[comp.sys.ibm.pc] Cheap v. Expensive SCSI host adaptor

roh@handel.CS.ColoState.Edu (lucas joon roh) (05/06/90)

Does anyone know what the real differences are between the cheap (<$100) and
expensive (~$300) SCSI adaptors?  Are the expensive ones that much better?
If so, in what ways?  Since most scsi drives have 8bit interface, what good
is it to have a 16bit host adaptor.  Also does the adaptors have anything to
do with the interleave (1:1 and 2:1 adaptors exist?).  
Do you also need special drivers for OS/2 and other OS's?
Yes, these are lots of questions and I would appreciate any kind of response.
Thanks,
Lucas
