Notwithstanding its respectable age, the ReadyNAS Duo looks good among modern entry-level NASes. It features a high quality of manufacture, supports all popular network protocols, has a high speed of reading, and offers an exclusive X-RAID mode. It can make a good home NAS due to its additional functionality such as an integrated DLNA server and a nice BitTorrent client. It allows installing additional software modules, too. The single serious downside is that its write speed isn’t high.
The RND2000 model is one of the least expensive dual-disk NASes on the market at $250-350. We guess that this combination of price and functionality should be appealing for users who do not need the highest performance possible.
