Check out the Netgear Storage Central. $150 gets you a 2 bay SAN device that can hold as much as a terrabyte (or more as drive capacities increase), connects seamlessly to your network, and is cross platform. I’ll have one of these by Christmas. The only downside is it’s IDE – I’d prefer SATA since it’s gradually displacing IDE in terms of volume of drives shipped. Still this thing rocks for the price.
