Seagate IronWolf 8TB (NAS, CMR)
An enthusiast-tier 8TB NAS drive using CMR at 7200 RPM with 256MB cache, rated for 24/7 duty in multi-bay enclosures, which is the key distinction from the SMR BarraCuda line. It's the right pick for proper NAS bays that need reliability and consistent writes. Skip it for desktop game libraries, where the cheaper BarraCuda suffices, and for quiet builds, since 7200 RPM NAS drives are audibly active.
