Both the 6TB MG04ACA and MG04SCA models offer Toshiba persistent write cache technologies, designed to help protect against data loss in the event of sudden power loss, while also helping to improve performance and data reliability. Model options supporting SAS and SATA commands to enable sanitize "instant" cryptographic erase (SIE) are also available. Spinning at 7,200 rotations per minute (RPM), the MG04SCA and MG04ACA deliver nearline-class seek performance to improve application response times. At 6TB, the higher capacity per spindle saves rack space and reduces the footprint and operational burden of business-critical servers and storage systems to help optimize total cost of ownership in high-density scale-out environments. The 6TB models provide 50 percent better power efficiency (watts per terabyte) than the previous 4TB drive generation.
