SATA , SATA I 同 SATA II 有咩分別??

SATA is designed to be backwards and forwards compatible with future revisions of the SATA standard. Unfortunately, there are already documented incompatibilities between particular first-generation SATA-Ⅰ controllers and later-generation drives.



To address interoperability problems, some drive manufacturers have added a user-accessible jumper-switch, to select between SATA-Ⅰ and SATA-Ⅱ operation.



Users with a SATA-Ⅰ motherboard should either buy an ordinary SATA-Ⅰ hard disk, or buy a SATA-Ⅱ hard disk with the user-accessible jumper.
