We only recently had an opportunity to take a closer look at the sister model of the device reviewed in this article. The Qnap TS-559 Pro (without the +) scored well thanks to its quality workmanship, efficiency, reliability, and good data transfer rates. The drawback to fairly well-polished NAS devices is usually their price. The applied to the TS-559 Pro, and it again becomes a discussion point with Qnap's TS-559 Pro+. At launch, it sold for more than $1000, and a quick look online reveals prices that still exceed that four-figure sum. And that's without hard drives, which you'll still need to buy.
Been There, Done That: The Housing
If you're prepared to shell out serious cash for the TS-559 Pro+, you of course expect something in return: mainly, good performance, an attractive housing, and capable software. If you're familiar with this unit's predecessor, the Atom D525-equipped TS-559 Pro+ won't hit you with any visual surprises. As before, Qnap's TS-559 Pro+ is housed in a rugged steel case.
Familiar Layout At The Rear Of The Housing
To be perfectly clear, the TS-559 Pro+ uses the exact same same housing as its predecessor. The dimensions are identical (185 mm height x 210 mm width x 235 mm depth). The same can be said about the connections at the rear of the device. Qnap relies on its tried-and-tested configuration of four USB 2.0 ports, two SATA 3Gb/s interfaces, and two gigabit Ethernet ports. The VGA connection familiar to users of the TS-559 Pro is also available, attributable to the Atom D510 and the Atom D525's integrated graphics unit. That's a cost-saver, since it circumvents the need for a motherboard-down graphics solution.
Ventilation of the TS-559 Pro+'s interior is achieved through a regulated 120 mm fan. A second, smaller fan transports waste heat from the integrated 220 W power supply.
