Seagate combines its most advanced HAMR hard drives in two new storage servers, the Exos 4U100 and the Exos 4U75. The maximum capacity of a single enclosure is a substantial 3.2 petabytes.
Seagate introduces two new proprietary storage servers: the Seagate Exos 4U100 & 4U74 JBOD. The devices are built to take advantage of the manufacturer’s large HAMR drives. The new drives, built on the proprietary Mozaic 3+ technology, contain 30 TB (and more in the future) in a single 3.5-inch HDD. Fill the new servers, and you get up to 3.2 PB of storage capacity in one enclosure.
Real-time Applications
The servers must balance energy efficiency, density, and throughput capacity in a device suitable for environments where data is heavily used. Seagate points to support for AI and ML workloads, among other things, due to the capacity to continuously ingest incoming data. The storage servers are therefore suitable for real-time applications such as analytics. Note: the Exos 4U100 and 4U75 are not flash-based, so they are not intended for the most high-performance storage.
The new servers support SAS or SATA and, according to Seagate, use 30 percent less power than their predecessors. They are designed for use by large enterprises with Secure Boot and Redfish management. With the servers, Seagate flexes its muscles: as an HDD specialist, the manufacturer now provides its own solution with modern HAMR drives, allowing users to combine very high storage density with energy efficiency.

The servers fit into racks of various depths and, as the name already suggests, have a 4U format. Seagate expects the devices to be available from the first quarter of 2026.
