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.
Caviar Drive Suffix | Cache | Interface |
---|---|---|
BB | 2 MB | UltraATA/100 |
JB | 8 MB | UltraATA/100 |
SB (RAID Edition) | 8 MB | Ultra ATA/100 |
JD | 8 MB | Serial ATA/150 |
SD (RAID Edition) | 8 MB | Serial ATA/150 |
JS | 8 MB | Serial ATA/300 |
KS | 16 MB | Serial ATA/300 |
YR (RAID Edition 2) | 16 MB | Serial ATA/150 NCQ |
The only suffix which is not part of this list is GD, which is used for the 10,000 RPM Raptor family drives, featuring 8 MB cache and the Serial ATA/150 interface.
