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 continuous operation 24 hours a day, 7 days a week, which distinguishes them from standard computer drives. Thanks to the massive 3 TB capacity, the user gains the space necessary to store high-quality video recordings from many cameras simultaneously.

Specification

Another benefit is energy efficiency and resistance to operating conditions inside recorders. WD Purple drives are characterized by low power consumption, which is important for systems operating without interruption, and high operating culture (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 invest in the security of your data and the certainty that not a single second of recording will be lost.

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

General Parameters

AllFrame 4K Technology

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