The big S stands for samples, so 10MS/s in the scientific world means10MHz sampling rate in the audio world. But this high-rate AD/DA-unitsaren't necessarily operating with data streams. The 4GS/s digitizershere at work only produce chunks of data and there is quite some timeneeded to fetch this data over PCI into the PC. So it isn't reallyusable for audio or audio-like experiments...
