TerraMaster ECC memory support?

[Arjestin]

Hi,

I'm looking for a 12/16 bay rackmount NAS that supports ECC memory. TerraMaster has some models that are very fairly priced, but I could find none that officially support ECC memory. Even the U8-450 model with its Atom C3558R, does not support ECC memory according to the specifications on TerraMaster website. It seems strange to me that a major NAS brand like TerraMaster does not have any models with ECC support.

1. Do any of the TerraMaster 12/16 bay rackmount NAS support ECC memory unofficially?
2. Can you recommend me a non-TerraMaster NAS that is fairly priced for its hardware? I'm going to replace the OS with TrueNAS running under Proxmox, so software doesn't really matter to me.

Thanks,
Arjestin

You're absolutely correct that TerraMaster's NAS lineup, including the U8-450 with the Atom C3558R, does not officially support ECC memory. This is a notable limitation for users who prioritize data integrity and reliability, especially in larger setups like 12/16 bay rackmount systems.

1. TerraMaster and ECC Memory Support
TerraMaster doesn’t officially support ECC memory across its current models, even those with processors that could theoretically support ECC. While it’s possible that some models might work with ECC memory unofficially (due to the CPU's support for ECC, like the Atom C3558R), this is not guaranteed and depends on the motherboard’s implementation. Without official support, even if ECC is physically accepted, the error correction functionality may not work.

If you’re set on TerraMaster, you might:

Contact their support to inquire about unofficial compatibility.
Check community forums or user reports for anecdotal evidence of ECC compatibility.
However, for a mission-critical system, relying on unofficial support is not advisable.

2. Alternatives with ECC Support
If ECC support is essential, here are some alternatives:

Synology
RackStation RS2423+/RS2423RP+:
12-bay with ECC support (AMD Ryzen V1780B CPU).
Synology's models tend to be pricier but offer excellent hardware reliability.
QNAP
TS-h1887XU-RP:
12-bay with ECC support (Intel Xeon D-1622 CPU).
Supports ZFS natively if you don’t want to replace the OS.
Expandable and highly configurable.
Asustor
Lockerstor 12R Pro:
12-bay with ECC support (Intel Xeon E-2224 CPU).
Affordable compared to other brands offering ECC.
Custom Builds or DIY
Consider a custom-built server with:
Supermicro motherboards that support ECC memory.
CPUs like Intel Xeon E-series or AMD EPYC for ECC compatibility.
More flexibility and often better value for your budget, especially if you’re running TrueNAS under Proxmox.
Dell/HP/Lenovo Prebuilt Servers
Entry-level rackmount servers (e.g., Dell PowerEdge R540 or HP ProLiant DL380) can be adapted for NAS use with TrueNAS.
