Is Seagate IronWolf right for your NAS?
For a home or small-office NAS, yes. IronWolf drives are CMR, tuned for 1 to 8-bay units running 24/7, with rotational vibration sensors on the higher capacities and IronWolf Health Management. Standard IronWolf spans 1TB to 12TB with a 3-year warranty; IronWolf Pro runs at 7,200 RPM up to 24TB with a 5-year warranty.
Being CMR, IronWolf rebuilds RAID arrays cleanly, unlike the SMR desktop drives you should keep out of a NAS.
IronWolf vs IronWolf Pro
| IronWolf | IronWolf Pro | |
|---|---|---|
| Capacities | 1TB to 12TB | 2TB to 24TB |
| Speed | 5,400 to 7,200 RPM | 7,200 RPM |
| Warranty | 3 years | 5 years + Rescue |
| Workload/yr | 180 TB | 300 TB |
| Best for | 1 to 4-bay home NAS | Larger or busy arrays |
Which to choose
- 2 to 4-bay home NAS: standard IronWolf is plenty and the better value.
- 5+ bays or heavy use: IronWolf Pro for the higher workload rating and 5-year warranty.
- Maximum capacity or lowest $/TB: consider Seagate Exos, which trades quiet operation for value.
Pros, cons and the bottom line
Bottom line: IronWolf is a default home-NAS drive. Buy standard for small arrays, Pro for bigger ones, and Exos if you want the most terabytes per dollar.
- Pros: CMR and RAID-safe, health monitoring, quieter than enterprise drives, wide capacity range.
- Cons: standard model tops out at 12TB; Pro costs more than desktop drives.
