We took a look at the performance of the QNAP TS-659 Pro II in the configuration that it is most likely to be used in. It turns out to be a better performer than the LaCie 5big storage server unit that we reviewed last year in the same class.

There are a few quirks in the firmware, particularly with respect to the RAID rebuild. However, none of them are showstoppers. There are a few features such as one touch copy for the USB 3.0 port which could have made more sense for an eSATA port. USB 3.0 is a nice add-on feature, but we are not sure it is worth any additional price premium in the SMB / SOHO NAS market.

QNAP's marketing claims also hold up very well (except for the power consumption numbers which are kept low in the brochures by using 500 GB hard disks, and the rating of the internal PSU, which is 250W instead of the 350W claimed in the marketing brochure). Just like Synology, QNAP also has an exensive wiki system and very helpful forums.

All in all, the Atom D525 based QNAP TS-659 Pro II is the most powerful NAS we have reviewed so far, in terms of raw NASPT benchmark results as well as add-on features (both in terms of hardware as well as firmware). The TS-659 Pro+ has the same hardware specs as the TS-659 Pro II reviewed here (except for the two USB 3.0 ports). If the end-user scenario doesn't involve USB 3.0 devices, the former would turn out to be as good a choice as the TS-659 Pro II.

    the specs on page #1 show 43W max power, but in the SMB, ISCSI and NFS page - you show 72.3W usage - which is it?

    also - why the heck are they using a 350W PSU when only 72.3W max? I could see maybe a 100W PSU which may remove the need for the PSU fan (thereby reducing noise?)

    overall, very tempted to get this device!

    That spec on page #1 is QNAP's claims (and that is with 500 GB hard drives -- mentioned somewhere else). We measured 72.3W and stand by it :)

    Echo your sentiments on the PSU.. And QNAP claims 350 W PSU when the internal PSU is just 250W (not that it matters when the max power consumption is around 70 W only)

    It's sad that a state-of-the-art, $1K+, SMB NAS device still is unreliable when it comes to rebuilds. I stopped using my D-Link DNS-343 (not in the same class as the QNAP) because of all the issues I had with it. Dog slow access speeds, lockups, you name. FW flashes fixed nothing.

    Granted, the web interface is very attractive and it has a lot of high-end features (and the display is nice looking) but when it comes down to brass tacks, data integrity and availability are all that matters. If I can't rely on this device to successfully rebuild after a drive failure, what good is it?

    I built my own NAS (server) out of a mATX mobo/RAM/CPU/HW RAID card I had laying around. I own a copy of Server 2003. I also owned the 5-drive SATA enclosure. Been up for almost 18 months now with a reboot roughly monthly for Windows updates. Zero issues.

    These "shoebox NASs" just aren't ready for prime time. STILL.

    Windows updates? LOL

    What are the effects of going from 1 GB to 3 GB memory? Any better performance? Faster rebuild time? Is there any benefit and if so what are they?

    BTW: like the article I like the fact you took out a drive and made the system rebuild a disk. Most articles I have read just gloss over any real world test and just regurgitate the products propaganda.

    I wonder how well this would work as source of video files from my DNLA complainant TV?

    uPnP media server works fine as a source for your DLNA TV.. But, this one doesn't do transcoding.. so hopefully your TV's DLNA profile is good enough for your videos.
  • jimr1234567890 - Monday, September 19, 2011 - link

    What would be a good one that can effectively handle transcoding then?
  • ganeshts - Monday, September 19, 2011 - link

    I am evaluating something in the ReadyNAS lineup which has Orb inbuilt. This is supposed to have a transcoding engine, but I am yet to test its effectiveness.
  • saiga6360 - Monday, September 19, 2011 - link

    Why transcode at all? Get a proper media player. TV media players are crap.
  • DanNeely - Monday, September 19, 2011 - link

    Even if the box on your TV has enough computational power to play arbitrary modern formats without special purpose hardware low power handheld devices (phones, and tablets) are unlikely to be able to do so any time soon. Over longer terms unless we eventually reach a point where throwing more hardware at the problem stops yielding better quality images for a given file size I don't expect this to change.

    Also the number of playback points you have is also a factor. If you only need to stream to one or two TVs spending an extra hundred bucks per screen for more powerful decode isn't a big deal; if your McMansion has a tv in each of a dozen+ rooms then consolidating all of your transcoding into a single location and using dumb hardware at each TV will save significant amounts of money.
