There are only two "wire format" types: sc16 and
sc8 

For sc16 (16-bit I 16-bit Q): 

10MS/s * 32-bits = 320Mbits/second


For sc8 (8-bit I 8-bit Q): 

10Msps * 16-bits = 160Mbits/second 

Now,
if you're talking about the host side and doing calculations for disk
writes or something, then, fc32 is 32-bits I 32-bits Q: 

10Msps *
64-bits = 640Mbits/second 

= 80Mbyte/second
