About this product
The WD Purple 3TB Internal Hard Drive is a 3.5-inch HDD specifically designed for surveillance systems. It features a 5400 RPM rotation speed, a large 256MB cache, and a SATA III interface.

It comes with a 3-year manufacturer warranty, emphasizing its reliability for security applications.
Our take
For dedicated surveillance systems, the WD Purple 3TB drive is an excellent choice. It's specifically engineered for 24/7 operation, which is critical for security camera footage, and the 3-year warranty adds significant peace of mind. The 256MB cache is generous for a 5400 RPM drive, helping with write performance. While the 5400 RPM speed might seem slow, it's often preferred for surveillance drives to reduce heat and power consumption, as sustained writes are more important than peak speed. It's a reliable workhorse for NVRs.
