Enterprise-Grade Cloud-Scale Storage
The Toshiba MG10 Series MG10ACA20TE delivers 20TB of Conventional Magnetic Recording (CMR) capacity using Toshiba's innovative Flux Control Microwave Assisted Magnetic Recording (FC-MAMR) technology. Featuring a fourth-generation, 10-disk helium-sealed design, this drive achieves 2TB per disk density while maintaining exceptional reliability. The industry-standard 3.5-inch form factor with 7200 RPM performance integrates seamlessly into cloud-scale storage infrastructure, business-critical servers, and file/object storage solutions.
Reliability and Performance
With a 512MB cache buffer and SATA 6.0 Gbit/s interface, the MG10ACA20TE delivers maximum sustained data transfer speeds of 268 MiB/s. The drive includes Toshiba Persistent Write Cache Technology for data-loss protection during sudden power-loss events (512e models). Rated for 24/7 continuous operation with a 550 TB/year workload capacity and 2,500,000-hour MTTF, this enterprise-class drive provides unsurpassed data reliability and application compatibility.
Optimized Total Cost of Ownership
The helium-sealed mechanics reduce aerodynamic drag, delivering a lower operational power profile (9.3W typical) and excellent power efficiency (W/TB) for superior TCO. The drive supports both 512e and 4Kn Advanced Format Sector Technology options, providing flexibility for diverse storage environments.
