## Overview

The Western Digital 8TB WD Purple Surveillance HDD is a 3.5-inch internal hard drive designed specifically for continuous, write-intensive surveillance workloads.

## Description

The right drive for the right job. WD Purple drives are engineered specifically for surveillance to help withstand the elevated heat fluctuations and equipment vibrations within NVR environments. An average desktop drive is built to run for only short intervals, not the harsh 24/7 always-on environment of a high-definition surveillance system. With WD Purple, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback. WD Purple 8TB* and higher drives have additional performance headroom to support a new generation of AI-enabled NVRs, video analytics appliances, and deep-learning servers. * As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.

A: Yes. This hard drive is compatible with all recording units.

**Q: What is the difference between 3tb purple wd30purz and wd30purz, very confusing?**

A: As the owner of South Jersey Surveillance Systems, I can assure you that any WD purple or Seagate Skyhawk hard drive is the appropriate type of storage drive for any and all DVRs and NVRs.

**Q: Whats the difference between this and the red plus?**
A: WD Blue HDDs are mainly used for general purpose storage, they are great all-rounders, and an average user can’t go wrong with Blue.

WD Green is basically same as Blue, but it lacks a bit of performance. However, it is the most eco-friendly HDD, and it’s quite cheap.

WD Blacks are for pure performance including gaming, media, and content creation. Also one of the most expensive HDDs.

WD Red is a NAS drive. It’s optimized for NAS systems.

WD Purple is for surveillance. Advised for 24/7 operation.

WD Gold, probably the most premium of all. Made for a multitude of Datacenter-specific applications.
