Great product

  • Easy to install.
  • Quiet
  • Fast

Had to replace my DS214 after 10 years. Disks could be transferred and software installed quickly. It takes a long time before everything is optimized. But you don't look at it. 4 slots, so enough to store.

Just a good NAS

  • Easy upgrade from previous DS
  • price

Purchased to replace my previous DS414j. What can I say. It was as simple as a new phone these days. Transfer the hard drives (the sled they are in was even identical). Then you start up. Had to indicate to me what this was going to be called (same name as the previous one chosen). And then everything was back to how it was, but then a much faster browser interface and years of security arranged again.
