QNAP TS-559 Pro review: QNAP TS-559 Pro

Making the firmware more firm

Version 3.3 of the interface brings new features too — the ability to mount ISO files (including UDF formatted, but it won't open DMGs), to understand external drives formatted in HFS+ and can now update firmware automatically.

It also brings something we've been waiting for for a long time — an overhaul of QNAP's Multimedia Station. Built-in Flash, it only really starts showing its colours once you get a mix of video, music and images in there, showing preview thumbnails of images and movies, and allowing you to play them back.

Well, in theory. There's a lot of video formats it simply doesn't like (either by not showing the thumbnail, or simply not showing files such as MKV), and you'll need to use QNAP's interface to re-encode to FLV in order to get web playback. QNAP says transcode, but that's not the case — it's not being done on the fly, and an FLV file is left permanently in its wake.

Image viewing is the big letdown here. Everything is downsampled, without the ability to see the original image at full magnification. While this is obviously done to keep response snappy and downloads small when viewing on the internet, it can create some annoying moments — a 2560x1600 PNG screenshot, for instance, looked like a complete pixelated mess. You can view images in a slideshow with background music too, although we'd recommend just using some client software like Picasa and connecting over SMB, as QNAP doesn't allow full-screen viewing and the transitions are slow.

You can install Cooliris, which provides better results and scales the images smartly, but it's not properly integrated into the Multimedia Station, as it sits in its own tab and it's impossible to browse nested folders, making it nothing more than a trophy effect like Flip 3D was in Windows Vista. To rub it in, you actually have to be online to use this as it loads the interface through

QNAP's iPhone app though is a sure-fire winner — while it will only play video formats the iPhone likes, the ability to pull images from your NAS from anywhere in the world to your iPhone, along with sending photos you've taken back, is a big plus. You can even stream from your music collection, a good solution to overcoming the paltry 32GB of storage on the device. Sadly, there's no Android app yet — we can only cross our fingers and wait.


Copying a large file over SMB netted us an average of 68MB/s to the device, and 76MB/s from it. This isn't the biggest performance we've seen, but then we'd need more RAM and a chunkier processor in order to achieve better. For an Atom-based NAS, this is quite good indeed. We do wonder how it would cope in a multi-user environment though — those who have more than 10 seats in their business or a reliance on high throughput should look for something more powerful. For those who just want raw storage though, the QNAP TS-559 Pro brings it along with an ever-increasing swag of features.
