If you lose your swap partition when it is in an unmountable
state you may well suffer a kernel panic (hard crash). With
drive warranties down to one year I have minimal confidence in
my new drives.
In theory it should also increase performance of reading from
the swap file so performance will depend on what type of use
your swap partition gets. It may be a wash, slow your system
down noticeably, or speed your system up noticeably.
If you really care you need to benchmark it under the loads that
you will put your computer under.
