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 18TB N300 delivers greater storage capacity and power efficiency to meet the growing needs of storage customers. 

The 18TB N300 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 18TB and delivers increased density per platter over previous designs. This is the 3rd generation to use Toshiba’s pioneering 9-disk helium-sealed mechanical design.

MAMR technology is the 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.

The 18TB N300 models are engineered for 24/7 operation and has a workload rating of 180TB/year[2]. Up to eight drive bays are supported by the NAS 3.5-inch[3] drive.

The 7200RPM 18TB N300 drive is designed with a 512MB buffer and delivers a consistent high level of performance with a sustained transfer rate of 268 MiB/s[4], making it the preferred choice of home offices and small businesses.
