here is a clue , i moved away from pfs1,2,3 (latest i used 3 for about 3 years.) to sfs ,
i havent had any problem so far but speed is slower on sfs compared to pfs3 BUT! i changed due to pfs has a tendency to crash! and when it does... it crash so hard that you have to reinstall yer whole partition ;(
there aint any "working" repair tools for pfs , they claim they do...but they only postphone em till later so it can crash you BAAAAAAAAAAAAAD!
i tried the tools on sfs , they work ..but if they will rescue all data in a big crash....i guess time will tell.
nothing really beats FFS but sadly its WAY too slow and the validation quirks are way too annoying (validation error....bleh) and well ofcourse the gb barrier's
