The QNAP TS-659 Pro+ Turbo NAS
While technically still considered a tower, QNAP's new line has the drives arranged horizontally. On the front is a power button and just below that a USB 2.0 port. There is a button surrounding the USB port and this is used for quick copy. The NAS will copy the contents of your thumb drive and store that data securely on the NAS. This makes for easy flash drive backup.
Also on the front is the large LCD panel that is used to check the status of the NAS as well as configure some of the basic functions.
Here we see the QNAP TS-659 Pro+ with its drive bays removed. What is actually amazing to me is that the NAS components are now to the side of the system and above the drives. The amazing part is they actually fit in that small of a space with the new dual core Atom configuration. This leaves the TS-659 Pro+ with a very small footprint.
The side of the NAS has vents that allow cool clean air to enter the system and keep the components cool.
The back is where all of the real action happens, though. Here we see the dual eSATA, dual gigabit Ethernet, quad USB 2.0 and a VGA port. The power supply is at the top of the NAS and it gets a quiet fan of its own.
In our testing we never heard the QNAP TS-659 Pro+ outside of when it was booting.
QNAP is the only NAS manufacturer that I know of that labels their drive sleds by bay number. This is a very nice feature when rebuilding an array. The QNAP sleds also support 2.5" form factor drives.
