It's become par for the course for us to name QNAP NAS units as being excellent, and the QNAP TS-239 Pro II+ stays the course.
It's a two-bay NAS running off a single core 1.8GHz Atom, with 1GB RAM and a 512MB DOM. There's a generous helping of USB ports — five, to be exact — that can be used for printers, storage, UPS or Wi-Fi dongles (make sure to check the compatibility list). Two eSATA ports offer quicker external storage, and two gigabit Ethernet ports can either exist individually, set to team or offer redundancy. There's a VGA port here, too, should you wish to troubleshoot your NAS yourself.
So far, so solid — as is the NAS itself, which would cause more than a minor concussion if thrown at someone's head.
Despite its size, the TS-239 Pro II+ retains the feature set of its bigger brothers, minus the RAID options that require more than two disks. In fact, the only major differences would be the lack of an LCD status screen, and the external power supply — a fairly meaty brick that's almost as long as the unit itself.
User interface and features
QNAP's UI is well thought out and excellently presented, considering it has to expose so many features. Upon first logging into the web UI, you're greeted with a coverflow-style screen that will take you to Administration, the web server, the web file manager and QNAP support. We've been complaining about this for a while — although it's pretty, it's just another click that's not needed. There's yet another unnecessary click that's enforced, too; if you click on anything other than "Administration", it pops up a dialogue box pointlessly asking you to click on another link.
The thing's huge ... it goes on forever ... and — oh my God — it's full of features!

Once you're in, the cavalcade of features begins: IPv6 support; DDNS; timed hard disk standby; fan control; whitelist/blacklist ACLs; event notification by SMS, email or both; wake on LAN; automated firmware updates; encrypted volumes; iSCSI and virtual disk support; user and group management; network recycle bin support; SMB, AFP, NFS, SNMP and UPnP protocols; FTP and telnet/SSH access; a LAMP web server with virtual host ability; RSYNC, Amazon S3 backup and Time Machine compatibility for backups; and a button on front copies to or from the attached USB stick from or to a predetermined folder on NAS.
Remote access to the NAS is supplied by MyCloudNAS, allowing users to register an x.mycloudnas.com sub-domain in order to access the NAS wherever they desire.
