toshiba mb09 18tb

Toshiba has now launched a new 18TB model of the popular MN09 series hard disks. The new 18 TB model will likely be popular with NAS users galore.

High growth in data creation is driving demand for higher storage capacities, and work-from-home customers need fast access to data and the ability to archive and share data in private cloud environments. The 18 TB MN09 delivers greater storage capacity and power efficiency to meet the growing needs of storage customers.
MN09 is a 9-disk helium-sealed conventional magnetic recording (CMR) drive that leverages Toshiba’s new innovative Flux Control Microwave-Assisted Magnetic Recording (FC-MAMR ) technology. FC-MAMR advances CMR capacity to 18 TB and delivers increased density per platter over previous designs. The MN09 is the 3rd generation to use Toshiba’s pioneering 9-disk helium-sealed mechanical design.
MAMR technology is one solution that extends HDD data capacities. The ability of HDD using a new MAMR head to significantly improve the write ability of the Microwave Assisted Switching (MAS) effect has been developed recently. Toshiba will continue to satisfy market demand and to advance CMR drive data densities with MAMR technology.
MN09 is engineered for 24/7 operation and has a workload rating of 180 TB/year. Up to eight drive bays are supported by the NAS 3.5-inch drive. The Synology 8-disk NAS units are the primary market for the MN09 series. For heavier workloads the Toshiba MG09 disks are available.

The 7200RPM 18 TB NAS drive is designed with a 512 MB buffer and delivers a consistent high level of performance with a sustained transfer rate of 268 MiB/s, making it the preferred choice of home offices and small businesses. The MN09 18 TB is available now.

Earlier Seagate introduced new 20TB hard disks to match WD’s earlier models. The Toshiba disk is intended for NAS users and other models are expected presently.
