Best RAM upgrade for the TerraMaster F2-425 Plus

Best RAM picks for the F2-425 Plus

Three sensible ways to add memory, from cheapest single-stick option to a matched 16GB pair.

Which should you pick

What actually changes with more RAM on this NAS

The F2-425 Plus ships with 8GB of DDR5, which is enough for two 5GbE network shares, SMB, and Plex hardware transcode without breaking a sweat, since the Intel N150 handles the video decode work rather than the RAM. Where memory matters is caching, background indexing, and how many applications you can run at once through TerraMaster's app centre.

With three M.2 NVMe slots available for cache or storage pools, a busier setup with NVMe caching and multiple containers will lean on system memory more than a simple two-bay file store. If you plan to add an NVMe cache pool alongside Docker workloads, 16GB is a comfortable, low-risk step up from the stock 8GB.

Going to the full 32GB means removing the factory-fitted 8GB module and fitting two 16GB sticks, since this model has only two SO-DIMM slots. Buying two 8GB modules as listed above gets you to 16GB total, which covers most home and small office use cases without needing to source larger capacity modules.

One honest caveat
