Toshiba N300 Pro 14TB NAS Hard Drive (HDWG51EAZSTB)

The Toshiba N300 Pro 14TB NAS Hard Drive (model HDWG51EAZSTB) is purpose-built for medium and large-sized businesses that demand always-on storage performance. Engineered for 24/7 continuous operation, it fits directly into NAS enclosures supporting up to 24 drive bays, making it a scalable choice for growing organisations that need high-density storage without frequent drive swaps. At its core, the N300 Pro spins at 7200 RPM — a speed tier that provides the responsiveness required for multi-user environments where concurrent read and write operations are constant. The drive uses Conventional Magnetic Recording (CMR) technology, which maintains write consistency and long-term data integrity under sustained, high-intensity workloads — an important consideration for NAS deployments where data is written continuously over months or years. The drive supports an annual workload rating of up to 550 TB per year, placing it well above standard desktop drives and squarely in the territory of enterprise-grade NAS storage. It connects via a SATA 6.0 Gbit/s interface, ensuring compatibility with virtually all modern NAS platforms and RAID controllers. Toshiba backs the N300 Pro with a 5-year warranty, reflecting the drive's design intent for long-duration deployment in business-critical environments. Whether configured in RAID 0, 1, 5, 6, or 10 arrays, the N300 Pro's CMR recording method ensures predictable and reliable rebuild performance — a practical advantage during array recovery events.
