# Seagate BarraCuda Buying Guide: Best Models, CMR/SMR, Prices and Uses Canonical: https://cloudzat.com/seagate-barracuda/ Purpose: shopper-first buying guide. Decision: Use the exact model number as the buying key. Current 1TB through 8TB BarraCuda models are SMR, while the current 12TB, 16TB, 20TB and 24TB models are CMR. BarraCuda is primarily a desktop and direct-attached-storage family. For RAID, multi-bay NAS use or heavier always-on workloads, compare IronWolf before buying. - Best fit: Desktop bulk storage — Good for secondary storage, media, game libraries and ordinary local backups when the exact model matches the workload. - Choose something else if: You need NAS or heavy rewrites — For multi-bay NAS, RAID or sustained write-heavy use, compare IronWolf or another CMR-focused alternative. - Key buying rule: Buy by exact model — Two drives with the same BarraCuda name can use different RPM, recording methods and workload ratings.
