You should check the drive with smartctl.

Yes.. and be sure to go beyond the basic tests.
First off, make sure it's running:
smartctl -s on -A /dev/disk0 ;for each drive, and using the
appropriate /dev/..
Then after, it's accumulated some stats:
smartctl -A /dev/disk0
For a lot of drives, the first line - raw read errors, can be very telling -
anything other than 0, and your disk is failing.
Start-up-time can be telling, if it's increasing.
The thing is, that most drives, except those designed for use in RAID arrays,
mask impending disk failures, by re-reading blocks multiple
times - they often get the data eventually, but your machine keeps getting
slower and slower.
