## Overview

The Western Digital 8TB WD Purple Surveillance HDD is a purpose-built internal hard drive designed for professional and personal surveillance systems. Featuring a robust 8TB capacity, SATA 6 Gb/s interface, and 128MB cache, it supports high stream-count, write-intensive workloads typical of 24/7 security environments. Enhanced with AllFrame AI technology, it reduces frame loss and optimizes video playback, making it ideal for AI-enabled NVRs and multi-bay setups. Engineered to withstand heat fluctuations and vibrations, this drive delivers reliable, long-term performance for uninterrupted surveillance.

## 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.

Review: Super Easy to Install & Works Like A Charm! - I needed to replace the 2 TB hard drive in my NightOwl 3 MP Surveillance Camera system, because the original hard drive quit recording after three years of service. I was on the fence about whether to invest my money into replacing the failed hard drive with this new Western Digital 4TB Purple hard drive, or spend a little bit more money, and replace the entire system. Since I’m not a Computer Tech by any means, the thought of ignoring the manufacturer’s warning labels against opening up the DVR case, and then then having to poke around with a screw driver, to uninstall the old, to replace with it with this new one made me nervous. I understand hard drives to be fragile, and the thought of handling these hard drives during the swap, was scary to me. I couldn’t afford to mess it up. Much to my surprise, it was an extremely simple task. I did watch a utube video on it beforehand, which did help me. It took more time to unscrew the DVR case, than than it did to swap out the parts. It’s just a matter of unplugging the old one, and plugging in this new one. Close the case back up, power on, and follow the on prompts in the screen. This 4Tb Western Digital Purple hard drive made especially for surveillance applications, installs itself from there. It was quick. It was easy, and it has performed. The best part is that it saved me money from having to purchase a whole new system. I’m very happy with my purchase. I believe it was money “well spent”, and I can highly recommend this Purple hard drive, with confidence. Thank you, Western Digital, for producing a quality product

## Questions & Answers

**Q: can it replace older hhd in nightowl dvr**
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: Absolutely nothing. They are the same.

**Q: Is this compatible with annke surveillance camera system 8ch 1080p lite h.264+ dvr with (8) hd 1080p outdoor weatherproof cameras cctv security camera**
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.
