Product information

Description

Western Digital Purple WD40PURX is a 3.5" internal hard drive with 4 TB capacity, 5400 RPM rotational speed, 64 MB cache and SATA III interface. Engineered for continuous, always-on surveillance recording, it is intended for use in DVRs, NVRs and multi-drive security systems where reliable long-duration operation, power efficiency and sustained sequential write performance are required. The drive supports a workload rate up to 180 TB/year and is optimized to handle streams from multiple high-definition cameras.

Advantages

The WD Purple drive is built to operate in 24/7 high-temperature environments with firmware tuned for sustained video recording. AllFrame 4K™ technology improves ATA streaming to reduce frame loss and improve playback reliability. With a lower rotational speed and optimized power profile, the drive balances energy efficiency with consistent write performance for continuous surveillance storage. It is validated to support multi-drive systems and a high camera count, enabling scalable storage expansion.

Suitable for

  • Network Video Recorders (NVRs) and Digital Video Recorders (DVRs) for continuous surveillance
  • Multi-bay surveillance systems and storage arrays used in security installations
  • High-definition camera setups requiring long-term, sequential video recording
  • Environments where power efficiency and consistent write performance are important

Key specifications

  • Form factor: 3.5 inch
  • Capacity: 4 TB
  • Rotational speed: 5400 RPM
  • Cache buffer: 64 MB
  • Interface: Serial ATA III (SATA 6 Gb/s)
  • Workload rating: up to 180 TB per year
  • Optimized for continuous 24/7 operation and multi-camera surveillance

How to use

Install the WD Purple WD40PURX in a compatible 3.5" drive bay of your DVR, NVR or storage enclosure and connect via the SATA III interface and appropriate power connector. Configure the recording device following the manufacturer's instructions, initialize and format the drive if required by your system, and verify camera streams and recording schedules. For multi-drive arrays, follow recommended RAID or JBOD configurations specified by your surveillance system to ensure optimal redundancy and performance.

Usage recommendations

Use this drive in systems designed for continuous surveillance; WD recommends 4 TB or greater capacity for many DVR/NVR solutions. For best results, keep firmware and recorder software up to date, maintain adequate cooling in multi-drive enclosures, and consider regular backups or cloning using available tools to protect critical footage.
