Error recovery control
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.
High-Reliability NAS Hard Drive
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
Temperature control technology, through the automatic adjustment of rotational speed, prevents the build up of heat during demanding operations resulting in sustained drive performance and long-term reliability. Also, the use of high-endurance components is one of the reasons that the N300 Series offers better durability than other conventional hard disk drives.
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 a 256 MB / 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.
Optimized 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.
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.

Where to buy
Toshiba created a great NAS drive with their N300 series. It is a drive that comes with the right features and a great performance to match.
For the combination of characteristics, prices
and quality, the editors unequivocally award the TOSHIBA N300 4TB hard drive with the 'Editor's Choice' award.
The N300 hard drive fits seamlessly into Toshiba's already existing hard disk product portfolio and in our opinion complements it in a way that makes a lot of sense.
The N300 is suitable for continuous operation, especially for small and medium sized NAS devices up to 8 hard disks. At the time of testing, the Toshiba N300 4TB (HDWQ140EZSTA) price-performance ratio is at a top level.
Both in the synthetic benchmarks and in
PCMark, the Toshiba N300 is one of the fastest 4 TB drives we've tested so far. The throughput speeds are around the promised 200 MB/s.
It’s a fast performing drive packed with features to help it survive in a multi-disk environment.
