I had one SCSI drive running without fail for 13 years (it never 
failed, but 640MB only goes so far), and others (still in active use!) 
for almost as long.  This email will cross a SCSI disk which has been 
running essentially non-stop (good enough for 5 9's) for 9 years

A recent issue of the USENIX magazine includes an article about the 
actual difference between "enterprise" SCSI/FC and "desktop" drives. 
It also includes a number of articles about observed failure rates at 
a number of large sites (including Google).
