Assuming there's no need to worry about compatibility with older systems, I expect it's always better to use the latest stabile linux file system, which currently seems to be ext4
.
However it seems ext4
isn't much of a change. Wikipedia ext4
article does list 11 main features for ext4
, but as far as I understand most of these don't appear to have any major practical difference to ext3
. The article also discusses a potential data loss caused by delayed allocation, but to my understanding this would happen only in esoteric system crash cases and thus not make any practical difference either.
Is this just a small gradual upgrade without any major differences, or should I be running to convert my ext3
systems into ext4
?
