Toshiba 20TB Enterprise 3.5 Inch Hard Drive – 20TB 3.5-inch enterprise SATA hard drive with 7200 RPM, 1024 MB (1 GB) cache, SATA 6 Gb/s interface, helium-sealed FC‑MAMR design, CMR recording, 550 TB/year workload rating, ~268 MB/s sustained transfer rate, 2.5M hours MTTF, built for cloud-scale servers, storage arrays, and data centers.
Product Overview
The Toshiba HDEB038GEA51F is a 20TB enterprise-class 3.5″ HDD from the MG11 series, designed for high-density, always-on storage in servers, SAN/NAS arrays, and cloud infrastructure. It uses Toshiba’s helium-sealed, 10-disk platform with Flux Control Microwave Assisted Magnetic Recording (FC‑MAMR) to achieve 20TB capacity in a standard 3.5″ form factor while maintaining Conventional Magnetic Recording (CMR) compatibility for broad OS and RAID support. Performance is rated at 7200 RPM with a large 1024 MB (1 GB) cache and SATA 6 Gb/s interface, delivering sustained sequential transfers around 268 MB/s. Reliability features include a 550 TB/year workload rating, 2.5 million hours MTTF, advanced vibration tolerance, and Persistent Write Cache technology to protect against data loss during sudden power events. Power efficiency is optimized for rack-scale deployments, and the drive is RoHS and halogen-free compliant. Toshiba typically backs enterprise MG-series drives with a 5-year limited warranty.
