This video is just excellent because he explains not only how to replace the ribbon cable, he shows as well one of the (multiple) reasons why the ribbon cable fails sometimes even repetitive (which is costly) and how to pretend at least one of the reasons for ribbon cable failure.
The point is that manufacturing the unibody includes a fine treatment of the OUTER surface of the unibody but the inner side rests rough on microscopic level, so keeping its abrasive potential forever. This is a sort of design flaw concerning the manufacturing process made by apple.
(If you ask me: This should lead to a "extended replacement program" . Apple shurely will deny any responsibility as they always do… )
The method for prevention may even serve as a short test to confirm a defective ribbon cable - if you have HDD/SSD related issues - just try the trick. If is resolves your problem, you are shure that you need only exchange the cable. But: If the issue is persistent, this does NOT exclude ribbon cable failure because the cable might already be too much damaged to work correctly.
Before replacing your ribbon cable don´t forget to protect the new cable as described in the video to prevent a second or even third failure of the cable because of the lack of finish of the inner side of the unibody surface!
