It's possible to extract, replace, and upgrade the RAM inside the Synology DS218+, which was one of Synology's best NAS for home. The process only requires a few steps, made easy by the intuitive design of the network-attached storage (NAS) device. You can go from just 2GB of system memory all the way up to a colossal 10GB.

How to upgrade your DS218+ RAM

  1. Take out the two hard drive bays.
  2. The free RAM module slot is located on the side where the power button is.

  1. Enable "Memory test."
  2. Right-click the DS218+ on the list to start the memory test.

You will now be able to take full advantage of 10GB of RAM on the Synology DiskStation DS218+. The official word from Synology is only a 4GB module can be installed (for a total of 6GB), but 10GB seems to work just fine. The Crucial module we've selected is backed by more than 8,000 positive reviews on Amazon. This RAM module is rated to run a little slower than the 2GB module already installed, but that's fine since we're saving money here.

The 2GB stick runs at 1866MHz, while our Crucial upgrade is rated for 1600MHz. If you want to go all out and hit 16GB of RAM, it's possible to replace the original 2GB module, but you need to take apart the NAS entirely, and isn't recommended unless you genuinely need the extra memory. This is where the screwdriver kit comes in handy since you'll need to unscrew a bunch of parts.
