The "ATA WDC WD2500AAJS-0" is a hard disk from Western Digital (WD) that is part of the WD Caviar series of SATA hard disks. The name "ATA WDC WD2500AAJS-0" refers to a model that was popular in the early days of SATA hard disk production. Here is a detailed description, technical details, features and application area of ​​this type of hard drive:
General Description
The Western Digital WD2500AAJS-0 belongs to the WD Caviar Blue series and is a 250 GB hard drive designed for desktop PCs and other computer applications. This hard drive uses the SATA interface but offers outdated performance and capacity compared to modern HDDs and SSDs. The WD2500AAJS-0 is designed to provide solid performance for general computer applications.
Technical details
- Model name: WD2500AAJS-0
- Storage capacity: 250 GB
- Form factor: 3.5 inches
- Interface: SATA I (SATA 1.5 Gb/s)
- Rotational speed: 7,200 rpm
- Cache memory: 16 MB
- Average access time: Approximately 8.9 ms
- MTBF (Mean Time Between Failures): Approximately 1 million hours, typical for hard drives of this time period
- Fault tolerance: No specialized fault tolerance or redundancy such as RAID, unless implemented by hardware RAID controllers.
Features
- SATA interface: The WD2500AAJS-0 uses the SATA I interface, which supports a maximum data transfer rate of 1.5 Gb/s. This interface is slower compared to modern SATA II (3 Gb/s) and SATA III (6 Gb/s) interfaces.
- Acoustics: The hard drive is designed to operate relatively quietly, typically with noise levels of around 30 dB(A) during operation.
- Power consumption: The power consumption during operation is approximately 8-10 watts, while idle it is approximately 6-8 watts. These values ​​are typical for hard drives of this generation.
- Data Integrity: The WD2500AAJS-0 uses error correction techniques to ensure data integrity during operation, but does not include advanced features such as comprehensive error correction or self-monitoring systems such as SMART (Self-Monitoring, Analysis, and Reporting Technology).
Applications
- Desktop PCs: The WD2500AAJS-0 is designed for use in desktop computers where it can be used as a primary or additional drive.
- Office Applications: Ideal for everyday office applications such as word processing, spreadsheets, and simple data storage.
- Home Entertainment: Suitable for applications such as storing media files, music, and videos when large amounts of data are not required.
- Budget Systems: The cost per GB makes this drive useful in systems where budgets are limited and higher capacity or faster speeds are not required.
Other considerations
- Compatibility: The WD2500AAJS-0 is compatible with all systems that support a SATA I interface. Modern systems that support SATA II or SATA III are backwards compatible, but performance is limited to the speed of the older SATA I interface.
- Replacement with modern hardware: Given rapid advances in storage technology, modern SSDs or larger and faster HDDs might offer better performance and capacity. The WD2500AAJS-0 is best suited for older systems or as a secondary drive for less demanding tasks.
Conclusion
The Western Digital WD2500AAJS-0 is a reliable, if now outdated, hard drive that offers a capacity of 250GB and is distinguished by its SATA I interface and 7200 RPM rotation speed. It is suitable for typical desktop applications and offers solid performance for its time, but with advances in storage technology and the availability of SSDs and larger HDDs, it is now more relevant for lower power systems or older computers.
