The Toshiba MG03ACA/MG03SCA series HDDs are designed to support enterprise applications where reliability, high capacity, and performance are required. The series is ideally suited for data archives and digital records storage, entry and business critical server and storage systems, disk backup systems—including remote sites for data protection and business continuity, and tiered virtual infrastructure for public and private cloud deployments (IaaS and PaaS).

The optional SATA self-encrypting (SED) models support fast and secure cryptographic erase using both the latest T13 SANITIZE crypto-scramble protocol and the older T13 ATA Security Erase command protocol. The optional SAS SED models support both the T10 SANITIZE crypto-erase feature and the Trusted Computing Group Enterprise Security Sub-Classification protocols. These proven, industry-standard security technologies support “nearly instantaneous” cryptographic-erase of user data to enable fast and secure device retirement or redeployment. Using SEDs can eliminate the need for lengthy data overwrite cycles and reduce IT department expenses associated with secure data destruction and device sanitization.
