Toshiba Announces 24TB CMR and 28TB SMR Enterprise Hard Disk Drives

Toshiba Electronics Europe GmbH (Toshiba) announces the Mx11 family of helium-sealed Enterprise Capacity HDDs. The Mx11 family includes the MG11 Series, which provides capacities of up to 24TB using conventional magnetic recording (CMR), and the MA11 Series, which offers up to 28TB capacities with shingled magnetic recording (SMR).

The new Mx11 family is designed to deliver new levels of density and power efficiency to customers tasked with controlling (or managing) operational costs while meeting the relentless demands of data growth. Built on a common architecture, both products feature a 10-disk, helium-sealed, standard 3.5- inch 7,200rpm design that leverages Toshiba’s innovative flux control microwave assisted magnetic recording (FC-MAMR™) technology. Engineered for higher performance and 24/7 reliability, the Mx11 family is designed with a 1GiB buffer, a workload rating of 550TB per year, an MTTF/MTBF of 2.5 million hours, and an AFR of 0.35%.

The MG11 CMR HDD Series enables cloud, data center, and enterprise storage customers to scale storage density within existing infrastructure rapidly. Built with a 1GiB buffer, the new 24TB HDD is faster[6] than its predecessor, with an approximately 9% faster maximum sustained transfer speed of 295MiB/s.

With a choice of 6Gbps SATA or 12Gbps SAS interfaces, the MG11 Series fits seamlessly into any data center to support data storage, online backup and archive, and video surveillance applications. In addition, for enhanced security, the MG11 Series is available with sanitize instant erase (SIE) and self-encrypting drive (SED) options.

The MA11 Series achieves 2.8TB per disk using SMR technology. The hostmanaged SMR increases drive capacity by overlapping the physical tracks on the disk during write operations. Data centers with software that can optimize such a design will benefit from improved cost efficiencies through higher storage densities. The new MA11 Series is available in 28TB and 27TB capacities with a 6Gbps SATA interface and with SED options for enhanced security.
