I have been trying SmartFileSystem now for some
month and I like it a lot. Especially when you stack
a larger number of files into one directory, it really
FLIES compared to FFS. I have to admit that once a problem
occured with SFS, when there was a data block it could
not read any more. Since I did know how to deal with it
at first and lacked the time to really care, I ignored it
for some weeks and pressed the "Cancel" button everytime
it occured. This gave me no trouble. According to advice
from the SFS mailinglist, I saved my data to a new partition,
reformatted the old one and used it again. There was pratically
no data loss.
Alltogether, I found SFS fast and much more reliable than FFS.
I would be very glad if it was further developed to be used
with OS4.0.
