There are many Linux flash filesystems, but Fedora does not support any 
of them.

You're stuck with EXT2/3/4, XFS, ReiserFS, or JFS.

Personally, I'd take XFS and set the "noatime" mount option. XFS caches 
metadata and file data until it is ready to commit, in the least 
obtrusive way. Setting "noatime" will stop Linux from setting the access 
time on every file when its accessed. This will help SSD life. Remember 
though, it's just my personal opinion. You could get the same through 
EXT2/3/4. EXT4 is similar to XFS from what I've read, but it is a brand 
new file system. XFS has had a decade of use (not all good though, I'll 
admit).
