I have had the Linkstation LS-VL Series 1 TB for many years, it has been a good performer, however, I ready to upgrade to a 2 bay NAS with much larger capacity. I have been reading and heard a lot of good things about Synology. Seems like Buffalo hasn't kept up with a more intuitive interface that runs their NAS systems. I have never been a big fan of the system software or the NAS Navigator programs from Buffalo. Would like others opinion?
