What is the proper way of adding SSD? I have my os and lots of my programs on my existing WD Caviar blue. . i have backed up all my files on my external HDD so i want to wipe it out now. . What is the right method of doing it? should i just let them both plugged on my motherboard? or should i just plug the SSD first and then plug my HDD after installing my OS on my SSD? i need some guidance here. . thanks in advance.
