14 TB NAS Drive for Multi-Bay Enclosures

The Toshiba N300 HDWG51EXZSTA is a 14 TB internal hard drive built for network attached storage. It uses a SATA 6.0 Gb/s interface and spins at 7200 rpm with a 512 MB buffer. The 3.5 inch form factor fits standard NAS bays and is engineered for 24/7 operation in personal, home office, or small business environments.

Sustained Performance with Vibration Compensation

Rotational vibration sensors detect and correct transient vibrations automatically, keeping throughput steady when multiple drives run side by side. The design supports up to eight drive bays in a multi-RAID layout and is rated for a workload rate of up to 180 TB per year. This makes it suitable for continuous workloads such as multimedia servers, private cloud storage, and small business servers.

Upgrade from Lower-Capacity or Desktop Drives

The jump is worthwhile when a NAS needs more raw capacity than smaller drives provide or when a desktop-class drive cannot handle the vibration and duty cycle of a multi-bay array. It replaces drives that lack RV sensors or a comparable annual workload rating. Buyers who need a different interface or a non-NAS optimised drive should look elsewhere.

Questions about this item

How much power and heat does the 7200 rpm N300 generate during 24/7 NAS operation?

The drive is engineered for continuous 24/7 use with a workload rating of up to 180 TB per year, and its rotational vibration sensors help maintain stable performance in multi-bay enclosures.

What host interface and bay size does the 3.5" SATA 6.0Gb/s drive require?

It needs a standard 3.5-inch drive bay and a SATA 6.0Gb/s port on the motherboard or RAID controller, plus a SATA power connector from the power supply.

Will the 512 MB buffer N300 work reliably in an older 4-bay NAS that only supports SATA 3Gb/s?

Yes, the SATA 6.0Gb/s interface is backward compatible with 3Gb/s ports, and the RV sensors compensate for vibration in enclosures with up to 8 drive bays.
