speed of data transfer through the bus.

sdr single data
ddr double data

128 sd @ 233 is a 233MHz data rate
128 dd @ 233 is equivalent to about 466MHz sd
( not quite the exact speed change, but ddr is far faster than sdr )

oops posted answer to wrong question.

but the 80 pin will be faster data transfer than the
68 pin

The 80pin connector, has the same 'bus' connections as a 68pin device. It is designed for use in a 'hot swap' frame, where the extra connections provide power, and control of the device ID. The frame would then have a normal 68pin connection to the SCSI host. The 'downside' for a single drive, is that with the 80pin device, you would need an adapter, and this can introduce signalling problems, especially at the higher data rates. However with the proper frame (assuming it is designed to handle U320), the 80pin device provides easy drive changing, without having to worry about setting the ID's.

As far as speed is concerned, there is no difference
