SFS being inferior is just your opinion
Benchmarks are out there, PFS3 is a lot faster than SFS. It's easy to reproduce the fragmentation issue by having multiple apps writing a file on SFS volume at the same time, and to verify the excessive fragmentation that results. Performance deterioration over time is a bit trickier to test, but most likely it's a direct result from the fragmentation issue described, but other factors can be in play as well. The issue has been observed by many (more than just me). Lack of repair tool (for anything but MorphOS) is a fact, too.

It's more than just an opinion.

I've been using it for years, and both of my 500GB HDs are almost full. I've never noticed any performance deterioration or ever had the need to repair any files or partions.
You're extremely lucky.

Benchmarks, smenschmarks, Piru I'm perfectly happy with SFS, never personally experienced any of the issues you described, I was simply just saying that there are other alternative file systems available.

Yup, maybe I am lucky... :)

I'm a satisfied SFS user too, however I am looking forward to testing PFS3 when the "free" version is openly released.

PFS3 is faster than SFS.
 No comparison on my system. PFS destroyed SFS in my SysSpeed tests.

PFS3 doesn't generate massively fragmented files when two or more applications write files to disk. SFS does.
 I can't verify this. SFS is slower and thrashes the HD more with simultaneous writes.  
Quote
PFS3 performance doesn't deteriorate over time. SFS does.
 This is my experience too. I wouldn't consider this is a major issue with SFS.

PFS3 has a repair tool. Often with SFS the only option is to copy data over, reformat and copy data back (MorphOS does have a SFSDoctor tool, however).
 SFS has a recovery tool that works under AmigaOS 3. It's very buggy and slow but I used it to recover a partition. I did have to reformat.
The biggest issue with SFS is bugs.
Can't the mask force the buffer alignment to whatever is needed? I use MASK=0x7FFFFFFC to force longword alignment as that is faster.

I have received various reports from playtesters that SFS has severe problems trying to do 2 or more simultaneous reads.  (even worse if there is a simultaneous read+write).  Supposedly, SFS does not multitask internally.  Maybe some knowledgeable person out there could shed some light on this aspect?

I can still only say, with SFS I have never experienced any of the above mentioned problems...

I must be really lucky... :)

so this may be an incredibly retarded question but if I was to use one of these file systems, how does one go about it?

I am assuming a fresh install would be needed, correct?

Correct !!!

Naw only kidding, You can easily change a partition to SFS, but of course you still need to do a quick format and reinstall. It's well worth the hassle if you use large single files of up to 8GB like I do... :)

You don't need to reinstall. Just backup (for example copy all files to another partition), change file system, quick format and restore the backup.

Someone mentioned in another thread that you need the RDB to contain the "driver" (or whatever it is) in order to boot from the disk too.

That's not specific to the boot partition. Prior to be able to use the file system on any partition, it needs to be added to the RDB.
