Anyway, I would like to know if anyone has thoughts as to SFS as i haven't tried this filesystem yet and I know it may be hard to get PFS now. Is SFS better than PFS?
Still, PFS, what a great filesystem 
The fact that more people have experience (good ones at that!) with PFS than SFS might say something to answer your question! :-)
I ran PFS 2 & 3 on both my 4000 and on Frankenthousand. Never had a problem with either one.
For now, I plan to run PFS3 on a spare drive in my AmigaOne for backup purposes, while I evaluate FFS2 on the main drive.
(Oh. . . and no, I am not a beta tester, and don't have OS4 yet. I'm just talking about what I'll do once OS4 arrives. I'm stuck with Linux for now.)
