Which should you buy?
Coverage-wise, Seagate IronWolf appears on more Synology machines (169 vs 151) — for an older or unusual model that margin can matter. The lines differ in intent though: NAS vs Enterprise NAS — Seagate IronWolf is tuned for sustained NAS writes and RAID rebuilds, and the same logic applies on the other side.}
Both lines overlap on 147 Synology models — if yours is one of them, either drive is officially supported.
