5 Things to Know About the F4-421's RAM

The F4-421 has 4GB of DDR3 soldered directly to the motherboard. There is no SO-DIMM slot for expansion.

What the device ships with is the maximum RAM it can ever have. You cannot upgrade or replace the memory.

The RAM is non-ECC, which is standard for consumer NAS devices. This limits its use in environments requiring error-correcting memory.

The soldered design reduces upgrade flexibility but improves reliability. There are no loose connections or compatibility issues to worry about.

If you need more than 4GB of RAM, this model is not for you. Look for a NAS with a memory slot or higher base capacity.
