8 Lots of good information posted so far. 2 things I think are missed.
9 Recently, Thailand had some very bad flooding. TV showed clips
10 of the manufacturing districts Flooded by more than 20 feet. Many
11 HD manufacturing plants are in that area. Check, if you can the
12 location of the drive's manufacture. But those folks are very
13 smart and probably partially disassembled the drives, shipped them
14 elsewhere, dried them out and re-assembled the parts....

17 Second and most critical:: Temperature. Monitor it and try to minimized
18 thermal cycles on HD (all HD). Sure they will take it, minute differences
19 in the "coefficient of expansion" of metals, allowances is what primarily
20 gives vibration and opportunity to be destructive after many thermal cycles
21 loosen things up a bit. There are numerous tools to monitor and log the
22 temps of drives...... Crappy, or loose (specification) drives will fail
23 faster that better quality drives (statistically). Over ventilation of the
24 chassis or housing containing the drives is always prudent. In a 4 HD bay
25 area, mount no more than (2) HD for best results.
