SATA or mSATA drive shows as a SCSI device in Device Manager

This is working as designed. The system is reporting the storage devices as defined by the Intel Rapid Storage controller driver.

The Intel Rapid Storage driver version 12.6 (Released in March 2013) and newer versions classify all drives as SCSI devices for uniformity. This (and later) versions of the driver also allow for TRIM support (Allows for management of data blocks no longer in use) in SSD drives in RAID 0 arrays and other flexibility in operation of storage devices.
