About this product
The WD WD40PURX Purple 4TB 3.5" SATA 3 Hard Drive is an internal desktop drive designed for surveillance applications. It features a 4TB storage capacity, a 5400RPM rotation speed, and a 64MB cache. This 3.5-inch form factor drive connects via a SATA III interface, making it suitable for systems that require consistent data writing over long periods, typical of security camera setups. Its Purple product line designation indicates optimization for 24/7 surveillance workloads.
Our take
If you're building a surveillance system, this WD Purple 4TB drive is specifically tailored for that purpose. The 5400RPM speed, combined with a 64MB cache, is adequate for continuous video recording, which is what these drives are optimized for. Don't expect blazing fast speeds for general desktop use or gaming, as that's not its primary design. However, for reliable, always-on operation in a DVR or NVR, it should perform well. The 4TB capacity offers plenty of space for many hours of footage.
