## Overview

The Western Digital 4TB WD Purple HDD is a surveillance-optimized internal hard drive featuring SATA 6 Gb/s speed, 256 MB cache, and robust 24/7 reliability. Designed to handle high stream-count workloads and support up to 16-bay systems, it ensures smooth, durable performance for professional-grade video surveillance.

## Description

WD Purple drives are designed to meet the challenges of 24x7 video surveillance recording. These 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 drives, you get reliable, surveillance-class storage that’s tested for compatibility in a wide range of security systems. Exclusive WD AllFrame technology helps reduce frame loss and improve overall video playback.

Review: Reliable!!! - This is a very reliable drive; I have three and they work great in both my camera system and my computer. Since it is basically plug and play there is no issues with installation. These are not the cheapest drives but then again you get what you pay for, and these are definitely worth the little extra cost. They seem to last forever, got one that is 6 years old and is still working without a hiccup. Since these are a 4 TB drive, they actually hold about 3.86 TB of data and are pretty quiet compared to other drives I've had in the past.
Review: Good hard drive - Good hard drive for surveillance (continuous) use. My last one lasted ~4 years and ran great the whole time.

## 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.

### ⭐ CARFEFUL...NO WARRANTY AVAILABE
*by F***N on January 5, 2026*

The hard drive failed after 6 months of use in my Security NVR. I went to Western digital for warranty and it was denied. The item was not for sale in the USA and so no warranty. Serial number look up shows it was for sale in Asia so warranty denied.
