Seagate IronWolf Pro HDD Spec and Price in the United States
IronWolf Pro is Seagate's heavy-duty NAS drive: 7200rpm across every capacity, 256MB of cache, a 300TB/year workload rating, and a five-year warranty, per the Seagate data sheet. The Pro designation buys the doubled workload rating and the longer warranty compared with the base IronWolf, plus the higher sustained throughput at the top capacities. It is the pick for large multi-bay arrays and RAID rebuilds, priced accordingly against WD Red Pro.

- Its workload rating and mean-time-between-failures figures suit multi-bay arrays.

Commonly criticised
- It is expensive, with street pricing above the launch list.
