Western Digital WD11PURZ – 1TB 5400 RPM SATA 6Gb/s 3.5-Inch Surveillance Hard Drive (WD Purple)
The Western Digital WD11PURZ is a 1TB WD Purple surveillance-class hard drive built for continuous video recording in small to mid-size CCTV and IP camera installations. It suits system integrators and distributors sourcing entry-capacity storage for NVR/DVR environments, where AllFrame technology helps reduce frame loss during multi-camera writes. Note that sustained performance reflects its 5400 RPM (IntelliPower) spindle class, which is positioned for reliability and workload efficiency rather than high-throughput enterprise applications.

Good to know
- Designed for surveillance NVR/DVR systems; confirm your recorder’s firmware compatibility and maximum supported capacity before deployment.
- Within the WD family, Purple targets surveillance workloads (sequential write-heavy, 24/7 operation) — distinct from WD Blue (desktop) and WD Red (NAS) positioning; capacity, cache, and camera-count support vary across the Purple range.
- As an export-focused trading supplier, we recommend verifying lot numbers, regional power standards for enclosures, and your system integrator’s warranty process before bulk ordering.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
