What is the best amiga FILE SYSTEM nowadays?

Hi,

I have an A2000 which I've kept pretty much up-to-date as far as possible with the latest OS3.9 and patches.

But I am looking to get any speed boost I can on my hard drive.  I am wondering if there is a better (and up to date) file system than the latest OS3.9 FFS.

I have heard of Professional File System (PFS), which seems to be a commercial product - and I don't know if it's supported anymore.

Also I've heard of Smart File System (SFS) which is free, but I don't know how up-to-date it is?

Is there any file system out there than is better than the lastes "official" Amiga file system (and preferably free)?

Both PFS and SFS have rave reviews on the internet, but most of these rave reviews are old (before OS3.9 was released) so I don't know if they should apply any longer.

How does SFS compare to PFS?  Is one clearly superior?

Okay, question:

Will an improved file system actually speed up file transfers between two drives using the same file system (i.e. SFS)?  Or do these file systems only improve seek times?

Basically I do a lot of work with big audio files and want to be able to load/save/burn them faster than I can right now.
