It's going to depend on the size of the files and the block size of the
FFS disk. If you copy a lot of small files from a 1024-byte block FFS
drive to a 16k byte block FFS disk, they will take up at least twice as much
space.
So some combinations of files with FFS settings may take more space than
PFS3, others less.
Isn't the main claim to fame of PFS that if a save is interrupted, it
doesn't perform a time-consuming check of the whole drive? Validating a
drive in case of doubt was a good thing when drives were 40Megs, but
takes too long on a 600 Meg partition containing many thousands of
files.
I suppose this question will get less important when we have operating
systems that don't crash.
