WDC WD20EADS-65R6B1 ATA Device
The WDC WD20EADS-65R6B1 is a hard drive from Western Digital released in 2009. It belongs to the WD Caviar Green series, which is known for its energy efficiency and quiet operation. Here are the key technical details, features and application areas of the WD20EADS-65R6B1 in detail:
Technical Details
1. Capacity:
- 2 terabytes (TB), which is equivalent to 2,000 gigabytes (GB). This provides enough storage for large amounts of data, including photos, videos, music and documents.
2. Form Factor:
- 3.5 inches, which is the standard size for desktop hard drives. This size fits most desktop PCs and external hard drive enclosures.
3. Interface:
- SATA II (Serial ATA II), also known as SATA 3Gb/s. This interface enables data transfer rates of up to 3 Gb/s, which is sufficient for most applications, although newer interfaces such as SATA III (6 Gb/s) offer faster transfer rates.
4. Rotational Speed:
- 5400 RPM (revolutions per minute). The lower rotational speed compared to the more common 7200 RPM results in quieter operation and lower power consumption, but compromises the maximum data transfer rate.
5. Buffer Size:
- 64 MB Cache. Cache memory is used to temporarily store data to improve performance and reduce access times.
6. Average Access Time:
- Approximately 8.9 milliseconds. This time is the average amount of time it takes the hard drive to access a specific data location.
7. Fault Tolerance and Reliability:
- The hard drive uses error correction and monitoring features to ensure data integrity, but is not optimized for use in demanding RAID-stored server environments, but rather for desktop or personal use.
8. Operating and Environmental Conditions:
- Operating temperature range: 0 to 60 °C.
- Storage temperature range: -40 to 70 °C.
- Noise level: During operation approximately 29 dB, during idle approximately 22 dB.
9. Power consumption:
- During operation: Approximately 6.8 watts.
- During idle: Approximately 5.5 watts.
- This is an indication of the energy efficiency of the hard drive, which is especially beneficial in green computers and networking solutions.
Features
1. Green technology:
- The WD Caviar Green series is designed to minimize energy consumption, which is achieved through the lower rotation speed and various power management features. This helps reduce running costs and the environmental footprint.
2. Low noise technology:
- The hard drive is designed to operate more quietly compared to faster hard drive models. This is especially beneficial for applications where quiet operation is required, such as multimedia or home office computers.
3. Power Saving Features:
- The WD20EADS includes features such as automatic spindle speed adjustment and an automatic read/write head parking mechanism to further reduce power consumption when the hard drive is not actively in use.
4. Error Prevention Technology:
- The hard drive uses technologies such as SMART (Self-Monitoring, Analysis, and Reporting Technology) to detect and prevent potential errors early.
Application
1. Desktop PCs:
- Due to its capacity and power efficiency, the WD20EADS is well suited for desktop computers, where it can be used as the primary hard drive for the operating system and applications, or as a secondary hard drive for data archiving and backup.
2. Home and Multimedia PCs:
- Its quiet operation makes it ideal for home PCs where quiet operation is important, such as when used for multimedia applications such as music or video editing.
3. External Storage Solutions:
- In an external hard drive enclosure, this hard drive can be used as a portable backup drive or for storing large amounts of data.
4. Not for Servers or RAID Arrays:
- Due to its lower speed and design, it is not optimized for use in servers or RAID arrays where higher data transfer rates and robustness are required.
Overall, the WD20EADS-65R6B1 offers a balanced combination of capacity, energy efficiency and quiet operation that makes it a good choice for home and office applications, while it may not be suitable for particularly demanding, business-critical applications or high performance requirements.
