4 Things to Know About the DS420+ RAM Upgrade

  1. The DS420+ has 2GB of DDR4 soldered directly to the motherboard. This memory cannot be removed or replaced.

  2. It includes one SO-DIMM slot that accepts a 4GB module. This brings the total to 6GB maximum.

  3. The 6GB ceiling is tight for a 4-bay NAS. Most 4-bay models in this class support 8GB or more.

  4. The upgrade is easy to install but limited in payoff. You get a modest boost, but the soldered 2GB remains a bottleneck.
