Serial Advanced Technological Attachment (SATA).
Its the most used HDD technology right now and you should go with it. WD Caviar 640GB is SATA.
SATA2
Newer and a little faster but less used and less supported.
eSATA
external SATA for external HDDs.
I dunno which HDD you are using. Can be PATA or SATA or IDE.
Stick with the above mentioned HDD and you will be fine.
