Synology RAM DDR4-2666 Non-ECC SO-DIMM 4GB (D4NESO-2666-4G)

$90 for a 4GB DDR4 ram chip!

Yep. Its fast.

It works as expected. Easy installation. Follow ESD installation guidelines.

Only purchased to maintain my 920+ warranty even though any other 4gb stick would work fine. Should be 50% of its current cost ($100~).

The extra Ram might speed up your NAS for certain tasks, like video recording.

Easy.

Decided to go with the pricier memory from Synology because I decided the cost savings by choosing another memory chip brand wasnt worth it. I just want something that works perfectly.

Used on my Synology DS220+. Install was a breeze, start up and NAS recognized with no issues. A little pricey but worth it.

Easy to install. Works great in my Synology NAS.

Not much to say. Plug it in, it works, just like it is supposed to. Helps my new Synology be faster than the old one.
