Western Digital WD2500JB Internal Hard Drive Data Storage

Cool, quiet operation, superior performance and industry-leading reliability make these EIDE drives ideal for desktop, business, and consumer electronics storage.

Fast - 8 MB cache - Keeps more of your data in high-speed memory for unsurpassed performance in its class. Fast 7200 RPM spindle speed and EIDE (Ultra ATA/100) for burst transfer rates up to 100 MB/s. For even higher performance, consider WD Caviar SE16 SATA 3 Gb/s hard drives.

Cool - Cool operation results in the highest reliability, even in intensely hot environments such as digital video recorders. That's why these, the coolest on the market, are the drives of choice for the world's leading consumer electronics and PC manufacturers.

Quiet - The technology that Tom's Hardware Guide called "very fast and nearly silent" is used throughout this family of drives. Our WhisperDrive™ technology minimizes noise to levels near the threshold of human hearing. To cut seek noise, SoftSeek™ technology streamlines read/write seeking algorithms, resulting in more efficient operation.


Ideal For

High-performance family and business computing. These drives easily handle photo editing and data-intensive multimedia applications. For even higher performance, consider WD Caviar SE16 SATA hard drives.

- ShockGuard™ instantaneously protects the hard drive against damage from bumps and vibrations while it is running. This technology enables WD Caviar drives to achieve industry-leading shock specifications.






8 MB Cache

Our high-performance hard drives provide a higher percentage of cache hits and significantly faster time to data than industry-standard 2 MB versions. Within the complex operations of hard drives, the buffer is used to hold the results of recent reads from the disk and also to "pre-fetch" information that is likely to be requested in the near future. The use of an increased buffer improves the performance by reducing the number of physical accesses to the disk and allowing data to stream from the disk uninterrupted by mechanical operations.
Data Lifeguard™ is an expanded set of protection tools which include shock protection, an environmental protection system, and embedded error detection and repair features that automatically find, isolate, and repair problem areas that may develop over the extended use of the hard drive.

Data Lifeguard Tools™ is a set of software utilities that work in conjunction with the embedded Data Lifeguard features to make hard drive installation, drive management diagnostics, and repair simple and worry-free.

IMPORTANT: Use Data Lifeguard Tools 10.0 or later installation software to access the full capacity of your hard drive. Hard drives larger than 137 GB require a controller card to utilize full drive capacity.
