About the Seagate Exos X28 28TB SATA Enterprise Hard Drive
At 28 TB formatted capacity in a standard 3.5-inch form factor, the Seagate Exos X28 (part number ST28000NM000A) delivers dense, high-volume storage for enterprise data centers operating at scale. Built on Conventional Magnetic Recording (CMR) technology with an areal density of up to 2222 Gb/in², this SATA 6 Gb/s drive represents the upper tier of capacity-per-bay deployment for storage architects evaluating next-generation archive and warm-tier infrastructure.
Engineered for intensive 24/7 operation, the Exos X28 spins at 7200 RPM with a sustained transfer rate reaching up to 285 MB/s and a 256 MB cache buffer to smooth workload variability. Seagate rates the drive for an annualized workload of 550 TB/year and an MTBF of 2,500,000 hours, backed by rotational vibration compensation to mitigate mechanical stress in multi-drive enclosures. Power efficiency remains competitive, consuming 9.2 W during read/write operations and 5.4 W at idle, across an operating temperature range of 5°C to 60°C. The drive supports both 512e and 4Kn sector configurations and is available as a non-SED variant (no encryption). Seagate manufactures the Exos X28 to specification ST28000NM000A for validated integration into certified third-party storage systems.
Enterprise Deployment Scenarios
- High-capacity NAS and SAN arrays requiring maximum TB per drive bay in legacy SATA infrastructure
- Warm data archival tiers handling sequential read workloads and long-duration retention cycles
- Cloud service provider object storage backends optimized for cost-per-petabyte economics
- Large-scale backup appliances consolidating multiple 28 TB drives to reduce operational footprint
- Surveillance and media asset repositories where capacity density outweighs random-access latency requirements
