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 systems뾦ncluding remote sites for data protection and business continuity, and tiered virtual infrastructure for public and private cloud deployments (IaaS and PaaS).With a top storage capacity of 4TB*, the Toshiba MG03ACA/MG03SCA HDDs utilize a traditional 3.5-inch form factor, enabling system builders to leverage 3.5-inch based storage chassis. The high-capacity, cost-effective models feature 7,200 RPM spin speed and leading-edge 6Gb/sec Serial Attached SCSI (SAS) and Serial ATA (SATA) interfaces.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.The series leverages the expertise and history of Toshiba in enterprise-class storage and offers similar features as traditional enterprise-class drives including 24 x 7 operation, Error Correction (ECC) and a 5-year warranty.
