Lots of storage capacity.

  • HDD Transfer from old NAS very easy
  • Add HDD without turning off NAS
  • Expandable up to 8 HDDs (7+1 in SHR)
  • Sound HDDs - Move NAS far enough

Smooth transfer of the 5 HDDs of 8TB from the DS1520+ to this DS1821+.
Adding 6th disk 8TB disk took 24 hours (from 4x8+8 to 5x8+8). Expected 2 days so very happy with it.

Nice NAS with the right functionalities

Have had the NAS for a week now and it works great. User-friendly interface with just the right amount of options. Great that there are many slots available and that a configuration can be chosen for a combination of different sizes of disks, so that old disks are still usable

Expensive, but then you also have something

  • Fast
  • DSM is reliable
  • Quiet
  • Price

Great NAS for home use with more than enough options. Both software and hardware. I am very satisfied with the purchase

Not cheap, especially considering the meager decoration. Additional parts are expensive
