Whether you clone the hdd to the ssd internal or external does not matter.
Clone to the ssd and then remove the hdd.
Connect the ssd to the hdd sata port....boot it up.
Set the hdd aside for a week or so while you test and if all is good you can do what you want with it.
received this response from samsung. "Also keep in mind that if you have a Desktop, you could just connect this drive as a secondary internal drive instead of using USB to SATA." i know that the article from **** Ngo was for laptops. can i install the ssd drive into my desktop, clone it and then reinstall as my main drive? then use hard drive as backup drive?
