Toshiba MG11ACA14TE Enterprise Capacity HDD 14TB 3.5 inch SATA 7200rpm 512MB CMR

The Toshiba MG11ACA14TE is a 14TB enterprise-class 3.5-inch hard disk drive from the Toshiba MG Series, engineered for demanding 24/7 data centre, cloud storage, and server workloads. Built with helium-sealed technology, CMR (Conventional Magnetic Recording) with 9 platters and 18 heads, and a 512MB cache buffer, this drive delivers sustained transfer rates of up to 260 MiB/s over the SATA 6Gb/s interface, making it one of the highest-capacity SATA enterprise HDDs in its class.

Advantages

The MG11ACA14TE is rated for an impressive 550TB/year workload, backed by a 2.5-million-hour MTBF rating and a non-recoverable read error rate of 1 per 10^15 bits, ensuring exceptional reliability for mission-critical storage applications. The helium fill reduces internal turbulence and power consumption, achieving an operating power draw of just 8.0W while maintaining 7200 RPM spindle speed for consistent high throughput. Advanced features including Native Command Queuing (NCQ), rotational vibration compensation, and 512e sector emulation make it compatible with modern storage platforms and RAID configurations.

Suitable for

• Data centre operators requiring high-capacity, reliable bulk storage at scale
• Cloud service providers and large enterprise NAS/SAN deployments
• Server administrators building high-density RAID arrays for backup, archiving, or primary storage
