Powerful CPU, highly configurable; locking drive bays; command line directly accessible via VGA and USB ports.
Not particularly quiet. Expensive.
The QNAP TS-239 Pro reminds us of nothing so much as an easier-to-use version of our
home-rolled FreeNAS server
(January 2010). Unlike most NAS boxes we’ve reviewed, with their little ARM embedded processors and 512MB of RAM, the TS-239 Pro packs a full gigabyte of RAM and a 1.6GHz Intel Atom processor. Furthering the impression that it’s a mini computer is the VGA-out port, which, when combined with a USB keyboard, lets you configure the QNAP’s Linux OS directly. Essentially, the TS-239 Pro is a two-bay Linux home server, with all the features you’d expect from a home or SMB NAS box, from UPnP and iTunes streaming to FTP and web servers—and even some features you wouldn’t necessarily expect, like support for networked cameras.
Like most NAS boxes, the web GUI is the key to configuring and using the TS-239 Pro, and QNAP’s web interface is better than most. The first screen you see when you log in offers wizards for creating groups, users, and shares, and configuring FTP access and backups. A side menu tree offers status, disk and hardware management, and more. System logs and S.M.A.R.T. disk info are easy to find.
