Toshiba have unveiled 18TB hard drives in the N300 NAS hard drive and X300 performance hard drive line.

Both drives are 9-disk helium-sealed units featuring Toshiba’s Flux Control – Microwave Assisted Magnetic Recording (FC-MAMR) technology.

By using FC-MAMR, Toshiba managed to boost drive density by 12.5 percent.

For those with high storage needs, the 18TB N300 is a 7200 RPM 3.5-inch SATA high-endurance drive specifically designed for the rigors of 24/7/365 use in NAS boxes and other storage systems.

The 12TB-18TB N300 drives feature a helium-filled design for low-power consumption.

The drive features a 512MB buffer, can hit a data transfer rate of 281 MB/s, and is good for workloads up to 180 TB/year and an MTTF of 1,200,000 hours.

For those with an eye to performance, the 18TB X300 is a 7200 RPM 3.5-inch SATA high-performance drive.

This drive is aimed squarely at PC gamers, graphic designers, and other users with big storage requirements.

This also features a 512MB buffer rated for an MTTF of 600,000 hours.

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.
