Using the world’s first 9-disk Helium-sealed design, the MG07ACA Enterprise Capacity SATA HDD provides up to 14TB of conventional magnetic recording (CMR) capacity and 7,200 rpm performance. The industry-standard 3.5-inch form-factor integrates easily into cloud-scale storage infrastructure, business-critical servers and storage, and File and Object storage solutions.

The MG07ACA Series utilizes Toshiba precision laser welding technology to seal helium inside the 9-disk mechanics for the life of the drive. The helium-sealed design reduces aerodynamic drag to deliver a lower operational power profile, helping to achieve TCO objectives for cloud-scale and software-defined data center infrastructure.


The massive 14TB and 12TB model capacity is delivered using proven CMR/PRM recording technologies providing optimum compatibility and data reliability. Equipped with SATA 6.0 Gbit/s interface, the MG07ACA models integrate easily into standard 3.5-inch SATA drive bays to help reduce the footprint and operational burden of cloud-scale storage infrastructure, and business critical servers and storage systems.

Regular hard disk drives can impact the performance of a multi-bay system by generating 'knock-on' vibration. The MG Series ensures high reliability by minimizing vibration effects through their advanced control and sensing technology. Multiple sensors detect the slightest shock and built-in RV (Rotational Vibration) sensors compensate for any rotational vibration detected, eliminating the possibility of 'knock-on' vibration in multi-bay server systems.


Your data is critical so don't risk it. Toshiba's advanced technologies have been developed to add security and assurance to the enterprise user. With Persistent Write Cache Technology your data is safe in the event of an interruption in power supply during a write to the hard disk. Data is saved in the large flash-based cache and written to the disk when power is restored.


Toshiba’s innovative Stable Platter Technology minimizes vibrations by stabilizing the motor shaft at both ends. And that means improved tracking accuracy and maximum performance during read and write operations. In addition, Toshiba’s Dynamic Cache Technology, a self-contained cache algorithm with on-board buffer management, optimizes how the cache is allocated during read/write to provide the high-level performance demanded by real-time domains.


The MG07ACA Series, the world’s first enterprise 14 TB Conventional Magnetic Recording (CMR) HDD uses a 9-disk, helium-sealed design, providing the power-efficient capacity and storage density needed by cloud-scale and enterprise storage solution providers to achieve their TCO objectives. The MG07 Series also utilises Toshiba Group’s laser welding technology to ensure the helium remains securely sealed inside the drive enclosure. The MG07ACA Series features both 14 TB 9-disk and 12 TB 8-disk models.


Enterprise users need flexibility - the MG Series meets this need with a choice of 6 Gbit/s SATA and dual-port 12 Gbit/s SAS interface options as well as block size on demand (512e, 4Kn, 512n). Additionally, there are options for Toshiba hard drives with Self Encrypting technology or with Sanitize Instant Erase (SIE) technology, which means that in an instant all data is erased, without the need for overwriting the drive for hours.


Toshiba is renowned the world over for 50 years of leading innovation – and the power behind its range of hard drives is no exception. Designed for high capacity and excellent performance, you can be sure that Toshiba’s wealth of experience in hard drives is at work in your storage system.
