Purpose-built surveillance storage

The WD Purple WD140PURZ is a 14TB 3.5 inch internal hard drive designed for continuous video recording workloads. It uses a SATA 6.0Gb/s interface and spins at 7200 RPM with a 512MB cache to handle multiple simultaneous camera streams. The bare-drive packaging suits system integrators and DIY builders expanding or replacing storage in network video recorders.

Ideal for NVR expansion, not for general desktop use

This drive targets installers and owners of surveillance systems that write large sequential data around the clock. It is not suited for users seeking a primary operating-system drive, low-noise desktop storage, or portable external backup, where solid-state or lower-RPM drives are more appropriate.

SATA 6.0Gb/s interface determines host compatibility

The drive connects via a standard SATA 6.0Gb/s port, so the host controller or NVR must provide a matching SATA data and power connection. No other interface or protocol is supported, and the 3.5 inch form factor requires a compatible drive bay or enclosure.

商品問答

How does the 14TB capacity translate to usable space once the drive is formatted in a surveillance system?

The drive provides 14TB of raw capacity; after formatting the operating system will report slightly less, but the full 14TB is available for continuous video recording workloads.

What does the SATA 6.0Gb/s interface mean for real-world throughput in a 7200rpm surveillance drive?

The SATA 6.0Gb/s link caps the theoretical maximum at 6.0Gb/s, while the 7200rpm platters and 512MB cache deliver sustained sequential speeds suited to multiple high-definition camera streams.

Will this 3.5-inch drive fit a standard surveillance NVR bay with the listed dimensions?

The drive measures 147.00mm long, 101.60mm wide and 26.10mm high, matching the standard 3.5-inch form factor used in most NVR and desktop drive bays.
