WD180PURZ WD Purple 18TB SATA 512 MB 3.5" Surveillance HDD

High-Capacity 3.5in SATA Surveillance HDD engineered for 24x7 streaming workloads with the WD180PURZ

The WD180PURZ is an 18TB 3.5in internal SATA HDD designed for continuous DVR/NVR write pipelines where sustained sequential throughput and deterministic latency are more important than short-burst IOPS. Its CMR recording model supports predictable block placement, helping RAID controllers maintain stable write behavior under multi-stream ingest and during rebuild operations.

Within modern x86 server and appliance platforms, the WD180PURZ integrates cleanly into SATA backplanes and PCIe-attached HBAs/RAID adapters, enabling scalable nearline tiers without consuming premium PCIe lanes required for NVMe. A 512MB cache and 512e sector format support efficient streaming buffers and broad OS compatibility, while the helium-filled 7200RPM design targets higher areal density and controlled thermals in dense chassis. For surveillance retention, cold archive, and capacity-oriented arrays, the WD180PURZ prioritizes endurance for 24x7 duty cycles over encryption offload, as it is not a self-encrypting drive.

Why Choose the WD180PURZ?

The WD180PURZ delivers a pragmatic density-to-slot profile for recording farms and nearline repositories, reducing bay count and cable complexity while keeping a standard SATA operational model. With 1.5M hours MTBF and CMR media characteristics, the WD180PURZ supports reliable scale-out pools and RAID sets where rebuild predictability and sustained write acceptance are primary design constraints.

WD designs Purple-class drives around continuous streaming integrity, vibration-aware operation in multi-drive enclosures, and firmware behavior aligned to long-duration sequential workloads. This engineering approach helps the WD180PURZ remain stable in always-on surveillance environments and capacity tiers that must meet data centre uptime expectations.

Key Applications:

• DVR/NVR video surveillance storage
• 24x7 multi-stream recording arrays
• Nearline SATA archive tiers
• Cold storage and retention pools
• CMR-based RAID capacity expansion
