"Suedo-technical" means facts that don't agree with what you are pushing? >The short answer is... cable quality DOES make a differnence. Too short. Add "in some cases and is just a waste of money in other cases." >The long version from Adaptec comes from the design of SCSI U320 cables >and can be seen at and partially reproduced below: >http://www.adaptec.com/en-US/products/cables/_education/cables_u320.htm Ultra SCSI is not a good example to generalize from. Physically very different from a USB cable. Ultra SCSI uses a ribbon cable. There are no shields and there are no twists. Designs based on ribbon cables have to try all sorts of tricks to make up for ribbon cable problems. For example a ribbon cable may alternate a grounded wire with every wire that actually does something, thus creating a semi-shield over half the wire and also reducing crosstalk. The problems with this type of cable is why recent cable systems have given up parallel for serial: SATA, SAS, FireWire, USB, etc. ************************************************************************* ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *************************************************************************
