Product overview of ST2400MM0129 Seagate 2.4TB

The ST2400MM0129 is a high-performance internal hard drive manufactured by Seagate. It is designed for use in enterprise-level servers, storage arrays, and other data-intensive applications that require high-capacity, high-speed storage.


The ST2400MM0129 has a storage capacity of 2.4 terabytes (TB), which is equivalent to 2,400 gigabytes (GB). This is a large amount of storage space and makes it suitable for storing large amounts of data, such as videos, photos, and documents.

The hard drive has a rotational speed of 10,000 revolutions per minute (RPM), which means it can access data quickly. The higher the RPM, the faster the hard drive can read and write data. This makes it suitable for applications that require fast access to data, such as databases and virtual machines.

Capacity and Performance

The Seagate ST2400MM0129 is a storage workhorse with a generous capacity of 2.4 Terabytes (TB). This ample storage space makes it an ideal choice for environments that require significant data storage capabilities. It can accommodate vast amounts of data, from business-critical information to multimedia content.

One of the standout features of this HDD is its fast rotational speed of 10,000 Revolutions Per Minute (RPM). Higher RPM results in faster data access times, making it suitable for applications that demand quick data retrieval. This speed is particularly advantageous for servers, workstations, and other enterprise environments where performance is paramount.

Interface Technology

The Seagate ST2400MM0129 utilizes the Serial-Attached SCSI (SAS) interface. SAS is a proven technology widely used in enterprise-grade storage solutions. The 12 Gigabits Per Second (GBPS) SAS interface employed in this HDD ensures a high-speed data transfer rate, making it well-suited for demanding applications that require rapid data access and retrieval.

SAS technology also provides robust error-checking and error-correction capabilities, enhancing data integrity and reliability. This is crucial in enterprise settings where data loss or corruption can have serious consequences.

Buffer Size

The Seagate ST2400MM0129 features an impressive 256 Megabytes (MB) buffer. The buffer, also known as cache, plays a crucial role in enhancing the overall performance of the HDD. When data is read or written, it is temporarily stored in the buffer, allowing for faster data transfer to and from the disk.

A larger buffer size can significantly reduce data latency, making data access operations more efficient. This is particularly valuable for applications that involve frequent data access, such as database management, virtualization, and high-transaction environments.

Form Factor

The Seagate ST2400MM0129 is designed in a 2.5-inch form factor. This compact size is a notable advantage, as it allows the drive to fit into a variety of systems and enclosures, even those with limited physical space. The 2.5-inch form factor is commonly found in laptops and enterprise-grade servers, making the Seagate ST2400MM0129 a versatile storage solution for both portable and rack-mounted systems.

Sector Size

This HDD employs the 512e sector technology. In traditional hard drives, the sector size is 512 bytes. However, with 512e, the drive emulates a 512-byte sector size while using a larger physical sector size. This technology is important for compatibility with legacy systems that expect a 512-byte sector size. It ensures that the Seagate ST2400MM0129 can seamlessly replace older drives without any compatibility issues.

Interface and Compatibility

The ST2400MM0129 hard drive uses the Serial Attached SCSI (SAS) interface, which is a high-speed interface used for connecting hard drives and other storage devices to servers and other computing systems. It has a maximum data transfer rate of 12 gigabits per second (Gbps), which is twice as fast as the previous generation SAS interface.

The hard drive is also compatible with the SAS-3 interface, which is the latest version of the SAS interface. SAS-3 offers even higher data transfer rates of up to 24 Gbps, which makes it suitable for even more data-intensive applications.

Form Factor and Reliability

The ST2400MM0129 hard drive has a 2.5-inch form factor, which is the standard size for enterprise-level hard drives. This makes it easy to install in servers and other computing systems that use this form factor.

The hard drive is also designed for reliability. It has a Mean Time Between Failures (MTBF) rating of 2 million hours, which means that it is expected to last for a long time before it fails. It also has a Non-Recoverable Error Rate (NRE) of less than 1 in 10^15 bits read, which means that it is very unlikely to lose data due to errors.

Cache and Power Consumption
  • The ST2400MM0129 hard drive has a cache size of 256 megabytes (MB). The cache is a small amount of high-speed memory that is used to store frequently accessed data. This can help to improve performance by reducing the time it takes to access frequently used data.
  • The hard drive also has a low power consumption of only 5.5 watts when it is operating. This can help to reduce the overall power consumption of a server or other computing system that uses the hard drive, which can save money on electricity bills.
  • In summary, the ST2400MM0129 is a high-performance internal hard drive that is designed for use in enterprise-level servers and other data-intensive applications. It has a large storage capacity of 2.4 TB and a high rotational speed of 10,000 RPM, which makes it suitable for applications that require fast access to data.
  • The hard drive uses the SAS interface and is compatible with both SAS-12Gbps and SAS-3 interfaces. It has a 2.5-inch form factor, is designed for reliability, and has a low power consumption. Overall, the ST2400MM0129 is a reliable and high-performance hard drive that is ideal for enterprise-level applications.
