The Seagate ST2400MM0129 is a 2.5 inch internal hybrid hard drive created for enterprise servers and storage systems that need both capacity and consistent performance. It provides 2.40 TB of space and augments that storage with 16 GB of flash memory, so frequently accessed data moves in and out of the drive faster than on a traditional mechanical disk.

A 12 Gb per second SAS interface keeps data flowing smoothly. Combined with a 10,000 rpm spindle, a 256 MB buffer, and onboard flash, the drive can reach up to 270 MB per second for internal transfers and as much as 1.2 GB per second across the interface. Average latency is measured at 2.9 ms, which helps workloads such as virtual machines, transactional databases, and real-time analytics respond without delay.

Seagate complements the raw performance with features that simplify management. Instant Secure Erase lets administrators retire or redeploy drives in minutes instead of hours. PowerChoice offers power tuning that reduces consumption during quiet periods. Support for both 512e and 4Kn formats eases migration from legacy systems to modern infrastructures, and Seagate RAID Rebuild accelerates array recovery after a drive swap.

The 2.5 inch form factor fits easily into dense server bays, blade enclosures, and space constrained storage shelves. An operating temperature window from 41 °F to 131 °F aligns with typical data center conditions, so the drive can be deployed in most enterprise environments without special cooling requirements. Whether you are expanding a high-transaction database, adding capacity to a virtual host, or building out a high-density SAN, the ST2400MM0129 delivers a practical mix of speed, capacity, and secure management.

Highlights:
  • 2.40 TB capacity supported by 16 GB of flash for quicker access to hot data
  • SAS interface at 12 Gb per second with up to 1.2 GB per second external transfer
  • 10,000 rpm spindle and 2.9 ms latency for responsive enterprise workloads
  • 256 MB buffer with support for advanced 512e and 4Kn sector formats
  • Instant Secure Erase, Seagate RAID Rebuild, and PowerChoice for efficient management
