Correct me if I'm wrong, but we would not _have_ to buy 2 73GB
drives. We _could_ buy 1 and have a mis-matched pair that
does not really take advantage of the faster new drive.
(It it probably a better use of Ryan's time if he does not
have to go search for a refurbished drive -- the small
amount of money saved could be worth the Ryan-goodwill-points.)
OT:
Ryan, I've always wondered whether md is naive in it's raid1 IO
and simply does something like use each drive every other
IO, or if it's more clever and looks for an idle/faster
drive. I've got this feeling that VM swap algorithm
is fairly stupid with respect to IO capacity, but maybe
md is smarter. (Idle chit-chat. No need to respond.)
