I'm just going to highlight the importance of knowing which
physical disk is which on your system.

About a year ago I had to replace a hot-swappable disk from an
array, but then realised I had no idea which physical disk it
was as the map of the disks was rather helpfully *inside* the
case. Due to the physical setup, I had no way or removing the
cover without first powering down the server - which defeated
the whole point of paying extra for hot-swap disks.

So yeah, be sure to label your disk bays, but be sure to put
those labels somewhere *useful*.

Useful like on the front of the drive bays ;-)
The Areca cards have a nice function called drive identify that lights up the selected drive's LED. I think the 3ware cards have it too.
