Toshiba N300 14TB NAS Hard Drive (TON300NHD14T) – SATA 6Gb/s, 7200 RPM, 256MB Cache, CMR

The Toshiba N300 14TB (TON300NHD14T) is a 3.5-inch CMR hard drive for home and small-office NAS with up to 8 bays. With 7200 RPM operation, a 256MB cache and SATA 6Gb/s connectivity, it gives NAS owners dependable capacity for always-on workloads.

Dependable NAS capacity with Toshiba engineering.

Why Nas Workloads Need the Right Drive

NAS systems run 24/7 with several drives sharing heat and vibration; desktop and SMR drives can slow rebuilds and fail early in that environment.

The Toshiba N300 14TB is engineered for this role with CMR recording, rotational vibration sensors and firmware tuned for NAS duty (workload rating: 180TB per year). At 14TB per drive, it cuts the number of bays needed for the same usable capacity, which lowers power draw and simplifies NAS expansion.

Performance Where It Counts

A 7200 RPM spindle and 256MB cache deliver sustained throughput for large file transfers and shared access. The SATA 6Gb/s interface is backward compatible with SATA 3Gb/s ports and works with standard SATA controllers, NAS bays and server backplanes.

Reliability for Continuous Operation

Toshiba’s rotational vibration sensors and firmware tuning keep the drive stable in multi-bay enclosures running around the clock.

Setup Instructions

How to Install the Toshiba N300 14TB

1. Check your system supports 3.5-inch SATA drives at this capacity and power it down unless hot-swap is supported.
2. Mount the drive in a free bay or tray.
3. Connect or insert the drive and confirm detection in the BIOS, NAS software or recorder.
4. Initialise the drive, add it to a pool or RAID if needed, and enable health monitoring.
