This hard drive boasts an impressive set of features, including a spacious 2 Terabytes (TB) storage capacity, a rapid 7200 Revolutions Per Minute (RPM) rotation speed, and Serial-Attached SCSI (SAS) connectivity at 6 Gigabits Per Second (6GBPS). With a generous 128 Megabytes (MB) buffer, this 3.5-inch hard drive is tailored to meet the demanding needs of servers, providing optimal performance and data integrity. In this description, we will delve into the key specifications, benefits, and potential applications of the Seagate ST2000NM0023 Constellation ES.3, shedding light on why it's a standout choice for server storage.

Key SpecificationsStorage Capacity 2 Terabyte

The Seagate Constellation ES.3 Internal Hard Drive offers a substantial 2 Terabytes of storage space, making it ideal for environments where large volumes of data need to be stored and accessed efficiently. This ample capacity ensures that the hard drive can accommodate extensive databases, applications, and multimedia files without the need for frequent upgrades.

Rotation Speed 7200 Revolutions Per Minute

The 7200 RPM rotation speed of the Seagate ST2000NM0023 plays a crucial role in enhancing data access speed. This faster rotation enables quicker read and write operations, reducing latency and improving overall system responsiveness. This makes the hard drive well-suited for applications that demand rapid data retrieval, such as database management and file hosting.

Interface Serial-Attached SCSI (SAS) at 6 Gigabits Per Second

The Serial-Attached SCSI (SAS) interface is a distinguishing feature of the Constellation ES.3 hard drive. SAS provides a high-speed, point-to-point connection that facilitates reliable data transfer at 6 Gigabits Per Second (6GBPS). This ensures a robust and efficient link between the hard drive and the server, contributing to seamless data flow and reduced bottlenecks in data-intensive tasks.

Buffer Size 128 Megabytes

The presence of a substantial 128-megabyte buffer enhances the hard drive's performance by temporarily storing frequently accessed data. This buffer acts as a temporary holding area for data being transferred to or from the drive, minimizing delays and optimizing overall data throughput. The sizable buffer is particularly advantageous in scenarios where rapid and consistent access to data is paramount.

Form Factor 3.5 Inches

The 3.5-inch form factor of the Seagate Constellation ES.3 makes it compatible with standard server configurations. This form factor is a common industry standard, ensuring that the hard drive can be seamlessly integrated into a variety of server setups without the need for additional adapters or modifications.
