Fast SCSI
Data transfers up to 10 megabytes per
second, first defined in SCSI-2, below defines how it is used in the different generations
of the SCSI standards.
8 bit SCSI asynchronous commands with
Synchronous data transfer rates up to 10 megabytes per second. Bipolar technology with
Open collector or active negation single ended bus transceivers, passive or active
termination, and Differential (Now called HVD – High Voltage differential) bus
transceivers based on EIA 485 allowed in SCSI-2.
SCSI SPI (SCSI Parallel Interface)
8 bit SCSI asynchronous commands with
Synchronous data transfer rates up to 10 megabytes per second. CMOS technology with Open
Drain or active negation single ended bus transceivers, passive or active termination, and
Differential (Now called HVD – High Voltage differential) bus transceivers based on
EIA 485 allowed in SCSI SPI.
SCSI SPI-2 (SCSI Parallel Interface)
8 bit SCSI asynchronous commands with
Synchronous data transfer rates up to 10 megabytes per second. CMOS technology with Open
Drain or active negation single ended bus transceivers, active termination, LVD (Low
Voltage Differential) and Differential (HVD – High Voltage differential) bus
transceivers based on EIA 485 allowed in SCSI SPI-2.
