Synology DDR3 1866 MHz SO-DIMM Reviews

Preferred by Synology...

But at a higher price than comparable modules are available for. Is it worth it? I don’t know. Synology will not warrant your device if you use another brand so.... seeings how this was a new NAS, and the warranty is important to me, I paid the premium. The module works fine, and installation was very easy. If I were expanding the memory in a unit that was off warranty, I’d definitely give a cheaper chipset a try. I give this module five stars because it did work flawlessly and I won’t ding it for being a bit pricey —- OEM stuff always is.

It must be working, because the Synology 218+ is running like slick lightning. Also using WD Red Pro HDD @ 7200 rpm. It was a snap to install -- Pun intended -- before loading the hard drives. The total hardware setup only took a few minutes. Love my network'd file sharing setup.

This looked like an inexpensive upgrade to provide additional buffering for the Synology NAS. Easy installation and zero problems.

Didn't want to over the recommended 6 GB of RAM on my NAS so just upgraded the 4 GB but works great. Honestly for what I'm using mine for its more then enough.

question

What's the advantage of buying this Synology 4GB DDR3L 1866 MHz SO-DIMM Memory Module? Is it a noticeable difference in speed and power on the Synology NAS box?
Asked by: Nigel B.
Some folks say it is used to cache some user data for SMB, file services, network shares. I personally could not directly dig up any info on that from Synology. So, if you ask me, I don't think so, not for basic SMB. The main benefit of additional RAM is if you were to run VMs on the NAS or install additional Apps i.e. Run DHCP, DNS services, anvivirus etc.
