Not the best NAS

Marc PHILIP, B&H Photo
5 July 2014
  • Excerpt: I've read a lot of good comment about the new TS-421 replace the TS-420 but I'm not sure we have the same device in hands. Start for the first time is not easy, interface is not user friendly at all. Slow to start, slow to shut down, clearly this NAS missed memory or the processor is too small to my opinion. If you have the choice and if you can spend more money prefer the TS-470 or TS-470 Pro.
  • Pros: Compact
  • Cons: Noisy, Slow

Good reliable but one problem

S. Griffiths "I.T. Networking Professional", Amazon
10 June 2014
  • Summary: It states its a Gigabyte Device with Dual Ports but I come to find out your looking at 30mbs at best maybe 40mbs on a good day. this is less than 1/2 of what would be considered Gigabit. If network transfers are you goal go with the higher up unit that will do faster network speed. I HATE when vendors claim they have gigabit ports and you spend $1000 to find out the processor cannot handle those speeds. I would have returned it but waited too long.

TS-421, B&H Photo
19 May 2014
  • Excerpt: Exactly as described. Very happy that I purchased it. It does way more than described, many apps and can upload photos directly from your phone! If I could afford it, I would have purchased the next level up with more RAM & faster CPU. That is my only complaint, and not really a complaint..I just couldn't justifying spending that much money. Would be nice to have expansion slots for extra RAM.
  • Pros: Easy Setup, Fast, Quiet
  • Cons: Slow

Entertainment System Storage

Buck, Amazon

  • Summary: Over the years I have collected (bought) well over 600 DVDs. For me, this is the perfect solution. It was easy to set up, even though I did have to get on-line with customer support once. They were very helpful. In addition, tutorials are also available. I have not yet set up mobile devices for the NAS, so have no comment about that issue. The most time consuming part was of coarse converting and uploading my collection.

Very easy to setup, lots of features

VegasMike, B&H Photo

  • Excerpt: I have had this for about 2 weeks now and it was very easy to setup. The myqnapcloud site allows me to access the NAS from anywhere in the world. The apps they provide also allow easy access. I'm very happy with the purchase and I received it much faster than originally quoted, which was about 14 days and I got it in about 3-4 days.
  • Pros: Compact, Easy Setup, Fast, Quiet

Actually fun to work with

Bob, Amazon

  • Summary: This NAS file server is awesome. I've worked with a few other big name brands. The Qnap is the easiest to figure out. I get consistent high speeds on file transfers. The APP-oriented concept is actually fun to use. It makes a boring topic seem more modern and modular. Another plus for me is the external power supply. The power supply is similar to what you might find powering most laptop computers.
