This hard drive is designed for use in desktop PCs and workstations and offers solid performance for general storage needs. Below you will find a detailed description of the technical details, features, and application areas of this hard drive.
Technical Details
1. Capacity:
- 320 Gigabytes (GB). The ST3320820A offers a storage capacity of 320 GB, which is sufficient for many applications, including operating systems, applications and personal data.
2. Form Factor:
- 3.5 inches. The 3.5 inch form factor is the standard for desktop hard drives. This size is common for most desktop PCs and external hard drive bays.
3. Interface:
- SATA I (SATA 1.5 Gb/s). The hard drive uses a SATA I interface which enables data transfer rates of up to 1.5 Gb/s (150 MB/s). This is the first generation of SATA interfaces and offers slightly lower performance compared to later versions such as SATA II and SATA III.
4. Rotational Speed:
- 7,200 RPM (revolutions per minute). The ST3320820A spins at 7,200 RPM, which offers good performance for desktop hard drives. This rotational speed ensures fast access times and acceptable data transfer rates.
5. Cache Memory:
- 8 MB. The 8 MB cache memory helps improve the performance of the hard drive by caching frequently used data and retrieving it quickly.
6. Storage Type:
- Perpendicular Recording. This technology is used to increase the data density on the hard drive by writing the data perpendicular to the platter surface, improving storage capacity and performance.
7. MTBF (Mean Time Between Failures):
- 1 million hours (approximately). This number indicates how long the hard drive will operate on average between failures, indicating high reliability.
8. Operating and Environmental Conditions:
- Operating Temperature: Typically 0 to 60°C.
- Storage Temperature: Typically -40 to 70°C. These temperature conditions ensure reliable function under normal operating conditions.
9. Power Consumption:
- Operating Input: Typically 6 to 8 watts.
- Idle: Typically 4 to 5 watts. Power consumption is within the typical range for hard drives of this size and speed.
10. Noise Level:
- Typically up to 2.8 sone. This is the level of noise the hard drive makes during operation, which is relatively quiet for a hard drive of this type.
Features
