WD Purple Surveillance Hard Drive – 24/7 CCTV & NVR Storage

WD Purple Surveillance Hard Drive (1TB–6TB)

WD Purple Surveillance Hard Drive is engineered specifically for 24×7 CCTV, DVR, and NVR systems. Unlike standard desktop hard drives that are designed for short, intermittent use, WD Purple drives are built to withstand continuous operation, elevated temperatures, and system vibrations commonly found in surveillance environments. Available in 1TB, 2TB, 4TB, and 6TB capacities, WD Purple offers reliable and scalable storage for both small and large security setups.

Designed by Western Digital, a global leader in storage solutions, WD Purple ensures smooth, uninterrupted video recording and dependable playback when it matters most—whether you are securing your home, office, retail store, or industrial premises.

WD Purple Surveillance Hard Drive – Key Features

WD Purple drives are optimized for write-intensive workloads, making them ideal for modern surveillance systems that run non-stop. The drives use CMR recording technology to ensure consistent performance and data integrity during continuous video recording.

Exclusive AllFrame™ technology improves ATA streaming, helping to reduce video frame loss and enhance overall playback quality across supported DVR and NVR systems. This ensures clear, reliable footage even in multi-camera environments.

WD Purple Surveillance Hard Drive for CCTV & NVR Systems

Modern surveillance systems often support multiple video streams per camera. WD Purple Surveillance Hard Drives are designed to support up to 64 single-stream HD cameras, depending on capacity, making them suitable for both basic and advanced CCTV installations.

With a workload rating of up to 180TB per year—up to three times higher than desktop hard drives—WD Purple can easily handle the demands of continuous video recording. The drives are also tested for compatibility with a wide range of leading surveillance systems and chipsets, ensuring seamless integration.

Built for 24×7 Reliability & Long-Term Performance

WD Purple drives are engineered for durability and long-term reliability in always-on environments. With an MTBF of up to 1 million hours, tarnish-resistant components, and support for up to 16 drive bays, these drives deliver consistent performance even in harsh operating conditions.

Advanced firmware and vibration tolerance help maintain stable operation in multi-drive systems, making WD Purple an ideal choice for DVRs and NVRs used in homes, businesses, warehouses, and large surveillance installations.
