I've poked around abit with SFS and I can tell you that there are many pitfalls.
First of all: the docs are not up to date; they reflect the old 1.58 (I think). The ID you want is the one the filesystem list states, not the docs(!).
The identifier have changed several times during devlopment.
And people: you MUST use the update feature in HDToolbox properly when trying to update SFS! Don't just add the new version to the list and start typing the new ID to partitions(!). Click the add/update button, select the old version, click update and click the new version (wherever it's located). Then save changes and you're done. Without data loss(!).
I use a blocksize of 1024 with SFS. It's real fast. However there are people who get serius performance issues and I don't know why.
The file handling benchmark included in the SFS archive says my SFS partitions are about as fast as the RAM disk (filehandling! not transfer rates nor seektimes!).
My best guess so far is that some people may have increased the read-ahead and that cripples performance seriusly. Or they don't add enough buffers to their partitions. Using A500? :-) Who knows?
