Zyxel's nsa220 is a versatile network-storage device that does more than let you store and share files across a network. It also offers built-in FTP, HTTP, and BitTorrent download services; acts as a media server and a print server; and features built-in RAID capabilities. Its price-per-gigabyte ratio is off the charts, however. Available through the distribution channel, the unit can be purchased without drives, or with up to 2TB of storage. Our review unit lists for $299.99 and was configured with two Western Digital drives for a total of 410GB of storage, which is expensive considering many new home-NAS drives cost less and offer 1TB of storage.
