The enterprise drives typically have higher tolerances for things like
cycle count, vibration, etc that they experience when they're packed in
together in large arrays. Since Google is doing 2 disks per server
vibration may not be an issue for them. Other suggestions:
1. Buy a drive with a 5 year warranty. You will use it, even with
enterprise grade drives. Failure is inevitable.
