The QNAP TS-659 Pro II
The 659 Pro II is an advanced unit with a lot of features. When the system is up and running your focus is quickly drawn to the LED display that's just behind the dark plastic cover. This display gives you information about your system in the form of status updates.
There are six drive sleds and each has its own locking mechanism. A power button is on the lower left side as is the first USB 3.0 port.
Around the front USB port is a button labelled COPY. With this feature you simply plug in your storage drive, like a thumb drive and the NAS will copy the data to a designated folder.
Vent holes are present on the side of the TS-659 Pro II. This is the motherboard side of the NAS.
Nearly all of the connections are made on the back of the Turbo NAS. Another USB 3.0 port is located on this side as are four additional USB 2.0 ports. The NAS also has dual eSATA and dual Ethernet. Three fans keep the system cool; two larger fans for the HDDs and circuit board components and a smaller fan for the internal power supply.
All of the ports are a good distance apart so you can easily make connections while the system is up and running.
It may seem a bit trivial, but one of my favorite features is that QNAP labels the drive sleds. I take my TS-809 apart every month to clean dust out of the NAS and with the drives being labeled I know where they go back in every time.
Included with the QNAP TS-659 Pro II Turbo NAS are Ethernet cables, a power cable, quick start guide, software disk and screws for mounting both 2.5 and 3.5 form factor drives in the sleds.
