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 HDD stocked specifically for our B2B channel — resellers, system integrators, and IT procurement teams building NVR/DVR solutions for small to mid-size CCTV deployments. AllFrame technology reduces frame loss during simultaneous multi-camera writes, making this model a reliable line item for recurring surveillance project bids at the entry-capacity tier. Buyers should note the 5400 RPM (IntelliPower) spindle class is engineered for 24/7 sequential write workloads and workload efficiency, not high-throughput enterprise storage.

Units are sourced through authorized channels with batch and lot consistency maintained across orders, which simplifies firmware matching and RMA traceability for volume deployments. Stock levels for this SKU are confirmed at time of order; we support both spot purchases and scheduled repeat orders for integrators with rolling project pipelines. Standard export documentation is provided, and the product carries CE, FCC, and RoHS compliance for overseas distribution.

Procurement guidance

• Purpose-built for surveillance NVR/DVR environments; integrators should confirm recorder firmware compatibility and maximum supported drive capacity prior to bulk deployment.
• Within the WD portfolio, Purple is positioned for sequential write-heavy, round-the-clock video workloads — distinct from WD Blue (desktop) and WD Red (NAS) — with capacity, cache, and camera-count ratings varying across the Purple lineup. Ask our sales team about cross-SKU bundling for mixed-capacity projects.
• We recommend verifying lot numbers, regional power standards for enclosures, and your own warranty pass-through process before placing bulk orders; our team can supply batch data on request.

Whether you are a distributor replenishing inventory or a system integrator quoting a multi-site CCTV rollout, our export team can align volume, lead time, and shipping terms to your project schedule. For current stock confirmation and pricing, request a wholesale quote.
