Whenever you are talking about drives and how many are detected, then 
that is specific to the kernel, not Debian. The two disks will be most 
likely detected as individual disks because the SATA "hardware" raid is 
not supported by Linux. It would be helpful if you posted the output of 
`lspci -v` so that we would know what type of  raid controller, if any 
actually exists.

Anyway, in almost all cases (especially for the cheap raid solutions on 
mass-market motherboards), it is more efficient to set up two individual 
drives and set up software RAID in Linux on the partitions you want. 
Cheap hardware RAID is more of a gimmik than a real feature.
