The Toshiba MG Enterprise Disk is a new higher capacity lineup for high-end desktop, data center and NAS users. The MG Enterprise disks are helium filled to be able to afford more platters in the assembly, The industry has been migrating to helium in order to more widely design 9 plate class hard disks compared to the 4 plates seen in air based designs.

As Big Data drives demand for more distributed storage in the cloud and on premises, enterprise server and storage systems need to be built using trusted solutions. Toshiba’s Enterprise Capacity Hard Drive – MG Series offers formatted capacities as high as 14 TB with interface options including SATA and SAS and delivers 24/7 operation at a workload of 550 TB/year. The MG Series is ideal for enterprise storage array and industrial server and storage systems. It provides the capacity and advanced technologies to meet the special demands of datacenter and cloud-scale infrastructures.

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 minimising 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.

Most file systems over the last decade can handle the 4K sector format fine. The emulated 512 sector supports legacy needs. The problems come from database engines with a read/modify/write with a smaller block size. SSD products are not impacted by 512e like a hard disk which would be slowed packing small sectors. For a gaming box with a huge library NTFS can leverage 4K sectors easily. The nature of the workload has to be considered when deploying storage.

The MG08 and MG07 Conventional Magnetic Recording (CMR) HDDs use a 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 MG08 and MG07 Series also utilise Toshiba Group’s laser welding technology to ensure the helium remains securely sealed inside the drive enclosure. The MG08 Series features a 16 TB 9-disk model, while the MG07 Series features both 14 TB 9-disk and 12 TB 8-disk models.


Servers tend to use dual power supplies to keep a NAS operational. Desktop uses should consider using high-end power supplies to endure clean power delivery. In use hosting actively updated games the MG series are rock solid. The performance is optimal with daily disk optimization to migrate the variable parts away from the consolidated stable files.
