Seagate SkyHawk 4TB Surveillance Hard Drive 3.5" SATA 5900RPM

Seagate SkyHawk 4TB: what it's actually for

A DVR or NVR writes continuously, 24 hours a day, from multiple camera streams — a desktop drive isn't built for that pattern. The Seagate SkyHawk 4TB is Seagate's surveillance-specific answer to it.

Key specs

• Capacity: 4TB, enough to hold footage from several cameras before older recordings cycle out
• Interface: Uses a 3.5-inch SATA III interface running at 6 Gb/s.
• Firmware: SkyHawk ImagePerfect, tuned to keep sequential video writes stable across simultaneous camera streams
• Built to run non-stop, 24 hours a day, 7 days a week.
• Workload: supports multi-camera surveillance recording

Where it fits a job

Retail premises, warehouses, offices and residential blocks running DVR or NVR recorders all generate the same always-on write load. This drive is specified for exactly that, rather than for general desktop use.

Selection notes for installers

Before ordering, confirm the recorder has a free 3.5-inch SATA bay and supports SATA III. On multi-camera jobs, checking recorder channel count and resolution against expected retention helps decide whether 4TB is enough or whether a larger SkyHawk capacity is the better spec.

The ImagePerfect firmware is the practical reason to choose a surveillance-rated drive over a standard one: it's engineered to reduce dropped frames when several HD streams are writing to disk at once, which matters most on busy multi-camera systems.
