This is from the SSD inside my Samsung Ultrabook. It's a 256 GB Samsung branded SSD which according to CrystalDiskInfo is connected to the Serial ATA interface.
I believe its an Samsung 830 series mSATA.Excellent SSDs, and very, very reliable. I bet that Ultrabook is quick with that SSD.
So it is a mSATA drive, that makes much more sense as the Ultrabook is so thin. Can't complain on the speed indeed Very happy with it!
