MG09ACA14TA Toshiba MG Cloud Scale Capacity 14TB SATA 512 MB 3.5" Server HDD

High-Density 3.5in Nearline SATA Enterprise HDD featuring CMR and 4Kn alignment with the MG09ACA14TA

The MG09ACA14TA is a 14TB 3.5in internal SATA enterprise HDD engineered for nearline bulk storage in rack servers and high-density JBOD enclosures where predictable latency and consistent write behavior are required. In modern x86 storage nodes and backup appliances, the MG09ACA14TA complements CPU- and memory-heavy controller architectures by delivering capacity-oriented performance while keeping host resources focused on deduplication, encryption, and metadata services.

Designed for storage backplanes and HBA/RAID controllers on PCIe-based platforms, the MG09ACA14TA supports CMR media and 4Kn sector format to reduce read-modify-write overhead and improve RAID rebuild efficiency versus mixed sector environments. A 512MB cache with Persistent Write Cache (PWC) improves data integrity during power-loss events in write-heavy ingest windows, while a helium-filled 7200 RPM design targets stable thermals and vibration-sensitive multi-drive arrays operating under a 24/7 duty cycle.

Why Choose the MG09ACA14TA?

The MG09ACA14TA is optimized for dense capacity per RU, enabling scalable growth of archive tiers, object repositories, and warm/cold data lakes without shifting to higher-cost flash. With enterprise reliability targets and 2.5M hours MTTF, the MG09ACA14TA fits RAID deployments that prioritize consistent media characteristics, operational continuity, and predictable fleet behavior across large drive counts.

Toshiba designs the MG series around datacenter qualification, focusing on long-life components, firmware tuned for multi-drive environments, and compatibility with standard SATA storage infrastructures used in modern data centre architectures.

Key Applications:

• Backup and archive repositories
• Object storage nodes
• Cold and warm data lake tiers
• Nearline bulk capacity in JBOD
• RAID storage expansion shelves
