The QNAP TS-439 has a lot of great features going for it. For a 4
drive NAS device which really is a computer optimized for storage purposes,
it doesn't have a huge footprint. The black front with gun metal aluminum
chassis gives it a very sleek and professional look, definitely meant for
the office or a network, tucked away in a network cabinet. Unlike the TS-809
Pro that I reviewed earlier, the TS-439 comes complete with eSATA ports to
increase your capacity by an additional 2 drives.
