggestions - don't use RAID5. If you only have 3 disks, use RAID1 and 1 hotspare. They don't make disks like they used to, and RAID5 and MTBF stats meant that the chance of having a failure during a rebuild is too high. RAID5 is dead to me. RAID10 if you have enough disks, or RAID1 when you don't. and use LVM. It makes for growing/shrinking/chopping much easier. You can't shrink XFS. Be careful shrinking ext3. http://hardware.slashdot.org/hardware/08/10/21/2126252.shtml and don't backup to tape. Buy lots of harddrives, and expect to buy more of them.
