I'd like to know the opinions of other integrators; Is there any reason to choose the PCI-6221 over the USB-6221?
In our particular case, the USB platform seems to be the better way to go. But there is some concern that even though the acquisition rates are reported as being the same, there may be some drawbacks to choosing the USB bus over the PCI. Could we end up seeing delays or "missed" data with the USB? What experiences have you had in the field with USB based acquisition? Your opinions are greatly appreciated.
