The WDC WD20EURS-63Z9B1 is an internal hard drive from Western Digital from the WD Green series. It is specially designed for use in consumer and desktop PCs as well as in external enclosures. Here is a comprehensive description of the hard drive, including technical details, features and areas of application.

General description


The WDC WD20EURS-63Z9B1 is a 3.5 inch hard drive with a storage capacity of 2 TB (terabytes). It uses the SATA II interface and is part of the WD Green series, which is known for energy efficient operation and quiet drive operation. This hard drive is well suited for applications where energy efficiency and quiet operation are more important than maximum performance.

Technical details


1. Form factor:
- 3.5 inch: The hard drive is the standard size for desktop hard drives. This allows easy installation in most desktop enclosures and systems.

2. Interface:
- SATA II (SATA 3 Gb/s): The hard drive uses the SATA II interface, which allows a maximum theoretical transfer rate of up to 3 Gb/s (approximately 300 MB/s). SATA II predates SATA III, but still offers adequate performance for most applications.

3. Capacity:
- 2 TB: The hard drive offers a generous storage capacity of 2 terabytes, making it suitable for storing large amounts of data, backups, and multimedia content.

4. Performance:
- Speed: The hard drive operates at a speed of 5400 RPM (revolutions per minute). This lower speed results in less heat generation and quieter operation compared to 7200 RPM drives, but may slightly slow down data transfer rates.
- Cache: The hard drive features a 64 MB cache, which temporarily stores frequently used data, improving performance.

5. Power consumption:
- Power consumption: When in operation, the hard drive typically requires around 6 to 7 watts, while when idle, power consumption drops to around 3 to 4 watts. These values ​​contribute to energy efficiency and reduce operating costs.

6. Design:
- Dimensions: The hard drive has the usual 3.5-inch dimensions of approximately 147 mm x 101.6 mm x 26.1 mm (length x width x height).

7. Compatibility:
- Operating systems: The hard drive is compatible with common operating systems such as Windows, macOS and Linux. Installation is usually done without special drivers because the hard drive is recognized as a standard SATA drive.
- Motherboards: The hard drive is compatible with motherboards that support a SATA connection.

8. Reliability:
- MTBF (Mean Time Between Failures): The WD20EURS-63Z9B1 offers a mean time between failure of approximately 1 million hours, indicating high reliability.
- Error Correction: The hard drive is equipped with error correction mechanisms to ensure data integrity and minimize data loss.

Features


1. Energy Efficiency:
- WD Green Technology: The hard drive is part of the WD Green series, which is known for its energy efficient operation. This helps to lower power consumption and reduce heat generation, benefiting both the environment and running costs.

2. Quiet Operation:
- Low Noise: With a rotation speed of 5400 RPM, the hard drive operates more quietly than models with higher rotation speeds, contributing to a quieter working environment.

3. Extended Capacity:
- 2 TB Storage: The generous capacity offers enough space for large amounts of data, backups and multimedia content, ideal for storing large amounts of data.

4. Performance Optimization:
- 64 MB Cache: The large cache improves the performance of the hard drive by temporarily storing frequently used data, increasing the data transfer rate.

5. Reliability:
- Error Correction: Built-in error correction mechanisms ensure that data integrity is maintained and the hard drive operates reliably even under intensive use.

Application Area


1. Desktop PCs:
- Primary Drive: The hard drive can be used as the main drive in desktop PCs to store the operating system, programs and personal data. The capacity is sufficient for most applications.

2. External Hard Drive Systems:
- Additional Storage: Can be used in external enclosures to provide additional storage space for data backup and archiving. The energy efficiency and quiet operation make it ideal for use in external enclosures.

3. Backup solutions:
- Data backup: The hard drive is well suited for regular backups of data and systems. The high capacity offers enough space for comprehensive backup solutions.

4. Multimedia applications:
- Storage of media files: The hard drive offers enough storage space for storing large media files such as photos, videos and music files. It is well suited for managing multimedia content.

5. Servers and NAS systems:
- Data storage: Can be used in small servers or NAS systems to provide additional storage space for data management and access.

Summary


The WDC WD20EURS-63Z9B1 is a 3.5-inch hard drive from Western Digital with a capacity of 2 TB and a rotation speed of 5400 rpm. It uses the SATA II interface and offers a 64 MB cache for improved performance. The WD Green series emphasizes energy efficiency and quiet operation. With its generous storage capacity, energy efficiency and reliability, the hard drive is ideal for desktop PCs, external storage solutions, backup applications and multimedia management. It offers a balanced combination of performance and energy efficiency for various storage needs.
