What is the difference between these two.

My understanding is that FastSCSI has a trans rate of
10MB/sec.

At one time I was told they were the same, but the
my NeXT uses SCSI-2 and it only transfers at something
like 5MB/sec

Any help is appreciated.

SCSI-2 runs at 5MB/sec.  SCSI-2 FAST runs at 10MB/sec.  SCSI-2 FAST &
wide runs at 20MB/sec.  SCSI-2 FAST & double wide runs at 40MB/sec.
The NeXT has a SCSI-2 *connector* on the back.  It is running its bus
at 5.

It was my understanding that the NeXT uses a SCSI-2 CONNECTOR but was really  
SCSI-1 internally.
