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

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.

Went with the same brand to ensure support for the Synology nas and memory card.

This was a great buy I caught a sale

update: dec’21:

Good, 4 times costlier than Similar product of same quality

Worked as described in my DS220+. Nice to have the additional memory to run more VMs, containers, and full-text search. Went from the stock, soldered 2 GB to at total of 6 GB. I have a pair of 4 TB HDDs running in RAID 1 on this NAS.

Easy to install. Works great in my Synology NAS.

See my Headline

I already purchase one years ago for my DS220 and this one its just as flawless. Will run non stop for years. In addition, you ensure that warranty and support is available since its approved by Synology (of course)

Yep. Its fast.
