An IDE drive would do fine and would most likely provide the best compatability.
Simply set the new drive up as slave and clone the drive as patio said - no losses.
Once it is cloned, remove the old drive and keep for pulling apart later.
Set the new one as master and away you go
Then when you have some spare time, pull the old drive apart for the magnets and anything else you want out of there
(it is also fun to see just how fast it actually spins!
)
