I want to remove the hybrid drive as it has bad sectors and upgrade M.2 2280 SSD to 2TB  Yes, you can do that. No, you do not need to buy another hybrid drive, you can just leave that drive bay empty. You may buy any M.2 2280 SSD. Yes, you may upgrade to 2 TB, or you can upgrade all the way to 4 TB if you want. Here are some Crucial SSDs that are compatible, though any major brand will be fine. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard. (Repeatedly touching a metal case part is not sufficient mitigation with modern components.)
Below are my Hard Disk specifications which show One Hybrid Drive and One SSD,  [IMAGE]  I have a couple of questions 1. If I search by part # 3VFCP, I think the SSD is of form factor 2280.  Am I missing anything? 2. Can I replace Hybrid Drive completely and install a single SSD, is it recommended? 3. Some SSDs are available with heat-sink, any advice for this? I doubt there is space available for the external heat sink. I have only a reference of photos available in the manual. Thank you 
m15 R1, advice for SSD upgrade?
