They also tend to:
a) be in very controlled environments
b) like not actually being used
c) ignore the first few months (infant syndrome)
d) discount anything after a few years (which is fair enough)
I looked a while ago and found:
- disks ~ 2m hours
- most other stuff (PSUs, memory, motherboards) for 100,000 hours
So how come I have had _way_ more disks fail than anything else (even
taking into account that each box has 2-4 disks I have).
