Toshiba has introduced N300 and X300 series of high-end, large-capacity mechanical hard drives for NAS and desktop enthusiasts.
Both the series are available in two models: 12TB and 14TB and use a helium-sealed design in the casing of 3.5 inches. The drives have the mechanical components which according to the company made them deliver increased storage density with a lower hard drive operating power profile. As the drives are filled with the Helium and to protect it from leaking the Toshiba uses a laser welding technology to seal the hard drive case.
Both the models 12TB and 14TB operate at 7,200rpm. In terms of performance, the 12TB continuous transmission speed is up to 253MB/s, and 14TB is up to 260MB/s. The interface is standard SATA3 6Gbps, 7200 rpm, 256MB cache, and consumes about 9W.
In terms of reliability, the N300 NAS and X300 models come with 3 years warranty. There are additional motors on the top and bottom, which Toshiba calls “Stable Platter Technology” to minimize vibrations by stabilizing the motor shaft.
In terms of difference, the N300 series exclusively provides 8-way shock sensor to ensure stability under 7×24 hours, with an annual write byte of 180TB and an average time between failures of 1 million hours.
The N300 NAS Hard Drive series is designed for use in high-performance personal, home office and small business network attached storage applications such as for scalable RAID systems. While the X300 Performance Hard Drive series designed for creative and professional applications including graphic design, animation, photo and video editing, and PC gaming.
Toshiba said that two hard drives are scheduled to go on sale at the end of this month, and the suggested retail price has not yet been announced.
