One thing to keep in mind is statistics. For a single drive by itself |
| 22 |
it hardly matters anymore what you buy. You cannot predict the |
| 23 |
failure. However if you buy multiple identical drives at the same time |
| 24 |
then most likely you will either get all good drives or (possibly) a |
| 25 |
bunch of drives that suffer from similar defects and all start failing |
| 26 |
at the same point in their life cycle. For RAID arrays it's |
| 27 |
measurably best to buy drives that come from different manufacturing |
| 28 |
lots, better from different factories, and maybe even from different |
| 29 |
companies. Then, if a drive fails, assuming the failure is really the |
| 30 |
fault of the drive and not some local issue like power sources or ESD |
| 31 |
events, etc., it's less likely other drives in the box will fail at |
| 32 |
the same time. |
