Unleashed: 14TB Helium-filled HDD For Enterprises


Toshiba has launched what it claims the world’s first enterprise 14TB HDDs (hard disk drives) using Conventional Magnetic Recording (CMR) rather than the slower shingled magnetic recording (SMR) technology. The 14TB drives use an innovative 9-disk, helium-sealed design to deliver massive capacity optimised to meet the storage needs of large hyperscale and cloud companies.

Using a 9-disk, helium-sealed design, the new MG07ACA Series provides the power-efficient capacity and storage density needed by cloud-scale and enterprise storage solution providers to achieve their TCO objectives.

The MG07ACA-series drives, Toshiba says, are the first 14TB drives to use CMR technology. The new HDDs are potecntially faster than competing SMR drives which use a shingled arrangement of tracks that slow down the write process. To overcome the limitations of SMR, the MG07ACA stacks a lot of disks inside a helium-sealed enclosure.

“We have raised the bar with the new MG07ACA Series 9-disk helium-sealed design,” said Akitoshi Iwata, Vice President of Storage Products Division, Toshiba Electronic Devices and Storage Corporation. “By utilizing an innovative design, we continue to improve the benefits that high-capacity disk storage can deliver to our broad global customer base.”


The new MG07ACA Series features both 14TB 9-disk and 12TB 8-disk models.

The drives support a SATA 6Gbit/s interface and 7,200rpm access performance.

The 9-disk 14TB models are said to achieve a 40% increase in maximum capacity over previous MG06ACA 10TB models. Additionally, the 14TB models improve power efficiency by over 50% (W/GB).

“While enterprise server and storage customers realize that shingled magnetic recording (SMR) technology can improve HDD capacity, the adoption of SMR HDD products into server and storage systems is a transition that will take several years,” according to John Rydning, Research Vice President for hard disk drives at IDC. “Toshiba Electronic Devices & Storage’s new helium-sealed enterprise HDD is the world’s first 14TB of storage capacity using conventional rather than shingled magnetic recording technology, giving enterprise customers the highest capacity HDD available in the market today for existing server and storage system architectures.”
