This hard drive belongs to the WD Caviar Blue series and offers a storage capacity of 320 GB. Here is a detailed description of the technical details, features and application areas of the WDC WD3200AAJS-40H3A0 hard drive.
General Description
The WDC WD3200AAJS-40H3A0 is a 3.5-inch SATA hard drive used in desktop computers, external enclosures and other storage media. It belongs to the WD Caviar Blue series, which is known for general use and for a good compromise between performance, capacity and price.
Technical Details
1. Form Factor:
- 3.5 inches: The hard drive has the standard 3.5 inch form factor commonly used in desktop PCs and larger external enclosures.
2. Interface:
- SATA I (SATA 1.5 Gb/s): The hard drive uses the SATA I interface, also known as SATA 1.5 Gb/s. This interface supports a maximum theoretical transfer rate of 1.5 Gb/s (about 150 MB/s).
3. Capacity:
- 320 GB: The hard drive offers a storage capacity of 320 gigabytes, which provides enough space for the operating system, applications, and a large amount of data and files.
4. Rotational Speed:
- 7,200 rpm (RPM): The hard drive rotates at a speed of 7,200 revolutions per minute. This provides relatively fast access times and good data transfer performance compared to slower hard drive models.
5. Cache memory:
- 16 MB: The hard drive is equipped with a 16 MB cache that temporarily stores data and speeds up access to frequently used data. A larger cache can improve performance when there are many read and write operations.
6. Average access time:
- 8.9 ms: The average access time is around 8.9 milliseconds, which is a good response time for a hard drive of this class. The access time affects how quickly data can be found on the hard drive and read or written.
7. MTBF (Mean Time Between Failures):
- 1 million hours: The mean time before failure (MTBF) is typically 1 million hours, which indicates a high reliability and longevity of the hard drive.
8. Power consumption:
- Operating mode: Typical power consumption during operation is around 6-7 watts.
- Idle mode: In idle mode, power consumption is around 4-5 watts.
- Power supply: The hard drive is powered via the SATA power connector.
9. Construction:
- Case: The hard drive is housed in a robust casing that protects it from physical damage and helps with heat dissipation.
Features
1. High Storage Capacity:
- Large Storage Space: With 320 GB, the hard drive offers plenty of space for operating systems, applications and data, making it suitable for most desktop applications.
2. Good Performance:
- Fast Access Speeds: The 7,200 RPM rotation speed ensures fast read and write speeds, which improves system performance and response times.
3. Cache Memory:
- 16 MB Cache: The cache helps optimize performance by caching frequently used data and enabling faster access.
4. Reliability:
- High MTBF: The high mean time to failure (MTBF) indicates a reliable and long-lasting hard drive.
5. Energy Efficiency:
- Moderate Power Consumption: The moderate power consumption ensures that the hard drive is relatively energy efficient, which lowers running costs and reduces heat generation.
Application area
1. Desktop PCs:
- Primary or secondary drive: The hard drive is ideal as a primary drive for the operating system and applications or as a secondary drive for additional data storage in desktop PCs.
2. External storage solutions:
- External enclosure: The hard drive can be used in external enclosures to provide an external storage solution for backups or additional data storage.
3. General data storage:
- Home and office applications: For general data storage needs in home or office applications, the hard drive offers sufficient capacity and performance.
4. Upgrade for older systems:
- System upgrade: The hard drive can be used in older computers to increase storage capacity and improve system performance.
5. Backup solutions:
- Data backup: The large capacity and good performance of the hard drive make it a suitable choice for storing backups and archive data.
