# Seagate BarraCuda CMR vs SMR Buying Guide: Model List, Uses and Prices

Canonical: https://cloudzat.com/seagate-barracuda-cmr-smr-model-list/

Purpose: shopper-first buying guide.

Decision: Current 1TB through 8TB BarraCuda models are SMR. Current 12TB through 24TB models are CMR. Both current 2TB variants are SMR, including the 7,200 RPM ST2000DM008. Use the model number rather than a retailer's generic family title.

- SMR makes sense for: Mostly-read desktop storage — Media libraries, game archives and backup targets with moderate rewrites can be good fits when price is the priority.
- CMR makes sense for: Sustained rewrites — Choose CMR when repeated large writes, rebuild behavior or predictable write performance matters.
- Do not assume: RPM tells you CMR vs SMR — A 7,200 RPM BarraCuda can still be SMR. Verify the exact model number before buying.
