Product overview

Toshiba’s N300 14TB NAS HDD joined the N300 family on December 5, 2018, when Toshiba added 12TB/14TB helium‑sealed models to the line. It’s a 3.5‑inch SATA (6 Gb/s) CMR drive rated for 24/7 use with a 7200 RPM spindle, 512 MB cache, RV sensors, and a 180 TB/year workload rating.

Positioned as a mainstream NAS hard drive, it exists to deliver dependable, high‑capacity bulk storage for home and SOHO multi‑bay enclosures. It’s well‑suited to mass storage and housing large game libraries where sequential throughput matters more than latency. Not discontinued; the 14TB capacity remains in Toshiba’s current N300 lineup. Unique note: the 12TB/14TB capacities use a helium‑sealed design for lower turbulence and higher platter count.
