Specific models that you're considering would be good. For WD, if you're
referring to the WD's GreenPower (non-RAID Ed), there are 2 gotchas
1) no support for TLER any longer - this IMHO is a deal breaker for RAID
2) ridiculously low sleep times (6s) to maximize power savings - in a
server, this would cause extreme load cycles, however this setting can be
set to less extreme numbers using wdidle.
The main technical criterion for any HDDs to be used in a raid IMO should be
TLER support IMO. Speed/capacity would be secondary concerns.
