It depends just how slow the old drive is...
I wouldn't try it with the oldest working drive I have here - a 30 MB
RLL drive with a _70_ mS average seek time.

It's always worth a try. If it's a WD AC1170, it's specified as having
a "sub 13 mS" average seek, 4 mS track to track, and is 3322 rpm.
This should compare reasonably, as a dedicated swap drive, with a
modern drive with it's 7-10 mS seek and 5000 - 7200 rpm (yes, the data
transfer rate will be about half, but the over-riding factor is
normally the seek time).
