# Seagate BarraCuda 8TB Buying Guide: ST8000DM004 Price, SMR and Best Use

Canonical: https://cloudzat.com/seagate-barracuda-8tb/

Purpose: shopper-first buying guide.

Decision: Buy ST8000DM004 for low-cost bulk desktop storage when reads dominate and long write slowdowns are acceptable. Choose WD Blue WD80EAAZ for a current desktop CMR option, IronWolf for NAS duty, or BarraCuda 12TB when a larger current CMR model provides better value per terabyte.

- Good fit for: Large read-heavy storage — Media libraries, archive storage and backups with moderate rewrite frequency are the strongest cases.
- Avoid for: Parity-heavy or rewrite-heavy arrays — Large SMR drives can be awkward for repeated rebuilds, sustained rewrites and near-full write workloads.
- Worth comparing: 8TB CMR alternatives — At this capacity, check the live price gap to IronWolf or another documented CMR drive before deciding.
