Mx11, a new family of helium-sealed high-capacity HDDs that includes the MG11 Series with capacities of up to 24 TB using conventional magnetic recording (CMR) and the MA11 Series with up to 28 TB capacities with shingled magnetic recording (SMR), is currently in development for use at hyperscalers and data centers, Toshiba has announced. Sample shipments of the MG11 Series will start this month, with those for the MA11 Series coming later, in the fourth calendar quarter of this year.
Key features for the MG11 Series include:
- “Up to 24 TB capacity.”
- “Conventional Magnetic Recording (CMR) for broad compatibility.”
- “Toshiba 2nd generation Flux Control Microwave-assisted Magnetic Recording (FC-MAMR) Technology.”
- “Industry-leading 10-disk helium-sealed design for superior storage density.”
- “Industry Standard 3.5-inch 26.1 mm height Form Factor.”
- “7200 rpm Performance.”
- “Lower operational power profile, providing excellent power efficiency (W/TB) for better TCO.”
- “550 Total TB Transferred per Year Workload Rating.”
- “Sanitize Instant Erase (SIE) option model and Self Encrypting Drive (SED) option model.”
Toshiba on its new hard drives:
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 rapidly scale storage density within existing infrastructure. Built with a 1GiB buffer, the new 24TB HDD is faster 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 to 24TB, the MG11 Series is available in 22TB, 20TB, 18TB, 16TB and 14TB capacities with sanitize instant erase (SIE) and self-encrypting drive (SED) options for enhanced security.
The MA11 Series achieves 2.8TB per disk using SMR technology. The MA11 Series host-managed SMR increases drive capacity by overlapping the physical tracks on the disk during write operations. Data centers with software that can optimize the MA11 Series host-managed SMR 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.
