Seagate Exos M 28TB SATA 7200RPM 3.5" Enterprise HDD

The Seagate Exos M 28TB (ST28000NM000F) is a 3.5-inch enterprise hard disk drive built on Seagate's Mozaic 3+ platform, leveraging Heat-Assisted Magnetic Recording (HAMR) technology to achieve 28TB of native capacity on a single spindle. HAMR uses a near-field laser integrated into the recording head to momentarily heat a small area of the disk platter to reduce magnetic coercivity, enabling data to be written to significantly denser magnetic grains than conventional PMR or SMR technologies allow. This architecture delivers a substantial areal density leap while maintaining the sequential read/write performance profile enterprises require for large-scale data workloads.

Running at 7200 RPM with a 512MB cache buffer and a SATA 6Gb/s interface, the Exos M 28TB is engineered for high-duty-cycle operation in dense storage enclosures. The drive is rated for a 550TB/year workload, reflecting its design intent for continuous, high-throughput environments. Seagate's PowerChoice and PowerBalance technologies are incorporated to give system operators granular control over power states, an important consideration when deploying hundreds or thousands of drives in a hyperscale rack. The drive also includes Seagate Secure instant secure erase capability for end-of-life data sanitization compliance.

The Exos M 28TB is attracting strong interest from hyperscale cloud operators and large enterprise storage builders seeking to maximize raw petabyte capacity per rack unit without transitioning to alternative form factors or interfaces. Its conventional 3.5-inch, SATA footprint ensures compatibility with existing JBOD enclosures, storage servers, and SAS/SATA backplane infrastructure, making it a practical high-capacity upgrade path. As the highest-capacity drive in the Exos M lineup at launch, it positions operators to reduce drive count, lower per-terabyte power draw, and simplify storage scaling across object storage, cold archive, and bulk data lake tiers.

Ideal for

• Hyperscale and cloud object storage buildouts requiring maximum raw capacity per drive bay to minimize rack footprint
• Cold and warm archive storage tiers in enterprise data lakes where sequential throughput and high capacity-per-spindle economics are critical
• Bulk media repositories for video surveillance, genomics, or seismic data that generate large volumes of write-once, read-many workloads
• NAS and scale-out file system deployments (e.g., Ceph, GPFS, Lustre) where per-node capacity expansion reduces cluster node count
• Backup target appliances and on-premises secondary storage where high sequential write throughput supports large backup windows
• Enterprise data center refresh cycles replacing aging, lower-capacity SATA drives to consolidate storage into fewer drives while maintaining existing SATA backplane infrastructure
