How can I physically identify a single drive in a RAID array?

I have a computer with several drives in it, all identical, all part of a RAID. One of those drives is failing (sdc), but I can't tell which physical drive is sdc... any suggestions?

This will output the serial number of the disk, which should be printed on its label:

sudo hdparm -i /dev/sdc
