They aren't very good in RAID arrays.  The Western Digital ones
specifically have TLER [1] issue that can cause drives to drop out of
the array.  This can be changed in the firmware, but I still have had
issues since they don't all always keep a consistent spindle speed.

As for general use as a stand alone drive, other than sometimes being
a little slow, I would say they are great.  They are generally some of
the most inexpensive drives, often have large capacities, and make
great second "data" drives.
