Description

The Western Digital Purple series hard drive, model HDD-WD34PURZ, is a professional solution dedicated to closed-circuit television (CCTV) systems. Devices in this line have been designed for reliable, 24/7 continuous operation, which distinguishes them from standard desktop hard drives. With a massive 3 TB capacity, the user gains the space necessary to store high-quality video recordings from multiple cameras simultaneously.

Specification

Drive type: HDD Magnetic; Application: 24/7 video surveillance systems; Intended for: NVR, DVR recorders, video servers

A key advantage of this model is the unique AllFrame 4K technology. Combined with the ATA streaming transmission mechanism, this solution helps drastically reduce the phenomenon of dropped video frames and reduces image writing errors. This translates directly into the fluidity of the played-back material, which is critical when analyzing incidents. The drive has been optimized for operation with NVR and DVR recorders, performing excellently in environments with high data write intensity.

Another advantage is energy efficiency and resistance to operating conditions inside recorders. WD Purple drives are characterized by low power consumption, which is significant for systems working continuously, and high build quality (low noise and vibration levels). A workload rating of up to 180 TB per year guarantees longevity and stability, even in the most demanding property protection installations. By choosing WD Purple, you are investing in the security of your data and the certainty that not a single second of recording will be lost.

Capacity: 3 TB (3000 GB); Rotational speed: 5400 RPM class; Cache memory: 128 MB

General Parameters

Interface standard: SATA III (Serial ATA 6 Gb/s); Backward compatibility: Yes, SATA II; Throughput: Up to 600 MB/s

Capacity and Performance

The drive firmware optimizes video stream handling, minimizing write errors and frame dropping (pixelation), which is crucial in professional CCTV installations. AllFrame improves cooperation with the ATA transmission mechanism, which allows simultaneous support for up to 64 HD cameras. Thanks to this solution, surveillance systems become more reliable, and the played-back evidence material is characterized by the highest fluidity and lack of structural distortions.
