Toshiba launches first 14Tbyte HDD with conventional magnetic recording

Toshiba Electronics Europe believes it has introduced the first enterprise 14Tbyte conventional magnetic recording (CMR) HDD. The MG07ACA series uses a nine-disk, helium-sealed design. The MG07ACA series HDD provides the power-efficient capacity and storage density needed by cloud-scale and enterprise storage providers, says Toshiba.

According to Akitoshi Iwata, vice president of Storage Products Division, Toshiba Electronic Devices and Storage Corporation, the company has set a new level with the introduction of the MG07ACA series nine-disk helium-sealed design. The design improves the benefits that high-capacity disk storage can deliver, he added.

The MG07ACA series features both 14Tbyte nine-disk and 12Tbyte eight-disk models. The helium-sealed 3.5-inch mechanical design realises better storage density and a lower HDD operating power profile than the previous MG06ACA series for optimal total cost of ownership (TCO) in cloud-scale infrastructures. The MG07 series also uses Toshiba Group’s laser welding technology to ensure the helium remains securely sealed inside the drive enclosure. The drives support a SATA 6Gbit/s interface and 7,200rpm access performance. The nine-disk 14Tbyte models achieve a 40 per cent increase in maximum capacity over previous MG06ACA 10Tbyte models. The 14Tbyte models improve power efficiency by over 50 per cent (W/Gbyte, calculated based on active idle power consumption divided by formatted capacity).

The capacity will help customers meet the storage needs of large hyperscale and cloud companies. The nine-disk platform paves the way to achieving higher capacities in future product generations.

“Toshiba Electronic Devices & Storage’s new helium-sealed enterprise HDD is the world’s first 14Tbyte 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,” said John Rydning, Research Vice President for hard disk drives at analyst firm, IDC. 

He added: “While enterprise server and storage customers realise 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”.
