Seagate Exos X28 28TB SATA Enterprise HDD

The Seagate Exos X28 is a 3.5-inch enterprise hard disk drive leveraging Heat-Assisted Magnetic Recording (HAMR) technology to achieve a 28TB native capacity on a single spindle. HAMR uses a near-field laser integrated into the write head to momentarily heat a tiny area of the disk platter, enabling the use of higher-coercivity recording media that dramatically increases areal density without sacrificing data stability. This allows Seagate to push beyond the areal density ceiling of conventional Perpendicular Magnetic Recording (PMR) and even Shingled Magnetic Recording (SMR) technologies, delivering CMR-class random write performance at capacities that were previously unattainable on a single drive. The Exos X28 utilizes a multi-platter sealed helium-filled enclosure to reduce rotational drag, lower operating temperatures, and maintain a power-efficient profile consistent with high-density rack deployments.

Targeted at hyperscale data centers, enterprise object storage platforms, cloud storage backups, and large-scale archival repositories, the Exos X28 operates at 7200 RPM and interfaces via a 6Gb/s SATA III connection, making it broadly compatible with existing SATA-based JBOD enclosures, storage servers, and high-density disk shelves without requiring infrastructure reinvestment. The drive features a 512MB cache buffer that accelerates sequential read and write throughput, with sustained transfer rates suited for streaming large media files, backup datasets, and genomic or scientific data archives. Seagate's PowerBalance technology allows administrators to choose between maximizing performance or minimizing power consumption depending on workload profile.

The Exos X28 is rated for a 550TB per year workload, reflecting its enterprise-grade duty cycle and suitability for always-on, multi-drive array environments. It incorporates Seagate Secure instant secure erase capabilities for cryptographic data sanitization at end-of-life, along with advanced vibration compensation (RAVP) that uses dual accelerometers to counteract vibration in densely packed multi-drive enclosures. The drive's combination of HAMR-driven maximum capacity, proven enterprise reliability features, and SATA compatibility positions it as a cost-efficient density leader for petabyte-scale storage build-outs launching in late 2025.

Ideal for

• Hyperscale object storage clusters (e.g., S3-compatible platforms) requiring maximum TB-per-rack-unit density to reduce physical footprint and power draw per petabyte stored
• Cold and warm data archival vaults where infrequently accessed datasets such as compliance records, legal documents, and surveillance footage must be retained long-term at scale
• Enterprise backup and disaster recovery repositories where high-capacity single drives simplify target storage sizing and reduce the total number of drive bays required
• Media and entertainment content libraries storing high-resolution RAW video, rendered assets, and production masters that demand deep capacity per drive with reliable sequential throughput
• Genomics and life sciences research platforms that accumulate massive sequencing datasets requiring dense on-premises primary or secondary storage at petabyte scale
• Cloud service provider infrastructure refreshes replacing older, lower-capacity drives with maximum-density 28TB units to expand per-node storage capacity without adding new enclosures
