Toshiba pushes N300 and X300 Hard Drive storage capacity to 18TB


Toshiba Electronics Europe GmbH has added new 18TB models to its N300 NAS Hard Drive and X300 Performance Hard Drive portfolios. Both new drives incorporate the company’s game-changing Flux Control - Microwave Assisted Magnetic Recording (FC-MAMR) technology, which was announced earlier this year.

With FC-MAMR a “Spin Torque Oscillator” (STO) is used to better control and effectively focus the magnetic flux generated in the hard disk drives (HDDs) write head. The focused flux allows more accurate writing operation leading to a smaller magnetic area per bit and higher data densities compared to the previous generation of CMR HDDs.

Use of FC-MAMR has led to the drive density being raised by an extra 12.5% - thereby adding 2TB[1] per disk to the capacity of Toshiba’s previous 16TB models[1]

The new N300 and X300 drives come in an industry-standard 3.5-inch[2] format enclosure but utilise a proprietary 9-disk Helium-sealed design. Toshiba Group’s advanced laser welding techniques keep the Helium securely sealed inside. 

The N300 Series is highly optimised for home office and small business network-attached storage (NAS) and private cloud storage applications, with up to 8 drive bays being accommodated[3]. These drives deliver 7200rpm performance and have integrated RV sensors to compensate for the effects of rotational vibrations. Designed for reliable 24/7 operation and offering a meantime to failure rate (MTTF) of 1.2 million hours, they attain a workload[4] rating of up to 180TB/year. 

Intended for PC and high-end desktop workstations, gaming consoles and home media equipment, the X300 Series drives also deliver 7200rpm performance. Their drive stabilisation mechanisms result in improved operational reliability, plus Toshiba Group’s cache technology optimises cache allocation during read/write so as to provide high-level performance in real time.

N300 Series drives all come with a 3-year limited warranty, while the X300 Series drives have a 2-year limited warranty. The new 18TB N300 and X300 models are expected to be available in Q4 2021.

[1] Definition of capacity: Toshiba defines a megabyte (MB) as 1 000 000 bytes, a gigabyte (GB) as 1 000 000 000 bytes and a terabyte (TB) as 1 000 000 000 000 bytes. A computer operating system, however, reports storage capacity using powers of two for the definition of 1GB = 230 = 1 073 741 824 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content. Actual formatted capacity may vary.

[2] "3.5-inch" means the form factor of Hard Drives. They do not indicate drive's physical size.

[3] As for "Drive Bays Supported", please contact your solutions provider because the compatibility with the host device will vary based on the RAID system.

[4] Workload is a measure of the data written, read or verified by commands from the host system over a calendar year.
