Under 1.2, probably not much difference.  Under 1.3, with Fast Filesystem, 
the only real limiting factors are hard drive and controller speeds.  Given
a fast enough controller, you'll get a noticable increase.  When I went from
a 65-or-so millisecond Seagate to an 18ms Quantum, I definitely noticed a
difference.  Also, FFS on a plain Amiga seems just as fast as FFS on a
68020 system (to the user, I never actually tried DiskPerf or anything), so
there's no software getting in the way like in the old filesystem, which
really gets faster with a faster CPU.
