At this capacity the D300 PRO is rated for 3 drive writes per day (DWPD) endurance, translating to roughly 21,024TB of total bytes written over its warranty life, and includes power-loss protection (capacitor-backed circuitry that flushes in-flight data to flash if power cuts out unexpectedly, preventing data corruption) and AES 256-bit hardware encryption for data-at-rest security. Hiksemi (a storage sub-brand of Hikvision) backs the D300 PRO with a 2-million-hour MTBF rating and a 5-year warranty, positioning it as a genuine enterprise/datacentre drive suited to database servers, virtualization hosts and other write-heavy business workloads where reliability and consistent endurance matter more than absolute lowest cost per gigabyte. Hiksemi is positioned as Hikvision's dedicated storage sub-brand, selling enterprise and consumer SSDs alongside Hikvision's better-known surveillance camera and recorder business, and the D300 PRO line is its flagship SATA enterprise offering.
