WDC WD2502ABYS-02B7A0
The WDC WD2502ABYS-02B7A0 is a hard drive from Western Digital that belongs to the WD RE series. This series is designed for use in enterprise environments and demanding server applications. Here is a detailed description of the technical details, features and application areas of this hard drive:
Technical Details
1. Capacity:
- 250 Gigabytes (GB). This capacity is relatively small by modern standards, but can be useful for certain applications and as secondary storage or in RAID configurations.
2. Form Factor:
- 3.5 inches. This is the standard form factor for desktop and server hard drives used in most server chassis and desktop PCs.
3. Interface:
- SATA II (3 Gb/s). This interface supports a maximum data transfer rate of up to 3 Gb/s. This is slower than the newer SATA III (6 Gb/s), but sufficient for the time of release.
4. Rotational Speed:
- 7200 RPM (revolutions per minute). This rotational speed provides higher performance in read and write operations compared to 5400 RPM hard drives, making it suitable for server and demanding applications.
5. Buffer Size (Cache):
- 16 MB. Cache memory helps improve performance by caching frequently accessed data, thus reducing response times.
6. Average Access Time:
- Approximately 8.9 milliseconds. This time measures the amount of time it takes the hard drive to access a specific data location and affects the overall data retrieval performance.
7. Fault tolerance and reliability:
- MTBF (Mean Time Between Failures): Typically over 1,200,000 hours. This number indicates high reliability and longevity of the drive, which is important for use in mission-critical environments.
8. Power consumption:
- Operating: Approximately 8.4 watts.
- Idle: Approximately 6.4 watts. Power consumption is typical for enterprise hard drives, with higher power consumption corresponding to higher performance.
9. Operating and environmental conditions:
- Operating temperature range: 5 to 55°C.
- Storage temperature range: -40 to 70°C.
- Noise level: Operating approximately 32 dB, idle approximately 29 dB. Noise levels are slightly higher than desktop hard drives, but acceptable for server environments.
Features
1. Enterprise Quality:
- The WD RE Series is designed for 24/7 operation and for use in mission-critical applications, including servers and storage arrays.
2. RAID Optimization:
- The drive supports RAID configurations and is optimized for use in RAID arrays, providing reliable performance and fault tolerance for RAID systems.
3. Advanced Error Correction Technologies:
- The drive uses advanced error correction technologies such as ECC (Error Correction Code) and other methods to ensure data integrity and minimize data errors.
4. Vibration Tolerance:
- The WD2502ABYS-02B7A0 is equipped with technologies that detect and compensate for vibrations in server and storage environments to improve performance and reliability.
5. High-Duty Cycle Operation:
- The hard drive is designed for continuous operation in demanding environments where it must continuously handle high loads.
6. Fault tolerance and hot-swap support:
- It is designed to operate in hot-swappable environments where hard drives can be replaced without shutting down the system.
Application area
1. Server environments:
- Ideal for use in servers where reliability, performance and high availability are required. The WD2502ABYS-02B7A0 is optimized for continuous workloads and mission-critical applications.
2. RAID systems:
- Great for use in RAID arrays, especially in RAID 5 or RAID 6 configurations where fault tolerance and data integrity are critical.
3. Storage arrays:
- Can be used in large storage arrays to provide high storage capacities while maintaining performance and reliability.
4. Backup systems:
- The hard drive is also suitable for backup and archiving applications where high availability and data integrity are crucial.
5. Enterprise storage solutions:
- Well suited for enterprise storage solutions where a combination of high performance, reliability and durability is required.
In summary, the WDC WD2502ABYS-02B7A0 offers robust performance and reliability for enterprise environments. With its combination of high rotation speed, advanced error correction technologies and RAID compatibility, it is a suitable choice for demanding server and storage applications where continuous operation and data integrity are of utmost importance.
