The QNAP TS-239 Pro is a next generation model based on the Intel Atom platform which includes even more features suited to an office environment (such as iSCSI). This NAS includes two drive bays (providing up to 4TB storage) and the unit size has been reduced substantially to a mere 214x175x115mm.

This little NAS includes a 1.6Ghz atom CPU, 1GB DDRII memory and two gigabit LAN ports which is much more powerful than many competing devices. Not only does this improve the performance of some elements (such as the PHP/MySQL server), but it ensures that a larger number of clients can use the NAS without performance degradation. Similar to other QNAP variants there are 12 primary functions which the NAS unit can perform.
