What customers say about "Key Specs"
Synology DS216j 2-Bay Desktop Network Attached Storage
  • The default config is to have redundancy at the expense of losing capacity. 2 of my friends have also bought these on my recommendations.
  • Forum advice is squarely in favour of WD 'Red' hard drives; better safe than sorry I say. I found the 'sweet' price vs capacity point to be 3TB.
  • Once you get going and think bigger than just a network storage device the options are limitless and the online community is always building and supporting new features.
  • Love this, I paired with two wd red drives, and obsoleted several hard drives into a single storage solution.
  • Probably the best storage system you can buy for home and small office use.

What customers say about "Features"
Synology DS216j 2-Bay Desktop Network Attached Storage
  • Fitted second disk, let it get on with rebuilding the RAID (on default settings) which took a long time but it all happens in the background and doesn't interfere with normal use.
  • I've gone for a raid config that gives me 16TB of storage but obviously no redundancy.
  • I have 2 3Tb drives running RAID (mirrored), and had I known the full capabilities of this, I'd have wanted 4 drives in there.
  • Now all my eggs are in one basket, I have it setup as a raid, so some peace of mind in that they are backed up each day, User friendly a kid could set it up.
  • A perfect starter NAS, enough CPU power for the average user.

What customers say about "Interfaces"
Synology DS216j 2-Bay Desktop Network Attached Storage
  • Functionally excellent with a well thought out user interface over operating hardware/software with default behaviour matching the vast majority of use cases. Simply outstanding.
  • Great value for money and the admin interface is easy to use. Inserting the drives is also easy.
  • The DSM software has a brilliant, easy to use interface and migrating settings from my old unit was a simple and painless process.
  • This works perfectly, the synology interface is superb and customizable, a number of really useful tools and apps. Perfect!
  • The interface can be a bit confusing but plenty of google help out there. I have not really played with it since standing it up on my network, but no issues so far.
