The WD Caviar SE16 400 GB Gets Ready to Face The World

Western Digital Nomenclature Explained

Regular WD UltraATA drives are named based on their capacity followed by either the suffix BB (indicating 2 MB cache) or JB (8 MB). Serial ATA models are given the suffix JD ; they all feature 8 MB cache. If you come across a drive labeled JS, this is a SATA II model with 8 MB cache memory. Should you want the 16 MB cache option, it is a KS breed you need to look for.
