LTS DHWD202PURP WD Ultrastar 20TB Surveillance Hard Disk Drive, 7200 RPM Class SATA 6 Gb/s 256MB Cache 3.5 Inch

The LTS DHWD202PURP is a 20TB Ultrastar DC HC555 enterprise-class hard drive offering high-capacity, high-endurance storage for large-scale surveillance and data center environments. Built on HelioSeal technology with a helium-filled enclosure design, the Ultrastar DC HC555 delivers a 2.5 million hour MTBF rating and a 550TB/year workload rating, making it one of the most reliable and durable options available for always-on surveillance and AI storage workloads.

Spinning at 7200 RPM with a 512MB cache and a SATA 6 Gb/s interface, this 3.5-inch drive supports both 512e and 4Kn sector formats for compatibility across legacy and modern storage platforms. With 20TB of raw capacity, the DC HC555 is well-suited for enterprise NVRs, large-site multi-camera deployments, and video analytics servers requiring extended retention periods without drive swaps.

Key Features:

• 20TB storage capacity; enables extended video retention for large multi-camera enterprise surveillance deployments on a single drive.
• HelioSeal helium-filled design; reduces internal turbulence for lower power consumption, cooler operation, and higher areal density versus air-filled drives.
• 2.5 million hour MTBF and 550TB/year workload rating; built for the continuous write demands of enterprise NVR and AI analytics environments.
• 7200 RPM with 512MB cache; delivers high throughput for simultaneous multi-stream recording and analytics I/O.
• 512e/4Kn sector support; compatible with both legacy 512-byte sector systems and modern 4K native storage platforms.
• SATA 6 Gb/s interface; integrates with enterprise NVRs, storage servers, and surveillance appliances.
• 3.5-inch form factor; fits standard enterprise NVR and storage enclosure drive bays without adapters.
