  The first answer is yes, you can do two 80's and performance should be
somewhat better than one 160 (assuming similar seek times).

  However, running on a ship is going to present lots of motion (roll) and
vibration which are hard on a disk. Under those conditions an IDE drive
(or other 3-1/2 inch) may be better in terms of reliability. I know the
Navy has some data on this, and they recently got a bunch of portables
for on ship use on at least a few ships. Having seen them used in
running 4x4's during an off road rally, I guess they are as good as you
will get.
