WD240PURP WD Purple Pro 24TB SATA 512 MB 3.5" Surveillance HDD

High-Capacity 3.5in SATA Surveillance HDD for 24/7 Recording and Retention with WD240PURP

WD240PURP is a 24TB 3.5in internal HDD engineered as a capacity-first tier for DVR/NVR arrays and edge retention nodes where continuous sequential writes and predictable recovery behavior are more important than low-latency IOPS. Deployed behind modern x86 NVR servers or storage gateways, WD240PURP complements CPU- and GPU-accelerated video analytics by sustaining ingest and long retention without consuming PCIe lanes or memory resources reserved for compute.

The SATA architecture of WD240PURP fits dense backplanes and HBAs while keeping expansion slots available for NICs, GPUs, and capture/AI accelerators. CMR recording supports consistent write performance under 24/7 duty cycles, and the 512MB cache helps absorb bursty camera streams and metadata updates. Advanced Format 4Kn with 512e compatibility enables alignment with current file systems and NVR software stacks, while TLER support improves RAID/NVR resilience by bounding error recovery time to protect array responsiveness.

Why Choose the WD240PURP?

WD240PURP delivers a practical density-to-rack-unit profile for surveillance and bulk capacity tiers, reducing drive count per retained TB and simplifying enclosure planning. WD240PURP is optimized for continuous recording reliability, with enterprise-aligned behavior in RAID environments and a scalability profile suited to multi-bay NVRs, JBOD shelves, and edge sites where service windows are limited and predictable rebuild behavior is required.

WD applies a workload-led engineering approach focused on sustained operation, controlled error recovery, and compatibility with common SATA backplanes and RAID controllers. With a 2.5 million hour MTBF design target, WD240PURP supports modern data centre expectations for uptime-oriented storage tiers and consistent operational characteristics across large fleets.

Key Applications:

• DVR/NVR video surveillance arrays
• 24/7 continuous recording repositories
• Edge and SMB long-retention storage
• Archive and capacity tiers for sequential workloads
