This exact model is now sold through Western Digital’s outlet channel and has been superseded in the current 24TB lineup, so compatibility and sourcing should be confirmed before it is offered to a customer. The product record is complete for inventory planning, but it remains unpublished until its lifecycle and supply position are approved.

A 550TB-per-year workload rating, 7200 RPM-class performance, 512MB cache, and up to 272 MB/s transfer rate make it ready for sustained surveillance use. It also carries a 2.5 million-hour MTBF rating and five-year warranty. This is the right scale for warehouses, multi-building properties, and other systems where losing days of video to limited capacity is not acceptable.

This is a commercial-grade step above the standard Purple line, with a 7200 RPM-class design, 512MB cache, up to 267 MB/s transfer rate, two million-hour MTBF, and five-year warranty. For a compatible recorder using analytics or higher camera counts, 10TB provides serious retention without jumping straight to the largest enterprise capacities.

With up to 215 MB/s transfer performance, a 256MB cache, CMR recording, and support for up to 16 drive bays, the 8TB model is suited to longer retention goals at active businesses and multi-camera properties. It is the sensible high-capacity choice when standard surveillance workloads are the priority and advanced AI-stream ratings are not required.

The drive is built for continuous surveillance workloads with CMR recording, AllFrame technology, support for up to 64 HD cameras, and compatibility with systems using up to 16 bays. A 180TB-per-year workload rating helps it handle a steady stream of video. This is a meaningful capacity upgrade for properties that care more about retention than simply meeting the minimum storage requirement.

Support for up to 16 drive bays leaves room for systems that may grow over time, and the 180TB-per-year workload rating is built around the demands of continuous video. For a property owner choosing storage for a new video recorder, 4TB is often the practical sweet spot between entry-level capacity and a larger commercial drive.

This model supports up to 64 HD cameras and expands to compatible systems with as many as 16 drive bays, making it flexible enough for a well-equipped home or growing small business. A 180TB-per-year workload rating and one million-hour MTBF round out the design. It is the balanced pick when both retention and overall system cost matter.

Compared with a 1TB starter drive, 2TB gives footage more time before the recorder begins overwriting older events. It uses CMR recording, includes a larger 256MB cache, and supports systems with up to eight bays. It is a well-matched upgrade for a compact system that needs more history without a large jump in hardware cost.

Its 1TB capacity fits compact residential and light-commercial systems where the camera count or retention goal is modest. The drive uses CMR recording, supports systems with up to eight bays, and is rated for 180TB of workload per year. This is a straightforward, cost-conscious choice when you want the right kind of drive for surveillance rather than repurposing ordinary computer storage.

The 2TB capacity is a useful step up for a home, office, or small storefront that wants more history available before older footage is overwritten. It works in systems with up to eight bays and carries a 180TB-per-year workload rating, one million-hour MTBF, and three-year warranty. For customers balancing retention and cost, this is the stronger small-system value in the SkyHawk pair.
