Western Digital Purple 500GB Surveillance HDD

WD Purple 500GB Drive

The Western Digital Purple 500GB hard disk targets continuous video write workloads in DVR and NVR systems. This 3.5-inch surveillance-class drive handles multi-stream recording from IP and analog cameras without desktop-grade duty-cycle limits. Five hundred gigabytes provides economical retention for small installations and backup tiers on larger arrays.

WD Purple firmware optimizes write caching and error recovery for always-on security environments. The drive supports up to dozens of HD camera streams on compatible recorders when paired with appropriate RAID or standalone configurations. SATA interface ensures plug-in compatibility with mainstream Dahua, Hikvision, and generic NVR chassis.

Small retail shops, branch offices, and residential systems often need modest local retention before cloud offload. A 500GB unit balances cost and capacity for four to eight camera deployments at standard bitrates. Integrators stock this SKU for quick field replacements when legacy recorder disks fail.

Western Digital AllFrame technology reduces frame loss when multiple streams arrive simultaneously. Thermal and vibration specs suit rack-mounted NVRs and standalone tower recorders in utility closets. Low power draw limits heat buildup in sealed enclosures without active cooling.

SMART monitoring attributes report reallocated sectors and temperature trends to maintenance dashboards. The PURX model suffix identifies the current surveillance-optimized product generation for procurement audits. Shipment packaging includes standard anti-static protection for warehouse and van inventory.
