WD 4TB 3.5" 128MB SATA Purple Surveillance

Features

The WD Purple Surveillance WD44PURZ 4 TB hard drive is built specifically for video surveillance systems that require continuous 24/7 operation. It handles heavy workloads from constant multi-camera video recording without performance degradation.

AllFrame technology stabilizes data flow and reduces the chance of dropped frames during intensive write operations. The drive supports simultaneous recording from up to 64 HD cameras, making it suitable for medium to large-scale surveillance setups.

The 128 MB cache enables efficient handling of read/write requests in multi-stream environments. Robust mechanics and firmware optimizations lower error rates and extend operational lifespan.

The 3.5-inch form factor and SATA interface provide broad compatibility with most DVRs and NVRs. Low power consumption and vibration control are beneficial in multi-drive enclosures.

A 36-month warranty reflects the manufacturer's confidence in the drive's durability under proper surveillance use conditions.
