The Western Digital Caviar SE delivers outstanding performance with a 7200RPM spindle speed and SATA 300 MB/s interface. SUch speed gives you a cold start in only about 9 seconds. 80GB gives you room to store all manner of possible programs and applications. The hard drive has an 8MB buffer, maximizing data transfer from buffer to host at 3.0 GB/s, and from buffer to disk at 748Mbits/s. The minimal non-recoverable error rate of 1 in 1014 and start/stop cycles make this disk remarkably reliable. 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. With wide compatability, exquisite performance and solid reliability, WD gives us another great offering to bring to you! Cache: 8MB Parts: 3 years limited Labor: 3 years limited

The Western Digital Caviar SE Hard Drive is a clear leader in the race for the peak of desktop drives. Its 80 GB runs at 7200 RPM with up to 100 MB/s transfer rates. Its breakthrough 8 MB cache makes this hard drive suitable for high-performance home and business computing, as it can handle both data-intensive applications and high-end multimedia applications. It offers average latency of 4.2 ms with an average seek time of only 8.9ms, and an average write time of 10.9ms, resulting in both greater efficiency and safer data transfer. This hard drive incorporates WD"s Data Lifeguard, an exclusive set of data protection features, including shock protection, environmental protection, real-time embedded error detection and repair. Its mechanism ensures automatic discovery, isolation, and repair of problems which may develop in a hard drive. Despite a remarkable data transfer rate, WD's WhisperDrive makes the drive almost silent. The most common hard drive failure is due to shocks: ShockGuard protects the drive against damage from bumps and vibrations, and the stainless steel casing completes the protection, keeping it safe up to 250Gs while working, and 900Gs idle. Its SoftSeek technology offers smooth operation of read/write seek function, reducing seek noise, while the DuraStep Ramp technology locks the heads in a secured position, even when power is off.
