22TB WD Purple Pro Surveillance Hard Drive for DVR and NVR

22TB WD Purple Pro Surveillance Hard Drive for DVR and NVR Recording

The 22TB WD Purple Pro Surveillance Hard Drive, model WD221PURP, is a high-capacity 3.5" SATA hard drive built for professional video surveillance recording. It is a good choice for compatible security DVRs, NVR recorders, and larger security camera systems that need longer local video retention.

This drive is intended for always-on surveillance storage, where video footage is constantly being written to the disk. For customers using multiple cameras, high-resolution video, motion recording, or 24/7 continuous recording, a 22TB surveillance hard drive can help extend how long footage is stored before older recordings are overwritten.

High-Capacity Storage for Professional Camera Systems

A 22TB hard drive is especially useful for larger systems, 4K recording, business surveillance, and installations where local storage is preferred over monthly cloud storage. It pairs well with many compatible 4K security camera systems, PoE NVR recorders, and commercial recording setups.
