A SATA connector consists of a signal connector and a power connector. The SAS
connector adds a bridge (primary physical link) between the signal connector and the
power connector. This means SAS backplane connectors can accept either drive type, but
SATA backplane connectors can ONLY accept SATA drives. Figure 3 shows these
connectors.
