[Title] mSATA [Description] 
An mSATA is a micro-sized SSD that looks like a thin module - it's designed for thin notebooks (ultrabooks) like the MacBook Air. Like all other SSDs, it replaces the hard drive. (The unit itself is called an mSATA because it uses a low-profile or "mini SATA" interface.)
