NAS Memory by Brand: Synology, QNAP, ASUSTOR, TerraMaster, UGREEN
Network-attached storage memory for the NAS systems that hold business files, backups, virtual machines and media, matched model by model to each maker's memory specification: generation, module type, speed and slot count. NEMIX RAM lists five NAS brands below, from current DDR5 desktop and all-flash systems to older DDR3L units that are still in service. If you manage one NAS or a dozen, this page is the map.

| UGREEN | NASync DXP series | 13 listings | hub page · guide |
Listings are model-level: each one is a single NAS model with the module type, speed and capacities it takes. The NAS memory collection brings the brands together, and each brand also has a part-number cross-reference collection: Synology, QNAP, ASUSTOR and TerraMaster.
What memory does a NAS use?
| NAS class | Module type | Where to look |
|---|---|---|
| Home, small office and most desktop NAS | SODIMM, mostly non-ECC | Every brand above |
| Business desktop and entry rackmount | ECC SODIMM or UDIMM | Synology Plus models, QNAP TS-h and TVS-h, ASUSTOR Pro, TerraMaster U-series |
| Enterprise rackmount, all-flash and HA clusters | ECC RDIMM | Synology SA, FS and HD, QNAP ES and TS-h FU series |
The catalog covers DDR3L, DDR4 and DDR5. SODIMM, UDIMM and RDIMM are not interchangeable, and each generation has its own slot key. ECC memory is the safer choice for business data and virtual machines where the NAS supports it. The NAS memory guide walks through identifying your model, choosing the module type, ECC and capacity.
Looking for a different kind of memory?
Compact NAS and mini PCs often share modules with laptops, so the DDR4 non-ECC SODIMM collection is a useful cross-reference. Rack servers are on the data center and server memory page, and desktops and laptops for offices and schools are on the business fleet memory page.
