16GB D4ECSO-2666-16G 260-Pin DDR4-2666 PC4-21300 ECC SODIMM RAM | Memory for Synology

Excellent customer service. Very responsive and helpful.

I have received the 2 memory and everything works perfectly! The customer service is perfect! The shipping is very fast! Thank you for your cooperation!

Arch memory we a pleasure to deal with and the memory works exactly as expected. Would recommend to anyone looking for additional memory for Synology without having to sell a kidney.

I picked up 32GB of this memory for my Synology DS1621+ and I couldn't be happier! The memory is 100% compatible with my NAS and I do not receive any notifications from DSM complaining that I'm using a non-Synology brand! A++ 5 stars! Thanks Arch Memory!

Used two sticks in a brand new DS1621+ and it worked without a hitch. Massive performance improvement for apps and 100% recognized and compatible in the Synology. Saved a ton over the Synology-brand memory as well.

It has been a few weeks since this upgrade. It was working so well I purchased a total of 4 modules for my 2 DS2419+ NASs. They both are running perfectly with 32 GB of memory. If I could give this memory 10 Stars I would. I did contact Arch Memory and talked to Trish. She was incredibly helpful making sure that the parts were correct for my NAS. She was also very reassuring that these parts would work and that they were backed by a 30 day money back warranty and a Lifetime Replacement Warranty. I just don't know how you could go wrong. If you need more memory for your NAS this is the way to go.

Works flawlessly in my DS1621+, no complaints.

I purchased this memory for my Synology RS820+ NAS and it has worked great. I've seen postings in forums about non-Synology memory in these NAS units causing messages to appear about non-Synology memory being unsupported. This memory from Arch Memory has worked fine and I have not seen these messages. The memory was instantly recognized by my NAS unit and has worked without any issues. It just works. Shipping was quick and the memory arrived well packaged. Also, my pre-sale questions were quickly answered with detailed explanations. I am very happy with my purchase, happy to have done business with Arch Memory and will gladly look here in the future as needs arise.

The memory arrived very quickly. When the Synology initialized I was apprehensive due to the number of misc. forum posts about the Synology units reporting about non-Synology memory being installed. That was not the case, the unit powered up and reported the new memory. Both the Synology and I have been very satisfied. I definitely recommend Arch memory for your Synology.
