Toshiba N300 Pro 18TB NAS Hard Drive (HDWG81JXZSTB) – SATA 6Gb/s, 7200 RPM, 1GB Cache, CMR

The Toshiba N300 Pro 18TB (HDWG81JXZSTB) is a 3.5-inch CMR hard drive for business NAS with up to 24 bays. With 7200 RPM operation, a 1GB cache and SATA 6Gb/s connectivity, it gives NAS owners dependable capacity for always-on workloads.

18TB of CMR storage tuned for business NAS workloads.

Why Business nas Workloads Need the Right Drive

Business NAS arrays face heavier multi-user traffic and vibration than home systems, so drives need higher workload ratings and vibration protection.

The Toshiba N300 Pro 18TB is engineered for this role with CMR recording, rotational vibration sensors and firmware tuned for business NAS duty (workload rating: 300TB per year). At 18TB per drive, it cuts the number of bays needed for the same usable capacity, which lowers power draw and simplifies business NAS expansion.

Performance Where It Counts

A 7200 RPM spindle and 1GB 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.
