2. Capacity: 200 GB
3. Form Factor: 2.5 inch
4. Interface: SATA 3 Gb/s (SATA II)
5. Rotational Speed: 5400 RPM (Revolutions Per Minute)
6. Cache: 8 MB
7. Average Access Time: About 12 ms (milliseconds)
8. Maximum Transfer Rate: Up to 300 MB/s (Megabytes per second)
9. MTBF (Mean Time Between Failures): Typically 600,000 hours
10. Operating Temperature Range: 5°C to 60°C
11. Shock Resistance: Up to 1000 G at 1 ms

Features:


1. Capacity: The ST9200420ASG offers 200GB storage capacity, which provides enough space for a wide range of applications such as operating systems, applications and personal data.

2. 2.5-inch form factor: The 2.5-inch form factor makes this hard drive ideal for laptops and compact desktop PCs as it is smaller than 3.5-inch hard drives and thus takes up less space.

3. SATA II Interface: The SATA II (SATA 3 Gb/s) interface enables a maximum data transfer rate of up to 300 MB/s. This interface is backwards compatible with SATA I (1.5 Gb/s) and offers solid performance for everyday applications.

4. 5400 RPM Rotational Speed: The hard drive spins at 5400 RPM, making it an energy efficient choice. While 5400 RPM drives are typically not as fast as 7200 RPM drives, they offer a good balance between performance and energy consumption.

5. 8 MB Cache: The 8 MB cache improves performance by temporarily storing frequently accessed data and speeding up access to that data.

6. Shock and Vibration Protection: Designed for use in portable devices, the hard drive offers protection against shock and vibration. This contributes to data integrity and reliability, especially in mobile environments.

7. Energy Management: The hard drive is energy efficient and helps minimize power consumption in laptops and other devices. This can contribute to longer battery life in portable devices.

8. Performance Optimization: The hard drive uses performance optimization technologies to ensure consistent performance and extend the life of the hard drive.

Application Range:


1. Laptops and Notebooks: The ST9200420ASG is ideal for laptops and notebooks because its 2.5-inch form factor fits it in these devices and its power efficiency and shock resistance match the needs of portable devices.

2. Desktop PCs: In desktop PCs, this hard drive can be used as a secondary drive to provide additional storage space or act as a backup drive.

3. System Upgrades: The ST9200420ASG can be used to upgrade older laptops and desktop PCs to provide additional storage space and improve performance, especially when replacing an old, smaller or slower hard drive.

4. Storage Expansion: For systems that require additional storage capacity, this hard drive can be used as an additional drive to store files, media and other data.

5. Compact Applications: Due to its compact size, this hard drive is also suitable for devices where space is limited, such as in compact PC cases or external hard drive racks.

6. Backup Solutions: The ST9200420ASG can also be used as a backup drive to back up important data and ensure data security.

Conclusion:


The ST9200420ASG from Seagate is a reliable 2.5-inch hard drive with a capacity of 200 GB and a SATA II interface. It offers balanced performance with a rotation speed of 5400 RPM, an 8 MB cache and solid shock and vibration protection. This hard drive is particularly well suited for use in laptops and portable devices, but also offers a useful extension for desktop PCs and as a backup drive. Its energy efficiency and protection measures against physical damage make it a robust and reliable choice for a wide range of storage needs.
