About this product
The WD WD40PURX Purple 4TB Surveillance Hard Drive is a 3.5-inch internal desktop drive with a 4TB storage capacity. This drive, model WD40PURZ, is part of the Purple product line, indicating its optimization for surveillance applications. It features a 5400RPM rotation speed, a 64MB cache, and a SATA III interface, making it suitable for continuous operation in security camera systems requiring reliable data recording.
Our take
If you're setting up a surveillance system, this WD Purple 4TB drive is purpose-built for it. The 5400RPM speed, while slower than some desktop drives, is actually optimized for the constant read/write cycles of surveillance footage, prioritizing reliability and longevity. With a 64MB cache and SATA III interface, it's adequately equipped for streaming multiple video feeds. At 4TB, it offers plenty of space for weeks of recordings. It’s a workhorse for DVR/NVRs, designed to run 24/7 without a hitch, but don't expect it to be a speed demon for a gaming PC.
