Seagate Exos X24 20TB 512E/4KN Standard SAS

The Seagate Exos X24 20TB hard drive serves as high-capacity storage for servers, data centres and enterprise systems. The manufacturer designed it for continuous operation in high data density environments, such as cloud platforms and massive scale-out architectures. This 3.5" internal drive uses a SAS interface and reaches speeds of 7200rpm. For rapid processing of data operations, the 20TB SAS hard drive is equipped with a 512MB cache, which supports sequential transfer speeds of up to 285MB/s. The CMR recording technology delivers consistent performance even during demanding random write operations.

Key features of the Seagate Exos X24 20TB 512E/4KN standard SAS hard drive

  • SAS interface supports high transfer speeds
  • Helium-filled design reduces operating power consumption and vibration
  • PowerBalance technology optimises the power-to-capacity ratio (W/TB)
  • Mean time between failures (MTBF) is rated at 2.5 million hours
  • Seagate Instant Secure Erase function for fast and secure data deletion
  • CMR recording technology delivers consistent random write performance
  • Serves high-density storage servers and data centres

Design and efficiency of the Seagate Exos X24 20TB hard drive

The drive uses a helium-filled design, which reduces friction and vibration inside the chassis. This approach leads to a lower operating temperature and weight. In addition, PowerBalance technology optimises power consumption per terabyte, contributing to more efficient operation in high-density data centres. Inside the drive, digital sensors monitor internal operating conditions and help maintain stable performance.

Performance and reliability

The drive achieves sequential read and write speeds of up to 285MB/s. Enhanced caching ensures a fast response in cloud and scale-out applications where reliable data access is a priority. The Seagate Exos SAS is designed for continuous operation and has a mean time between failures (MTBF) of 2.5 million hours. Its high reliability makes it suitable for operation in critical enterprise applications.

Data management and security on the Seagate Exos X24 20TB drive

For easy drive decommissioning, it integrates the Seagate Instant Secure Erase feature. This provides fast and secure erasure of all data without the need for physical destruction. This 20TB server drive thus meets the requirements for secure data lifecycle management in an enterprise environment. The overall architecture allows for easy integration into rack-mounted storage and supports the building of petabyte-scale systems.
