Two reasons not to use exFAT on your NAS
I’ve been using the exFAT file system on my Raspberry PI-powered NAS for awhile. I’ve chosen it because exFAT is the only “modern” filesystem that has read-write support in Windows, Linux and OS X. I use all three, so it was beneficial that the drive could be connected to any OS directly over a super-speed USB connection.
