MG10SCA20TE Toshiba MG10 Series 20TB SAS 512 MB 3.5" NAS HDD

High-Density 3.5" Enterprise SAS Nearline HDD featuring CMR helium design with the MG10SCA20TE

The MG10SCA20TE is a 20TB 3.5" internal enterprise HDD engineered for SAS-attached nearline tiers where storage density, predictable latency, and 24/7 duty cycles matter more than peak IOPS. In server and storage platforms with dual-socket CPU generations and large DRAM caches, the MG10SCA20TE complements memory-resident caching layers by delivering consistent sequential throughput and stable queue behavior for bulk data services.

Designed for modern backplanes and HBA/RAID controllers, the MG10SCA20TE integrates cleanly into PCIe-based storage stacks through SAS expanders, supporting scale-out enclosures and high-bay JBOD architectures. CMR recording with FC-MAMR and a helium-sealed mechanism improves areal efficiency while keeping power and thermals controlled, enabling higher drive counts per rack without compromising airflow planning. Advanced Format 512e supports alignment with contemporary filesystems and object storage layouts, reducing operational friction during migrations and mixed-sector estates.

Why Choose the MG10SCA20TE?

The MG10SCA20TE is optimized for dense capacity per RU, pairing enterprise reliability with a deployment profile suited to large drive pools and predictable rebuild behavior. With a 2.5M-hour MTBF/MTTF rating and a 7200RPM design, the MG10SCA20TE supports scalable nearline tiers where service continuity, capacity planning, and lifecycle consistency are critical in multi-shelf environments.

Toshiba’s MG10 engineering focuses on sustained operation in data centre conditions, using helium sealing and controlled mechanics to improve efficiency at scale. The MG10SCA20TE aligns with enterprise storage standards by prioritizing long-duty workloads, compatibility with SAS infrastructures, and dependable operation across 5–55°C operating ranges.
