Qnap TS-559 Pro+: Familiar Network Storage With A New CPU

Features

It’s a good idea to use two CPU cores to speed up multiple drives in RAID 5 or 6 arrays and it’s even better to increase clock speeds. We put Qnap's TS-559 Pro+ with an Atom D525 dual-core CPU to the test: is it any faster than devices with Atom D510?

Conclusion: Higher Speed, Higher Throughput

The Device

In renewing its TS-x59 series and specifically the TS-559 Pro, it was easy for Qnap to avoid mistakes. Take the quality casing and the interior of the previous series, add a mature and proven firmware, and exchange the processor for a newer model running 133 MHz faster. The move is of course evolutionary in nature, and it's a fairly logical step forward. From Qnap's perspective, simply adopting a new processor makes sense; it didn't incur any development costs, and the existing firmware is ambivalent to whether its commands are executed by an Atom D510 or an Atom D525 running slightly quicker. 

The Processor

The remaining question is precisely how much of a benefit is offered by the Intel Atom D525 dual-core processor. Considering the 133 MHz clock speed increase on the TS-559 Pro+, the boost to data transfer rates seems rather low. Quantifiably-higher transfer rates are mainly achieved in RAID 6 operation and where the transfer of data happens sequentially. But if a TS-559 Pro+ replaces a TS-559 Pro in a real-world environment, we'd bet that the difference wouldn't be noticed. Whether or not the processor makes itself evident depends on the application and user profiles; it's too small of a change to impress, though.

Recommendation

Currently, the TS-559 Pro and the faster TS-559 Pro+ are listed on Qnap's Web site. Both devices are also available from online vendors, and a closer look reveals a price difference of about $100 between the two.

Already priced up around $1000 without storage, these five-bay units are expensive. Near-term, users who've been toying with the idea of buying a TS-559 Pro will want to weigh the lower price with slightly lower performance in certain situations. Long-term, though, the TS-559 Pro will likely disappear (it was already deactivated on Newegg's site), only leaving the newer unit. It's 1.8 GHz processor doesn't offer any speed miracles on Windows networks, but a higher clock is always welcome, especially when it comes to the little Atom CPU.

    I remember a time when teh Internet was going to have hyperlinks embedded in articles for clowns like me to look stuff up with.

    C'mon! I'm a knuckle-dragging FPS-player: I don't know what "SMB/CIFS protocols" stands for, let alone good for! Isn't there at lest a related article?

    Ok, I don't get it. Can someone explain to me why this $1000 device that comes with no storage is better than a $500 Linux box you can build yourself that will do everything this does and more plus it will come with tons of storage too...

  • Did you do Gbit Link Aggregation for the tests? Seeing as it has 2 of'em?

    Ease of use. Very few users have the time, will and knowledge to build a NAS.

Linux requires Linux knowledge and you have to provide the software you need yourself - that costs small businesses money. This also offers failover and load balancing with its dual NIC card that you wouldn't have in a $500 Linux box.

    The main thing is ease of installation. You don't need a highly technical person to get this box up and running and quickly backing up your companies data, whereas a Linux machine will require additional staff that a small business normally would not have on hand and have to pay to come onsite.

    For $1000 I'd like one just to play around with myself, though it clearly is not targeted for home users.

    Oops, I meant to write this is better than a $500 Linux box

    I am not aware of any 5 bay hot swap itx case that could be used as a basis for a diy project with comparable functionality. Chenbro can get you to 4 at the cost of no pcie support. No pcie means no esata with a supermicro atom itx board.

    There are ways to go with ATX cases, but that is not really comparable.

    but with that $500 linux box you will force yourself to learn something.. and in the end isn't it all about the pursuit of knowledge! haha well I admin a few linux servers so I'd save the cash and make my own for myself/work instead. On that note if you want I will make them for $999 and free shipping with initial phone setup!!! save a dollar!

    How can you compare them when you are using different hard drives than the earlier tests?

    A NAS is a computer. Heck you can even build a PC put Windows 7/XP Home edition on it and turn it into a NAS all for ~$500 (and thats even with 2tb storage in raid 1, heck that is what I have done and it works great and I am even using a low power AMD CPU that is powerful enough to actually be useful rather than a pathetic atom cpu).

    There is no ease of use factor or amount of time on earth that is worth $500+ dollars.
