Ultra SCSI
A standard for SCSI data transfers. It allows a transfer rate of up to
20 Mbytes/s over an 8-bit SCSI bus and up to 40 Mbytes/s over a 16-bit
SCSI bus. STA (SCSI Trade Association) supports using the term “Ultra
SCSI” over the older term “Fast-20”.
Ultra2 SCSI
A standard for SCSI data transfers. It allows a transfer rate of up to
40 Mbytes/s over an 8-bit SCSI bus, and up to 80 Mbytes/s over a 16-bit
SCSI bus. STA (SCSI Trade Association) supports using the term “Ultra2
SCSI” over the term “Fast-40”.

Wide SCSI
A SCSI-2 feature allowing 16-bit or 32-bit transfers on the SCSI bus. This
dramatically increases the transfer rate over the standard 8-bit SCSI bus.
Wide Ultra SCSI
The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 40 Mbytes/s.
Wide Ultra2
SCSI
The SCSI Trade Association (STA) term for SCSI bus width 16-bits, SCSI
bus speed maximum data rate 80 Mbytes/s.
Word
A two byte (or 16-bit) unit of information.
