You can use bonnie++ to stress test the drives, but it doesn't guarantee
that it uses all of the drive, so you might want to do a massive dd
"dd if=/dev/zero of=/dev/[rawDevice] bs=512 count=[#sectors]" as one
Check with the vendors, though. Many drive manufacturers have utilities
you can download specifically to check their drives.
