The Seagate SkyHawk AI is a 20 TB hard disk drive engineered for video surveillance systems that utilize artificial intelligence. It is constructed to operate on a 24/7 basis, supporting multiple high-definition camera streams and complex analytics workloads simultaneously. With a standard 3.5-inch form factor and a SATA 6.0 Gbit/s interface, this HDD integrates directly into compatible security installations. The drive is specifically tuned for the demands of steady, uninterrupted data recording and processing required by modern surveillance applications.
Performance is supported by a 256 MB cache, which facilitates consistent data throughput from high-resolution sources. Integrated rotational vibration (RV) sensors help maintain performance and reliability in multi-drive enclosures by mitigating the effects of operational vibration. The drive is rated for a Mean Time Between Failures (MTBF) of 2,000,000 hours, reflecting its design for long-term deployment in critical surveillance environments. Its sustained read and write speeds are specified at 260 MB/s, accommodating the data rates of modern cameras.
