I've since learned that ext4 is more suited for use on SSDs and am considering an upgrade to ext4. I see the procedure on how to convert from ext3 to ext4 on the wiki, and before I proceed would like to know whether there's an advantage to formatting as ext4 from the start as opposed to converting after an ext3 format. In the case that there is a difference, what exactly is sacrificed in choosing one over the other? Regards, -C
