An mSATA drive is a solid state drive that has a very small form factor. It looks like a large integrated circuit, it's basically an SSD without the 2.5 housing. It originally was a relatively small size, typically 16 GB or 32 GB, and was used to cache the hard drive.
However, now with larger mSATA drives of 128 GB or more, they can be used as a regular SSD to hold the operating system on instead being used to cache a hard drive. eSATA stands for external SATA. It is a way to connect external hard drives to a system. It allows native SATA speeds for external drives.
