mSATA vs. M.2

What is exactly the difference between these two types of SSDs? I've heard that M.2 SSDs are supposed to be faster than mSATA but many high performance gaming laptops still use mSATA, and very few machines use M.2 sata. What exactly is the difference, and which one is better in general? Also, is M.2 sata a primary hard drive slot or more of a secondary slot such as the mSATAs?
