Toshiba-IMSourcing MG04ACA 6 TB Hard Drive

The MG04 series delivers impressive capacity and offers Toshiba persistent write cache technology

Toshiba Electronics Europe (TEE) announces the addition of 6TB[1] SATA and SAS models to its MG04 series of 3.5-inch form factor enterprise capacity class of hard disk drives (HDD). The new SAS interface models provide the benefits of 12Gbit/s[2] SAS transfer rates and enhanced power management features for seamless integration with the latest generation of data center infrastructure. The MG04 series is specifically designed for midline and nearline business critical workloads.

The new MG04 series 6TB models offer a 50 per cent[3] increase in max capacity from prior MG03 generation 4TB models and a 30 per cent[4] increase in sustained data rate. These enterprise HDDs support both industry-standard 4K native and 512e Advanced Format sector technologies for optimum performance in the latest generation servers and storage systems. Emulated 512e Advanced Format sector technology performs best in legacy applications requiring 512 sector lengths using aligned-write environments.

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.

"Our customers expect to benefit from the increased capacity, efficiency and performance made possible by the latest industry-standard interface and long sector technologies," said Martin Larsson, Vice President, Toshiba Electronics Europe, Storage Products Division. "These additions to the MG04 series deliver an impressive 6TB capacity and continue to provide the benefits of Toshiba's persistent write cache technology to enhance performance for business critical server and storage systems."
