I've never done this HDD/SSD replacement procedure before, so would appreciate some assistance. I want to purchase a new 2TB SSD as the replacement and copy the old HDD's files to the new SSD. What is the best quality 2TB SSD that is compatible with this Dell XPS 8700? Will I need to buy a SSD caddie or extra cables? How do I best transfer the old files to the new drive. The less complicated, the better. Also, price is a consideration, but I want a high quality SSD.
