What customers say about "Key Specs"
QNAP TS-253PRO Network Attached Storage
  • Excellent NAS with extensive capabilities, high speed and easy installation.
  • Great NAS with 12TB capacity. Would recommend.
  • Two slots of this one, great for me.
  • I used 3.5 drive slots. Great capacity.
  • Excellent upgrade from older model, big size of memory. Excellent storage.
QNAP TS-253A 4G 2-Bay Network Attached Storage
  • I mainly wanted to use it as a Plex/Media Server in RAID 0 with Crashplan providing backup functionality.
  • FWIW, 4k direct play content plays perfectly through my Samsung Smart TV Plex client as being served by the Plex Media Server installed on the NAS.
  • I am extremely impress on how well this NAS function with my iMac.
  • I just love this system. I purchased the least expensive 253a system available (4GB, no HDDs) and bought 8GB of RAM and 2x4TB HDDs separately which saved me several hundred dollars.
  • I do have a 4k TV and I have played back h.264 4k files using the NAS's built-in HDMI outs via the included kodi app (XBMC derivative) and they seem to play back just fine.

What customers say about "Features"
QNAP TS-253PRO Network Attached Storage
  • Very comprehensive feature set and easy to use.
  • It is easy to use and has so many features it is the server that keeps on giving.
  • I use it for automated file and photo backups. Great features.
  • It's powerful, quiet, easy to use, has lots of features and is reasonably priced.
  • Very pleased with comprehensive feature list and performance so far.
QNAP TS-253A 4G 2-Bay Network Attached Storage
  • With this device, there is a ton to investigate and tweak regarding management, diagnostics, etc., especially as a relative NAS-noob (a tech-saavy NAS-noob mind you).
  • But long story short, I couldn't be happier at this point and will update this review in the coming months as I figure more things out.
  • Installation of RAM/HDDs was pretty quick and there are videos on Youtube if you can't figure it out. This system does everything I wanted it to do - Plex media server, basic NAS, running VMs
  • There's so much you can do with this system it's hard to give any reason NOT to go for it if you're in the market for a full-featured NAS.
  • QNAP has removed KODI app from store. One of the main reasons for me buying this unit.

What customers say about "Interfaces"
QNAP TS-253PRO Network Attached Storage
  • Wake on LAN so it goes it a sleep mode and wakes when you try to connect to it. 2 LAN ports.
  • Speed wise it's very quick, the remote access is also very comprehensive.
  • Much faster than my old one. Would recommend.
  • You can run full virtual machines from it. Great speed, really fast.
  • Nice but very, very slow. Very disappointed and let down so far.
QNAP TS-253A 4G 2-Bay Network Attached Storage
  • I highly recommend the Qnap TS-253A as a good storage device and to backup your critical files that needs to be protected.
  • Qnap manufacturer has written in their specs the maximum memory for the TS-253A is 8GB and I can tell you that this is not true. I am currently using 2 x 8GB modules and it functions extremely well.
  • Data transfer is so fast...I'm always surprised. And the system is very quiet...the fan is working but it's whisper quiet.
  • The size makes it portable - I've used it in my RV for weekend trips plugging it in via HDMI for direct playback via the desktop interface.
  • I was hoping to like this a lot more than I have. I am not a computer science major, but I am not entirely computer illiterate either. It wasn't too bad to set up for back-up service, but the other apps are finicky and not as robust as I would hope for the money.
