A good update for my DS220+

  • Easy to install
  • Unable to discover

The Synology DS220+ is used to edit the local newspaper. Speed is important then.

Meets expectations

  • You have to push the memory deep enough into the contacts, otherwise it won't work.

Very satisfied

  • Solid device
  • User friendly
  • Easy to install

I had a Synology DS213J, an entry-level model. I have now bought this DS720 plus version, supplemented with 4GB internal memory and 2 x 2TB SSD drive. A breath of fresh air in terms of speed. The apps respond excellently on the NAS. Fast upload and download. Bearing in mind that I have a 200mb fiber optic.
