Western Digital Caviar 250GB Hard Drive

The WD Caviar® 250 GB Hard Drive is equipped with an 8 MB buffer - the largest buffer available today in a 7200 RPM desktop EIDE hard drive, delivering data to users faster than any hard drive in its class. Your new Western Digital hard drive comes with an IDE interface cable, mounting screws, jumpers, installation poster, and Data Lifeguard Tools installation software and utilities. Superior Performance This hard drive provides 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™ Data Lifeguard is an expanded set of data protection tools that includes shock protection, and 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. With these enhanced data reliability features, the drive can perform more accurate monitoring, error repair, and deliver exceptional data security. 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. Shock Guard™ provides outstanding improvements in shock and vibration protection. Shock Guard allows instantaneous data protection at high shock values to achieve leading shock specifications. Ultra ATA/100 Western Digital hard drives set the industry performance standard by providing Ultra ATA/100 technology. This interface allows for data transfer rates of up to 100 MB per second, 50 percent faster than Ultra ATA/66, resulting in increased performance and data integrity. Ultra ATA/100 is also backward-compatible. 7200 RPM Performance 7200 RPM hard drives provide 33 percent faster disk transfer rates than 5400 RPM hard drives. This performance boost yields perceptible improvement in real world reaction time on the PC. 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.
