The Seagate SkyHawk AI is a 20TB surveillance hard drive built for network video recorders and AI-enabled cameras. It uses conventional magnetic recording at 7200 RPM with a 256MB cache and a SATA 6Gb/s interface, and Seagate rates it for up to 64 HD camera streams and around 550TB of writes per year. It suits installers and businesses running large multi-camera systems who need capacity and sustained write endurance. Against WD Purple drives it offers more cache and a higher workload rating, but it is louder and hotter than 5400-class surveillance drives and costs more than desktop drives of the same capacity.

Owners of Seagate's large SkyHawk drives generally report reliable long-term recording in NVRs and praise the capacity and write endurance. Complaints center on noise, heat and the occasional early failure, which is common to high-capacity helium drives across brands.
