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

update: dec’21:

LA MEMORIA RAM DE 4GB, SE NOTA AL INCORPORLA EN LA NAS, FUE FACIL DE INSTALAR Y LOS ARCHIVOS PESADOS NO SE NOTAN AL PASAR DE UNA CARPETA A OTRA O AL VER UN VIDEO O PRESENTACION.

The RAM chips that are actually soldered to the board are Samsung. Go with an 8GB stick of Samsung for compatibility and a lower cost. Get the M471A1K43CB1-CTD. Works great on my DS220+ and my DS720+. It tests out with Synology Assistant memory test, plus, theres no errors/nuisance warnings that youre not using a Synology branded stick of memory.

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

Its a good product so Id recommend this to anyone needing extra memory for a NAS drive, which all NAS drives need the extra memory. It is expensive though, so this is part of the price of NAS drive we often fail to take into account.

Worked perfectly from the outset. I really dont stress my NAS but I wanted to ensure the best performance from the start. Got the Synology extended warranty so wanted to get a factory approved part.

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.

As stated, nothing more to add.

Yep. Its fast.

$90 for a 4GB DDR4 ram chip!
