Size Your TrueNAS Memory to Your Pool

Recommended memory for your ZFS pool size and workload, and why ECC is worth it

Quick answer

TrueNAS runs on 8GB but 16GB is the sensible baseline, then roughly 1GB of RAM per TB of pool as a rule of thumb for the ARC read cache. Media pools need less because they are sequential; VMs and apps need more for their guests; deduplication needs about 5GB per TB and should only be enabled if your data actually dedupes. ECC memory is strongly recommended for ZFS.

Usable price per TB

—

With 4x 8TB in Synology SHR you get about 21.83 TB usable and 1-drive fault tolerance.

Usable capacity is shown after binary and filesystem overhead (about 9%). Fault tolerance is not a backup; keep a separate copy of important data.

What the RAM is actually for

Most TrueNAS RAM becomes ARC, the ZFS read cache that keeps hot data in memory. More ARC means more cache hits and a snappier pool, which is why the 1GB-per-TB rule exists, but it is a guideline, not a hard floor: an 80TB media server runs happily on 32GB because its reads are large and sequential.

Deduplication is the big exception. Its table lives in RAM at roughly 5GB per TB, and if you run out the pool can grind or fail to import. Leave dedup off unless you have measured a real dedup ratio on your data.

Memory type

ECC preferred

General file serving: the classic rule is about 1GB of RAM per TB of pool over an 8GB base. More ARC means more of your data is cached in RAM.

ECC RAM is strongly recommended for ZFS so silent bit-flips are caught before they reach your data. TrueNAS runs on non-ECC, but for a pool you care about, ECC is the safer build.

Frequently asked questions

Is 16GB enough for TrueNAS?

For a general home NAS up to about 16TB, yes. Past that, add roughly 1GB per TB for a responsive ARC cache. If you run VMs or apps on SCALE, budget their RAM on top of that baseline.

Does TrueNAS need ECC RAM?

It works without ECC, but ECC catches silent bit-flips before they reach your data, which matters for a filesystem built around integrity. For a pool you care about, ECC is the safer choice; see the ECC RAM for NAS page.

How much RAM for Plex on TrueNAS?

Plex itself is light; the storage side is sequential so ARC helps less. 16 to 32GB covers a large media pool. Transcoding is CPU or GPU work, not RAM, so do not over-buy memory for Plex.

Do I need RAM for deduplication?

Only if you enable it, and then a lot: about 5GB per TB for the dedup table. Most home users should leave dedup off and rely on compression, which is nearly free and on by default.
