Technology innovation delivers efficiency and performance for traditional IT systemsUltrastar DC HC320 is based on a proven 5-disk air platform design that uses conventional magnetic recording (CMR) technology in a 3.5-inch large form factor. The DC HC320 delivers more capacity, advanced performance and uses slightly larger-diameter media. It features a dual-stage micro actuator to enhance head positioning accuracy for better drive performance. Write performance gains are also supported by Western Digital's media cache architecture, a disk-based caching technology that provides a large cache area on the disk, which also improves reliability and data integrity during unexpected power loss. Finally, the addition of flash-based non-volatile cache (NVC) helps to improve write performance. The Ultrastar DC HC320 also includes a Rebuild Assist feature, which helps to dramatically reduce RAID rebuild times and maintain system performance during the rebuild process.Data security with trusted quality and reliabilityCompliance and privacy requirements drive the need for increased data security. Ultrastar DC HC320 helps to protect data from unauthorized use by offering security and encryption options. It offers hardware-based encryption options, which include both Sanitize Crypto Scramble, Erase functionality and TCG encryption (Trusted Computing Group, Enterprise SSC).
