SATA II and SATA III drives work on either style port. IME a SATA II SSD on a SATA II port will only deliver ~60% of the advertised performance if you are using a newer O/S like Win7. On earlier O/S's the performance is even lower and there is no SSD TRIM function in Vista or similar.
FYI to ALL - Imaging a Windows O/S can and often does result in an O/S that will not allow you to use the Windows Update feature meaning that you can no longer do security or other important updates. Microsucks tech support is clueless to the cause or a solution other than a fresh install. Microsucks online repair function claims to have found and fixed the problem when you run it but it doesn't. The cloning issue exists in all versions of XP, Vista, Win7 and it appears even in Win8 according to early reports.
Some people have found an inconsistent means to delete O/S files, change registry setings, then reestablish the files, etc. to resolve this issue on some but not all cloned drives. If being able to do Windoze updates is important to you, you may want to go to the trouble of doing a clean install and then transferring files which is a royal PITA due to Microsucks inability to write a proper O/S.
