These answers are next to useless, I just spent $200 on SSD's to find my laptop uses mSATA, a format I didn't even know existed. This is the exact reason I searched this topic in the first place: TO FIND OUT OF THERE ARE DIFFERENT SSD STANDARDS FOR LAPTOPS that I would need to check before buying.
My mistake for trusting the internet. Hope you all learn from my mistake. These forums are useless, open up your machine, it's the only way.
