Western Digital 80GB 7200RPM 8MB Cache IDE Bulk/OEM Hard Drive WD800JB

Product Description ULTRA/ATA-100 SPECIAL EDITION *OEM* From the Manufacturer WD Caviar SE hard drives are designed to maximize desktop computer performance for activities requiring high-performance storage such as computer gaming, digital video editing, and file server applications. Offering capacities as large as 250 GB and equipped with an 8 MB buffer -- the largest buffer available today in a desktop EIDE hard drive -- the WD Caviar SE family delivers data to users faster than any hard drive in its class. Selected models are available with Fluid Dynamic Bearing (FDB) technology, perfect for noise-sensitive computing environments.Superior Performance SE 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 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 Protection Enhancements Data Lifeguard is an expanded set of data protection features that 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. With these enhanced data reliability features, the drive can perform more accurate monitoring and 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 for WD Caviar SE drives. Shock Guard allows instantaneous data protection at high shock values to achieve leading shock specifications.
