Mini-SATA (abbreviated as mSATA), which is distinct from the micro SATA connector, was announced in 2009.
The connector is similar in appearance to a PCI Express Mini Card interface, but is not electrically compatible; the data signals need a connection to the SATA host controller instead of the PCI Express host controller.
