Wide SCSI is a way to double the bus width, or number of data bits that can be transferred in a single clock cycle. To accomplish this, Wide SCSI uses a 68-pin cable, sometimes called a 'P' cable, capable of transferring data at 16 bits (2 Bytes) at a time compared to 8 bits (1 Byte) for a Narrow (50-pin) bus. As with narrow SCSI, Wide SCSI is available as Single-Ended, Differential, and Low Voltage Differential (LVD). Wide SCSI is capable of addressing up to 16 SCSI ID's (typically one controller and 15 devices)
