WD Purple 2TB Surveillance Hard Drive (WD23PURZ)

The WD Purple WD23PURZ delivers reliable 2TB surveillance storage purpose-built for 24/7 NVR and DVR systems. With 5400 RPM rotational speed, 64 MB of cache, and a 180 TB/year workload rating, this drive handles continuous video ingest in retail, office, and small-to-medium business deployments. Western Digital's AllFrame technology reduces frame loss during simultaneous multi-stream recording, supporting Up to 64 cameras for cost-effective surveillance archives.

Key Features

2TB capacity for extended video retention—weeks to months of continuous recording on standard surveillance configurations

5400 RPM rotational speed with 64 MB of cache for sustained sequential write performance during multi-camera ingest

180 TB/year workload rating—designed for the duty cycle of standard desktop drives, validated for round-the-clock surveillance operation

1.0 million hours MTBF reliability rating for mission-critical security deployments where uptime matters

AllFrame technology reduces frame drops and pixelation during high-bandwidth recording, especially with H.264/H.265 multi-stream feeds

SATA 6 Gb/s interface with 175 MB/s sustained transfer rate for seamless integration with standard NVR/DVR controller boards

3.5-inch form factor compatible with virtually all surveillance NVRs, DVRs, and rackmount video storage chassis

Up to 64 cameras with Up to 16 AI streams—engineered for AI-ready surveillance workloads with deep-learning analytics streams

Operating temperature 0°C to 65°C—suitable for unconditioned IT closets, server rooms, and indoor surveillance enclosures

3-year limited warranty backed by Western Digital's manufacturer support

Built for Surveillance Workloads

WD Purple drives are the surveillance-grade complement to consumer Blue drives and enterprise Red NAS drives. Where a desktop drive would fail under sustained 24/7 write workloads, the Purple line is validated for 180 TB/year of continuous writes and 1.0 million hours MTBF—matching the duty cycle of NVR/DVR recording in retail, office, multi-tenant residential, and small-to-medium business deployments.

AllFrame technology is WD's answer to the pixelation and dropped frames that plague consumer drives in surveillance applications. Streaming-mode firmware prioritizes write completeness over benchmark IOPS, holding video frames in cache and writing them sequentially without competing with system-level read operations. For multi-camera systems running H.264 or H.265 compression, this directly translates to fewer corrupt clips and cleaner playback.

The WD23PURZ integrates with virtually any standard 3.5-inch SATA bay—Hanwha, i-PRO, Vivotek, Speco, Geovision, and most generic NVR/DVR controllers. Drive trays, caddies, and SATA backplanes use the standard 3.5-inch form factor. SATA 6 Gb/s is backward-compatible with SATA II (3 Gb/s) and SATA I (1.5 Gb/s) controllers, though sustained throughput is highest on a SATA 6 Gb/s host.

Choose the WD23PURZ when you need cost-effective 2TB surveillance storage with manufacturer-validated workload ratings. For large multi-site deployments, AI-enabled NVRs, or environments approaching 550 TB/year of writes, step up to the WD Purple Pro line for the higher MTBF and AI-stream capacity.
