I just had to jump into this thread and say this:

The way I see it:
80MHz * 16bit = 160MB/s

This is output from kernel 2.4.1-pre10 with Justin's 6.0.9beta driver:

scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.0.9 BETA
<Adaptec 29160 Ultra160 SCSI adapter>
aic7892: Wide Channel A, SCSI Id=7, 32/255 SCBs

Vendor: IBM Model: DDYS-T18350N Rev: S80D
Type: Direct-Access ANSI SCSI revision: 03
(scsi0:A:6): async, 8bit
scsi0:0:6:0: Tagged Queuing enabled. Depth 32
Detected scsi disk sda at scsi0, channel 0, id 6, lun 0
async, 16bit
synchronous at 80.0MHz DT, offset 0x3f, 16bit
SCSI device sda: 35843670 512-byte hdwr sectors (18352 MB)
