Seagate SkyHawk HDD Spec and Price in the United States
SkyHawk is Seagate's surveillance line: a low-RPM spindle tuned for the sustained sequential writes of video recording, a 256MB cache, and a 180TB/year workload rating, per the Seagate data sheet. ImagePerfect is Seagate's marketing for the frame-drop-free streaming claim, and the firmware is built for always-on DVR duty. The three-year warranty matches WD Purple; the choice between them is usually price and NAS-or-surveillance branding.
