    24/7 Reliability

    Whether you’re hosting a cloud, sharing files between workgroups or powering a high-traffic network, the N300 NAS hard drive delivers advanced reliability supporting workloads of up to 180 TB per yearand MTTF of up to 1 million hoursto help keep your NAS system running 24/7.

    The Speed to Stay Ahead

    Designed to handle high data workloads in a multi-RAID NAS environment, the N300 delivers fast data transfer speed, thanks to the large cache size and 7200 RPM speed.  Plus, Toshiba’s cache technology helps optimize cache allocation during read/write cycles to provide high performance in real time.

    Data Protection

    Built-in Rotational Vibration sensors and heat prevention controls detect and compensate for shock, rotational vibration, and heat, while error recovery control helps reduce critical downtime – so you can access your data when you need it.

    Helium-Sealed Design

    The 12TB1 and 14TB1 models utilize a Helium-Sealed design to deliver increased storage density and lower operating power profile*.  This helps reduce the total cost of ownership of the drives as your server system scales*.

    The helium-filled N300 models run more efficiently than a standard air-filled model, delivering a smoother drive performance for your NAS system.  The helium models reduce acoustic output (in idle mode) by up to 40%* and operating power consumption by up to 30%*.

    * compared to the N300 10TB model.
