Toshiba Announces 8TB HDD For Enterprise

Toshiba America Electronic Components, Inc. announced that it is now shipping in volume its highest capacity HDD to date, the MG05ACA800. New to the MG series of HDDs, the MG05ACA800 has increased its capacity by 33%, or from 6TB to 8TB, from the previous MG04ACA model. The new 8TB HDD is a SATA 6.0Gbit/s drive that Toshiba claims to have a 12% increase in sustained transfer rate performance over the previous model.

Across the industry data is exploding. As opposed to building larger data centers and increasing footprint, companies would rather increase density, being able to place more data within the same footprint. The new MG05ACA800 aims to do just that. The drive is standard form-factor of 3.5” and SATA interface, which enables businesses to drop in the new drives and gain capacity over their previous drives. Toshiba states that the drive’s performance characteristics match-up well with requirements for applications such as software-defined storage infrastructures, public and private cloud deployments, digital archives and disk-based backup, and data protection solutions.

The new 8TB drive is designed to operate 24x7. It provides a 550TB transferred-per-year rated workload, with a 2,000,000-hour MTTF rating, and has power management features that will optimize operating costs and operating environments during off-peak activity periods. The MG05ACA800 will be the first Toshiba SATA drive to support the new industry-standard host-initiated power-disable feature for improved device management capability.

  • Form Factor: 3.5”
