I picked up an Asus gaming laptop a year ago since my old one was on its last leg but this "performance" laptop has been slow as dogsh*t (I've had 3 Asus laptops and always had great experiences with them and the best customer support to back). Apparently this 'pooter has the processing power but is limited because of the garbage 8GB ram and HDD (I think the HDD has issues because I can hear the clicking noise that's often associated with a dying HDD). Well, I'm upgrading the RAM but I'm corn-fused on the HDD. I know Sata SSD has been around for quite some time now but I just discovered my laptop supports M.2. I had no clue what this was 10 minutes ago. I found some info on the YoosToobs but still not sure how it works. I found which style my laptop supports but can I ditch the HDD and just use the M.2 if I get a big one or do I still need a HDD/Sata SDD and still use the M.2 to load the OS? I don't mind having an Sata SSD and M.2 but not sure if that's necessary?
