So I found the script that was causing the poor performance, but other symptoms have surfaced as well. Sometimes a simple 'ls' on a directory with 30 files will cause the disk to spin for 45 or so seconds while the box is under no other I/O load. Again, no error messages are apparent, and SMART data looks fine.
