Technical Details
1. Model Name: ST320LT020-9YG142
2. Manufacturer: Seagate
3. Capacity: 320 GB (Gigabytes)
4. Form Factor: 2.5 inches (standard size for laptop hard drives)
5. Interface: SATA II (3 Gb/s)
6. Rotational Speed: 5400 RPM (Revolutions Per Minute)
7. Cache Memory: 8 MB
8. Interface Speed: 3 Gb/s (SATA II)
Features
1. Performance:
- 5400 RPM: This rotational speed is typical for laptop hard drives and offers a balance between performance and energy efficiency. Compared to 7200 RPM hard drives, the performance is slightly lower, however the energy consumption is reduced, which extends the life of the laptop battery.
- 8 MB Cache: Cache memory improves performance by temporarily storing frequently accessed data, which reduces access times and increases the overall speed of the hard drive.
2. Interface:
- SATA II (3 Gb/s): Provides a reliable connection and transfer rates up to 3 Gb/s. Although this is slower than the newer SATA III interfaces, it is still sufficient for most applications.
3. Reliability:
- Error Correction: Built-in error correction and monitoring technologies help ensure data integrity and prevent data errors.
4. Energy Efficiency:
- Low Power Consumption: The 5400 RPM rotation speed and efficient use of power make the hard drive suitable for use in mobile devices such as laptops where energy efficiency is critical.
5. Noise Level:
- Quiet Operation: Designed for quiet operation, making it ideal for noise-sensitive environments, such as working in a quiet office or bedroom.
Application range
1. Laptops:
- Primary storage: Ideal for laptops as a primary hard drive. The compact size and low power consumption make it perfect for mobile devices.
2. Desktop PCs:
- Secondary drive: Can be used in desktop PCs as an additional drive for storing data, backups or less speed-critical applications.
3. External enclosure:
- External drive: Can be used in an external hard drive enclosure to provide an additional and portable storage solution.
4. Backup Solutions:
- Data Backup: Good choice for backup purposes as the 320GB capacity provides ample space for personal data and important files.
5. Upgrade from Older Systems:
- Replacement of Old Hard Drives: Useful for upgrading older systems with limited storage space to provide more capacity.
Physical Specifications
1. Dimensions:
- Form Factor: 2.5 inches (69.85mm x 100.2mm x 9.5mm), suitable for laptops and compact desktop cases.
2. Weight:
- Around 90-120g, making them lightweight and portable, ideal for portable devices.
3. Case Material:
- Durable metal or plastic that provides protection and helps in heat dissipation.
Additional Details
- Compatibility:
- SATA II: The hard drive is backwards compatible with older SATA I interfaces and can operate in newer SATA III ports, but only at SATA II speeds.
- Temperature Range:
- Operating Temperature: Typically from 0°C to 60°C
- Storage Temperature: From -40°C to 70°C
- Warranty:
- Typically 2 to 3 year limited warranty, depending on manufacturer's terms.
