Seagate IronWolf HDD Spec and Price in the United States

SATA4TB5400 RPM

IronWolf is Seagate's NAS line: 5400rpm at the small capacities and 7200rpm from 8TB up, 256MB of cache, a 180TB/year workload rating, and a three-year warranty, per the Seagate data sheet. AgiLeDrive is Seagate's name for the firmware that tunes the drive for RAID-friendly sustained writes; the practical facts are CMR recording and a design target of 24/7 multi-drive operation. It is the direct competitor to WD Red Plus, typically a little cheaper per terabyte.
