QNAP makes nice products, which are typically priced accordingly. We can certainly claim this after reviewing the QNAP TS-669 Pro. It's a powerful NAS with room for six disks running on Intel hardware. It's very comprehensive and fast, but with an average pricetag of £872, it's not for everybody. The QNAP TS-412 is a different beast altogether, with room for four disks and a more reasonable price of £263 that's in the area of the recently tested Thecus N4100EVO.
The chassis is typical QNAP, and that's a compliment, for the most part. Unlike more expensive models, this version is a little more basic. The trays don't have locks, and there also isn't any display. The USB 2.0 port and back up button are still present. On the back there are lots of connectors: three USB 2.0 ports, two gigabit Ethernet ports and two eSATA connectors. The latter is handy if you want to add more storage space to the TS-412.
The TS-412 is positioned between the TS-410 and TS-419P+/TS+419P II. The price difference with the TS-410 is small, but the other two are in a different league. The TS-410 has an 800MHz processor and 256MB of RAM. The TS-412 has the same amount of memory, but with a 1.2GHz processor. The TS-419P+ has twice as much RAM and a 1.6GHz chip. The TS-419P II also has 512MB of RAM and a 2GHz CPU. The last model also has two USB 3.0 connectors, which the others don't.
The TS-419P+ has been almost completely phased out. In our opinion, the TS-412 and the TS-419P II are the most interesting models. The TS-412 costs an average of £263, and the TS-419P II £438. Per disk you pay £66 and £109, respectively, which is a pretty big difference.
QNAP also has more powerful models, such as the TS-439, TS-459 and TS-469. The TS-419P II also has 512MB of RAM and a 2GHz CPU. The last model also has two USB 3.0 connectors, which the others don't have. You can read the rest of QNAP TS-412: entry-level all the way on Hardware.info.
