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

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

It does what it is supposed to do. Just a bit expensive due to its Synology branding and certification. Other brands of this spec likely would have worked just as well for a lower cost.

Synology says if you use any memory but theirs your Synology will blow up and no warranty.

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.

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

Four stars because of price, but other than that I have had no issues when using with DS220+. Rock solid

Easy.

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.

It is designed for the synology, I went with brand recommended

Synology nas use.
