When we're thinking NAS, we're thinking Terabytes of network attached storage. Fortunately, while LG's N4B1 might be the world's first NAS with integrated Blu-ray recorder, it also supports up to 4TB of disk... with room to grow thanks to 3x USB and 1x e-SATA jacks. LG puts that 50GB of dual-layer, Blu-ray storage to good use by automatically archiving your old data for off-site storage. You do store your data off-site, right?
