I see a lot of benefits to using ZFS here. It has transparent
compression, hence improves I/O performance, since RPI USB is very slow
the more you can compress files before writing them to storage the
quicker it will be. Also, many people use USB flash and I suspect
reliability is not as good compared to normal disks, hence ZFS
checksumming is a real bonus.
