The WDC WD20EARX-00PASB0 is a 2 TB internal hard drive from Western Digital's Caviar Green series. This hard drive is designed for use in desktop PCs and other storage systems and offers a mix of capacity, performance and energy efficiency. Here is a comprehensive description of the technical details, features and application areas of this model:
Basic description
Modell: Western Digital WD20EARX-00PASB0
Type: Internal Hard Drive (HDD)
Interface: SATA III
Capacity: 2 TB
Form factor: 3.5 inches
Speed: 5400 rpm
Cache: 64 MB
Technical details
1. Interface:
- SATA III (SATA 6 Gb/s): This interface enables a maximum data transfer rate of up to 6 Gb/s (600 MB/s). SATA III is backwards compatible with older SATA versions, ensuring broad system compatibility.
2. Form factor:
- 3.5 inch: Standard size for desktop hard drives. This size is widely used and fits most desktop PC cases and some external hard drive enclosures.
3. Capacity:
- 2TB: Offers generous storage capacity suitable for a wide range of uses including operating systems, applications, games and large amounts of data such as photos, videos and music.
4. Speed:
- 5400 RPM: This speed is lower than the more common 7200 RPM hard drives. It provides better energy efficiency and lower noise, but slightly lower performance in data access and transfer rates.
5. Cache:
- 64 MB: The cache stores temporary data and helps improve hard drive performance by delivering frequently accessed data more quickly.
6. Search times:
- Average access time: Approximately 8.9 ms, which describes the average time required to access a specific data location.
7. Fault tolerance:
- SMART Support: The hard drive supports SMART (Self-Monitoring, Analysis, and Reporting Technology), a system for monitoring hard drive health and providing early warning of possible failures.
8. Power consumption:
- Typical power consumption: Approximately 6.0 watts when operating and approximately 5.0 watts when idle. Energy efficiency is optimized, especially with a 5400 rpm drive, which lowers power costs and reduces heat generation.
Features
1. Energy efficiency:
- Low power consumption: The WD20EARX is optimized for low power consumption, making it an energy efficient choice for desktop PCs and reducing operating costs.
2. Quiet performance:
- Low Noise: Due to the lower rotation speed of 5400 RPM, the hard drive runs quieter than models with higher rotation speeds, which reduces the noise level in the system.
3. High capacity:
- Large Storage Space: With 2TB, the hard drive offers plenty of space for a variety of data, making it ideal for applications that require a large amount of storage space.
4. SMART technology:
- Failure Prediction: SMART technology continuously monitors the health of the hard drive and provides early warnings to prevent data loss and extend the life of the hard drive.
5. Performance in everyday life:
- Good performance for everyday use: While the 5400 rpm speed results in slightly lower performance, the hard drive still offers sufficient speed for everyday use and storing large amounts of data.
Areas of application
1. Desktop-PCs:
- General Applications: Ideal for desktop PCs that require large storage capacity and where energy efficiency and low noise are valued.
2. Multimedia storage:
- Media File Storage: Good for storing photos, videos and music, especially when large amounts of data need to be managed.
3. Backup solutions:
- Data Backup: Can be used as a backup drive to back up and restore important data.
4. Home-Server:
- Home Servers and NAS: Well suited for use in home servers or Network Attached Storage (NAS) systems where large storage capacity and energy efficiency are important.
5. System-Upgrades:
- Expansion of storage capacity: A good choice for upgrading existing systems that require more storage space without significantly increasing the total cost of ownership.
Summary
The Western Digital WD20EARX-00PASB0 is a 2 TB internal hard drive with a SATA III interface, a speed of 5400 rpm and a 64 MB cache. The hard drive offers a high storage capacity and is characterized by its energy efficiency and quiet operation. It is particularly suitable for desktop PCs, multimedia applications, backup solutions and home servers. With support for SMART technology, the hard drive ensures reliable monitoring of hard drive health and an extended service life. Despite the slightly lower performance compared to faster hard drive models, the WD20EARX offers an excellent balance between performance, capacity and energy efficiency for a wide range of applications.
