ITEM# WD800JB Description: Western Digital Caviar SE 80Gig, 7,200RPM, ATA100, 8Meg Cache

WD Caviar SE hard drives utilize an 8 MB buffer -- four times the industry norm -- to increase performance levels higher than any other IDE hard drive

Individuals believe seek time represents a hard drives performance. In reality, it's a combination of media rates, buffer sizes and host rates, as well as seek and spin times. Western Digital is committed to a drive's overall "integrated" performance, thereby optimizing the entire system. Know that there's more to drives than just speed alone before someone pulls a fast one on you.
