Four SATA bays is better than two, I’d say, and so the Lanner NS04-3100 already has something over the QNAP TS-209 reviewed earlier (and, they even share the same hokey naming schemes). And, it looks like it will compete fairly well on features, as well, with Wi-Fi, iTunes server, UPnP AV media server, DLNA, and support for all meaningful RAID configurations and JBOD. Looks like the NAS server market is becoming enticingly competitive. Pricing and availability information is pending.
