TECHNOLOGIES AND INNOVATIONS

• Protection Information (PI) — Adds mechanisms for checking data integrity along the path between the drive and the host system when supported by the controller and software.

• Seagate PowerChoice — Allows compatible systems to manage power consumption through supported power modes, helping optimize operating costs in data centers.

• Seagate RAID Rebuild — Supports the RAID array rebuilding process in compatible configurations and can reduce the time an array operates with reduced redundancy.

• Instant Secure Erase (ISE) — Designed for fast and secure data erasure when a compatible drive is decommissioned; availability depends on the specific model and configuration.

• Seagate FastFormat — Enables switching between 512e and 4Kn sector formats, making it easier to adapt the drive to different server infrastructure requirements.

• Intelligent NAND Endurance Management — Manages the use of embedded eMLC NAND memory to help maintain its endurance while accelerating input/output operations.

DESCRIPTION

In enterprise server environments, storage density, power consumption, and data access reliability must be managed simultaneously, particularly under continuous workloads. The Seagate Exos 10E2400 ST1200MM0129 combines a 1.2 TB capacity with a compact 2.5-inch SFF form factor and a rotational speed of 10,000 rpm. This combination enables high-density storage configurations without requiring the larger 3.5-inch form factor. The SAS interface, with a transfer rate of 12 Gb/s, is designed for enterprise controllers and infrastructures where scalability and predictable performance under load are important. The 256 MB cache and technologies designed to accelerate input/output operations support handling multiple requests, while actual performance depends on the configuration and workload characteristics. This model is suitable for server applications, virtualization, databases, transaction processing systems, and write-intensive workloads. It can also be used in SAS RAID arrays and enterprise storage systems, including SAN solutions, provided the controller and drive configuration are compatible. Support for 512e and 4Kn allows the sector format to be selected according to infrastructure requirements. If you need an enterprise 10K rpm drive for an existing SAS system, verify controller compatibility, form factor, and sector format before ordering.

SUITABLE FOR

• Enterprise servers with 2.5" SFF drive bays and SAS support.

• RAID arrays handling workloads with numerous read and write operations.

• SAN storage systems equipped with compatible SAS drive interfaces.

• Database and virtualization servers using 10K rpm drives.

• Upgrading or replacing existing SAS drives, provided capacity, sector format, and firmware requirements are compatible.

Compatibility note: A SAS controller or SAS backplane with a suitable 2.5" SFF drive bay is required. A SAS drive does not work with a SATA controller. Before installation, check support for 512e/4Kn, firmware requirements, and the limitations of the specific server or storage system.
