Does TerraMaster support flexible RAID like SHR?
Yes. TerraMaster's TRAID is its flexible-RAID option, comparable to Synology's SHR: it lets you combine different-sized drives more efficiently than classic RAID and makes expansion easier, with single- or double-drive fault tolerance. You can also use standard RAID levels. Use CMR drives and check your model's TRAID support in TerraMaster's documentation.

Yes: unlike QNAP, TerraMaster has a direct SHR-style option called TRAID (TerraMaster RAID), built to solve the same mixed-drive-size problem.
What TRAID does
- Mixed drive sizes: like SHR, TRAID reclaims capacity that classic RAID would strand when your drives are not all the same size.
- Easier expansion: add or upgrade drives and TRAID grows the usable space when the maths allows.
- Fault tolerance: TRAID provides single-drive redundancy, with a two-drive-tolerant variant on supported models, the analogue of SHR vs SHR-2.
TRAID or standard RAID?
Use TRAID if you want to mix drive sizes or keep expansion simple: the typical home/small-office choice. Use standard RAID (5/6/10) if all your drives match or you value cross-platform array portability. Confirm TRAID support and the exact redundancy options for your model in TerraMaster's documentation.
Drive choice is unchanged
Whichever you pick, populate it with CMR NAS or enterprise drives and avoid SMR in RAID. The table lists in-stock CMR drives by price per terabyte.
