Different firmware. And spec'ed for 24x7 operation (maybe just tested
better?). I think I remember some timeouts are different so that a drive
will not "hang" an array while it tries to recalibrate or something like
that.
Once I had 8 WD 500G "server level" drives in a raid array. Every once
in a while one would just drop from the array. No reason. Went nuts
trying to figure out what was wrong. A power cycle of the drive and it
would work as new. Ended up being a firmware problem in the drive (!).
WD's response was pathetic. Server drives, consumer drives, I think it
is just a matter of having luck with the right fabrication batch and
firmware - I never buy the latest model.
