The Western Digital 4TB WD Purple HDD is a surveillance-optimized internal hard drive featuring SATA 6 Gb/s speed, 256 MB cache, and AllFrame technology to reduce video frame loss. Designed for 24/7 operation in demanding environments, it supports up to 180 TB/year workload and up to 16-bay systems, making it ideal for professional and personal security applications.

## 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, and some of our latest models (WD22PURZ, WD42PURZ, and WD63PURZ) have improved power efficiency. Exclusive AllFrame technology helps reduce frame loss and improve overall video playback.

## Features

- Engineered specifically for mainstream surveillance systems.Specific uses: Business, personal
- AllFrame technology delivers optimizations for write-intensive, low bit-rate, high stream-count workloads typical to mainstream surveillance applications.
- Supports up to 180 TB/yr workload rate². | ²Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is annualized (TB transferred ✕ (8760 / recorded power-on hours)). Workload Rate will vary depending on your hardware and software components and configurations.
- 1TB¹ through 3TB support up to eight bays; 4TB and above support up to 16 bays and employ tarnish-resistant components for harsher environments.
- ¹As used for storage capacity, 1TB = one trillion bytes. Actual user capacity may be less, depending on operating environment.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 👍
*by D***H on 26 March 2025*

Everything ok

### ⭐ HDD is not working and dont know how I can get it replaced
*by V***F on 26 March 2023*

The HDD was fitted to our DVR and the technician said it shows only 500 GB when it says clearly its 2 TB. I don't know how to get this fixed. There is no help at all. I am in Coimbatore and would be good to know where I go to hand this over and get a replacement. I think walking to a computer store nearby would have been better. Amazon needs to really look into these deals. I am surely not buying a HDD online in the future. The packing also was a bit suspect but I thought it was like that as it must have come from a wholesaler. I will take it to the service center once I locate one.

### ⭐⭐⭐⭐⭐ Very Good product
*by J***L on 12 March 2024*

Very good performance. No issues.
