Toshiba’s 3.5-inch N300 NAS Hard Drive offers unprecedented reliability for NAS and other high-performance storage systems. It is optimized to meet the reliability, endurance, performance and scalability requirements of 24-hour x 7-day high-capacity storage for personal, home office and small business use. The N300 is available in capacities of up to 14 TB.

Designed for NAS

Through its contact with NAS manufacturers, Toshiba recognizes the need for high-reliability disks in support of modern data storage and retrieval demands including streaming, backup and archiving. The drive, which can support multi-RAID systems with up to 8 hard disk drives, allows large volumes of data to be reliably stored and accessed by multiple clients 24 hours a day, 365 days a year.

Integrated RV sensors

Regular hard disk drives without RV sensors can affect the performance of a multi-bay NAS System by generating 'knock-on' vibration. N300 drives ensure high reliability by minimising vibration effects through their advanced control and sensing technology. Multiple sensors detect the slightest shock and built-in RV sensors also compensate for rotational vibration - eliminating the possibility of 'knock-on' vibration in multi-bay NAS configuration systems.

Reliable always-on operation

NAS systems in small businesses or creative environments often need to be accessed by several users, at different locations, simultaneously. Therefore today's NAS drives must deliver high data transfer rates and simultaneous upload and download 24 hours a day, 7 days a week. Offering high reliability and scalability, N300 drives achieve a max. 180 TB/year workload factor, up to 3 times more than convenient desktop hard drives.

High durability and heat prevention

Use of high-endurance components is one of the reasons that the N300 series offers better durability than other conventional hard disk drives. At the same time, automatic adjustment of seek speed to reduce heat during high-temperature operation further improves endurance in demanding situations.

High speed for multi-drive environment

High performance and fast read speed is made possible under high data access loads from multiple users thanks to 256 or 128 MB data buffer. This makes the drive suitable for small businesses and creative professionals looking for solutions to handle high data volumes using multi-RAID NAS environments.

Optimised cache allocation

Toshiba’s Dynamic Cache Technology, a self-contained cache algorithm with on-board buffer management, optimizes how the cache is allocated during read/write to provide the high-level performance demanded by real-time domains.

Reduced noise and energy costs

The 12 TB and 14 TB N300 NAS Hard Drives use a helium-sealed design, achieving low power consumption while increasing storage density. Toshiba Group’s laser welding technology ensures that the helium remains securely sealed inside the drive enclosure. With the environment in mind, the helium-filled N300 models minimize acoustic output to just 20db (typical) in idle mode. The devices are ideal for large scale server systems allowing for rich scalability of up to 8 drives.

BUILT TO DELIVER, DESIGNED TO LAST

Toshiba is renowned the world over for 50 years of leading innovation – and the power behind its range of hard drives is no exception. Designed for high capacity and excellent performance, you can be sure that Toshiba’s wealth of experience in hard drives is at work in your storage system. A three year extended warranty is also included with the N300 for the ultimate peace of mind.
