In this and my previous $dayjob I've had some degree of responsibility
for a range of NetApp filers or similar devices from other vendors with
fiber channel, SCSI and SATA disks in various configurations. The
failure rate of the SATA disks far outweighs the rates of the others.

That said, the way the arrays are put together in many cases the first
evidence of a drive failure is a box arriving from the vendor with a
replacement, or a phone call from their tech support to tell us. Ah, the
joys of enterprise support contracts :)
