Built for enterprise NAS arrays

This 16 TB Toshiba N300 Pro drive uses CMR recording at 7200 RPM with a 512 MB cache and a SATA 6.0 Gb/s interface. It is designed for multi-bay NAS enclosures that demand sustained write performance and vibration tolerance in 3.5-inch bays. The five-year manufacturer coverage reflects its enterprise-grade positioning.

Suits RAID-heavy NAS workloads.

Administrators who need consistent throughput for RAID rebuilds, backup targets or media streaming will benefit from the CMR design and large cache. Builders looking for a quiet desktop drive, a 2.5-inch form factor, or a non-enterprise warranty should consider other product lines.

The deciding spec is 16 TB CMR at 7200 RPM

That combination of capacity, conventional magnetic recording and spindle speed determines whether the drive fits your RAID stripe size, rebuild-time budget and throughput requirements. Verify that your NAS chassis accepts 3.5-inch SATA drives and that the controller supports the full 6.0 Gb/s link rate.
