Seagate Skyhawk 4TB 5400 RPM Surveillance Internal Hard Drive

The Seagate SkyHawk 4TB Internal Hard Drive (model ST4000VX016) is purpose-built for always-on security and surveillance environments. Operating 24 hours a day, 7 days a week, it carries Seagate's ImagePerfect firmware, which is engineered to reduce dropped frames and skipped footage during continuous multi-stream recording workloads — supporting ATA streaming from up to 64 high-definition cameras simultaneously. The drive fits into enclosures supporting up to 16 drive bays and uses CMR (Conventional Magnetic Recording) technology on a standard 3.5-inch form factor. SkyHawk Health Management is included with this drive and provides proactive monitoring focused on prevention, intervention, and recovery options to help keep your surveillance storage healthy over its lifespan. For environments running RAID arrays, the included RAID RapidRebuild technology delivers up to 3× faster volume rebuilds compared with traditional RAID rebuild processes, minimising downtime after a drive replacement event. Rotational Vibration (RV) sensors are built in to help maintain consistent performance in multi-bay systems. Tarnish-resistant components add a layer of environmental protection, improving field reliability in dusty or variable-humidity surveillance installations. Power consumption is kept low — average operating power is rated at 3.7 W, with idle averaging 2.5 W and standby/sleep at just 0.25 W — helping reduce heat output and long-term operating costs. Every ST4000VX016 ships with a 3-year Rescue Data Recovery Services plan from Seagate, giving operators access to Seagate's in-house data recovery services in the event of drive failure.
