SCSI
Small Computer System Interface: a family of standards for attaching and commanding disks, whose Linux disk layer also drives SATA and USB disks.
In more detail
Disks that go through the SCSI layer are named sd followed by a letter, and optical drives sr followed by a number. SAS, Serial Attached SCSI, is the server version of the same command set.
