  • Seagate Exos 10E2400 ST300MM0048 300GB 2.5-Inch SFF 12Gbps 10K RPM 512n SAS Hard Drive
  • Seagate Exos 10E2400 ST300MM0048 300GB / 3000GB 2.5" Small Form Factor 12.0 Gb/s 10,000 RPM 512 Native Serial Attached SCSI / SAS Hard Drive / HDD 

Seagate Exos 10E2400 enterprise hard drives are the industry’s fastest 10K-RPM drives, with capacities up to 2.4TB in a 2.5-inch form factor, and intended for traditional data centers where density, power consumption and data integrity are paramount.

The Perfect Match of High Capacity and High Performance

The high capacity and small 2.5-inch footprint of the Exos 10E2400 drive enables data centers to keep pace with data growth and optimize data center real estate. Exos 10E2400 delivers up to 2.4TB of high-performance data access for write-intensive applications. A single advanced format interface model lets you future-proof your storage infrastructure. The Seagate Enhanced Caching feature accelerates read and write I/O operations, preventing applications from slowing down under peak usage conditions. The latest 12Gb/s SAS interface provides improved scalability.

Maximize Storage Investments for the Long Haul

Exos 10E2400 offers Protection Information (I) to help protect against data corruption, and Seagate PowerChoice technology for T10-compliant power management enables IT organizations to tailor systems for enhanced poser consumption. RAID recovery is faster and safer with the help of the Seagate RAID Rebuild technology option.

Industry-Leading Data Security Features

Seagate Secure SED and FIPS 140-2 government-grade models offer hardware-based security to help protect data-at-rest. With Instant Secure Erase, drive retirement is safe, fast and cost-effective. Seagate Secure models meet the NIST 800-88 media sanitization specification and support the Trusted Computer Group (TCG) standard.
