Carrying on the heritage of WD Caviar SE hard drives as industry-leading performers, Western 
Digital offers WD Caviar SE Serial ATA (SATA) hard drives which feature capacities as large as 
250 GB and an 8 MB buffer, to fill acute demand in market segments such as high-end PC, 
workstation, and entry-level servers. Designers of enterprise storage systems and servers are 
increasingly using desktop-class, large-capacity SATA hard drives because of the advantages 
provided by the SATA interface. Benefits include a data transfer rate of 150 MB/s and 
improved cabling that enables greater system design flexibility. 

Product Benefits

!

8 MB cache 

– fast data transfer from a cache four times larger than the
