The QNAP TS-451 Turbo NAS is part of a new hardware platform for QNAP that brings a high level of performance to the small tower-based format, at a lower cost than was possible before. The four new TS-x51 towers are being promoted as home-based NAS servers, based on their high performance, low cost, and a bunch of new software functionality that is ideal for the modern home. While recent QNAP launches have leveraged the tremendous potential of 10GbE networking for the business user, the home and the SOHO market aren’t there yet. The home market is very sensitive to pricing, so the best thing to do is to re-engineer the daylights out of the surrounding infrastructure and pump a little more juice into the system controller. More power, new features – lower price? That works for me, usually….

With four 3.5″ drive bays available, there is a potential for 16TB of storage, using readily available NAS-specific drives, plus the ability to link up an expansion chassis through the USB 3.0 ports. If both capacity and redundancy are needed, RAID 5 is usually the minimum configuration. If you want to go to RAID 6 or RAID 10, you need a minimum of four disks, with two spindles completely occupied by providing multiple levels of redundancy for your data. A four-bay device is really the bare minimum for a high availability NAS appliance, and that’s why I think the 4-bay TS-451unit in this series makes a lot of sense for a large majority of users.


Benchmark Reviews has tested a wide array of QNAP NAS products, ranging from the QNAP TS-119 NAS single-disk unit made for home users, to the Goliath QNAP TS-870U-RP 8-Bay NAS for the storage needs of large businesses. Most recently we tested the 4-bay TS-470 powerhouse. Let’s see how this latest Turbo NAS compares to those corporate animals, and to a variety of other siblings and competitors.

    If I’ve read the screenshot of ATTO correcty, you’ve just measured your C drive on SSD 🙂 1Gbit interface is exactly that – 1Gbit = theoretical 125MB/s. With the overhead it will max out on 110-180MB/s which you got in other softwares. I would suggest fixing that part of otherwise great review 😀

    Well, that might explain the very strange results I got….. Thank you so much for pointing that out. I will redo that test and post the true results.

    QNAP suggest 3 possible usb tv tuners for use with this model….namely UPMOST DVB192A HD; Hauppauge Win TV Nova_T Stick (Device: 70019;HW rev DiF4) or Asus My Cinema U3100 Mini. I mistakenly bought a QNAP USB tv Stick when I originally acquired the above unit, thinking that it would naturally be compatible. Some of the above sticks are difficult to either isolate or acquire in UK and I was wondering if anyone else with similar NAS has had any luck with any other usb stick.
