About this product
The WD Purple 2TB Surveillance Hard Disk is an internal 3.5-inch drive designed for DVR and surveillance systems. It features a SATA 6 Gb/s interface and operates at a 5400 RPM class rotational speed. With a 64MB cache, this drive is engineered for reliable, always-on surveillance workloads, offering a 2TB storage capacity in a standard desktop form factor. Its specific design caters to the demands of continuous recording environments.
Our take
If you're setting up a surveillance system, this WD Purple drive is a solid choice for dedicated recording. The 2TB capacity offers a good amount of storage for a smaller setup, and the 5400 RPM class, combined with the 64MB cache, is optimized for consistent video streaming rather than raw speed. It's an internal 3.5-inch drive, so ensure your DVR or NVR has the appropriate bay. While it's not the fastest drive on the market, its strength lies in its reliability for constant operation in a surveillance context. The SATA 6 Gb/s interface provides decent data transfer rates for its intended use.
