Best RAM for the TerraMaster F2-425
By Devin Chua · Data checked by Owen Nakamura · Updated The TerraMaster F2-425 ships with 4 GB of DDR4 SO-DIMM, no ECC (1 slot) and officially takes 16 GB. What benefits from the upgrade is specific to this box: the Intel N5095 (4 cores, 2.0 GHz) hardware-transcodes and runs containers, and those — not plain file storage — are what more memory feeds.

What sets the F2-425 apart
The cheapest x86 two-bay with 2.5-gigabit networking. With two equal-size drives TRAID gives no advantage over RAID 1; it only gets interesting once you add a larger drive later.
What more memory buys on the F2-425
The F2-425 takes DDR4 SO-DIMM, no ECC (1 slot) up to an official 16 GB, across 1 slot, starting from 4 GB. Whether that upgrade earns its money is a question about this exact box: the Intel N5095 (4 cores, 2.0 GHz) transcodes Plex and runs containers, and it is the containers, not the file shares, that ask for more RAM.
The F2-425 uses non-ECC DDR4 SO-DIMM, no ECC (1 slot), so a flipped bit is not corrected. That is rarely a problem in practice, but it is why DIY TrueNAS builders insist on ECC; on the F2-425 you simply match the SO-DIMM spec and standard sticks are fine. 16 GB official

Keep calculating
To see how much capacity is left after parity, the F2-425 capacity calculator is preset to its 2 bays and RAID types. For the F2-425, the wider basics of choosing a drive are in the buying guides, where we also explain why CMR rather than SMR is mandatory in any RAID array.
Frequently asked questions
What memory does the F2-425 use?
DDR4 SO-DIMM, no ECC (1 slot), starting from 4 GB. 16 GB official It uses standard non-ECC modules.
Can the F2-425's memory be upgraded?
Yes. The F2-425 has one slot, officially to 16 GB.
Is more RAM worth it in the F2-425?
Only if you run containers. The F2-425's Intel N5095 (4 cores, 2.0 GHz) transcodes and runs Docker well, and it is the containers — not file shares — that ask for more than the stock 4 GB.
Can I put third-party drives in the F2-425?
Yes. TerraMaster locks no drive brand on the F2-425 — its compatibility list is guidance, not a gate — so any CMR NAS drive works.
