MG11ACA20TE Toshiba MG Cloud Scale Capacity 20TB SATA 1 GB 3.5" Server HDD

High-Capacity 3.5in Enterprise SATA HDD architecture featuring CMR and FC-MAMR with the MG11ACA20TE

The MG11ACA20TE is a 20TB 3.5in internal enterprise HDD engineered for cloud-scale and nearline tiers where capacity, predictable latency, and serviceability matter more than peak IOPS. As a SATA 6Gb/s device running at 7200 RPM, the MG11ACA20TE aligns with standard server backplanes and JBOD shelves, enabling dense storage pools without requiring specialized controllers.

Built on CMR with FC-MAMR, the MG11ACA20TE sustains stable write behavior for rebuilds, scrubbing, and continuous ingest workloads typical in object and file storage nodes. Support for 4Kn with 512e emulation simplifies integration across mixed-OS fleets while optimizing format efficiency for modern filesystems. A ~1GB cache and Persistent Write Cache (PWC) strengthen write-path integrity during power events, and the helium-filled design improves thermals and acoustics in high-bay enclosures, supporting 24x7 duty cycles and predictable operational profiles.

Why Choose the MG11ACA20TE?

The MG11ACA20TE delivers a strong density-to-power ratio for scale-out architectures, allowing IT teams to increase usable capacity per rack while maintaining manageable thermal envelopes. With 2.5 million hours MTTF, the MG11ACA20TE is positioned for enterprise reliability in large drive-count environments, where consistent behavior during RAID rebuilds and data lifecycle operations directly impacts platform availability and operational risk.

Toshiba designs enterprise HDD platforms with a focus on sustained datacenter operation, firmware stability, and mechanical robustness for continuous duty. The MG11ACA series targets modern storage standards by supporting advanced sector formats, power-optimized operation, and data-protection features aligned with enterprise governance and resiliency requirements.

Key Applications:

• Nearline capacity tiers in rack servers and JBODs
• Backup repositories and archival storage
• Scale-out object storage nodes
• NAS file services and content libraries
• Data lake and cold analytics storage
