What physically corresponds to /dev/sda and /dev/sdb isn't necessarily 
predictable these days.  For example you can initialize a single drive 
as a volume with some common raid controllers, then swap that drive's 
position in the drive bays or reverse a pair and each will still show as 
the /dev/sd? device where it was initialized instead of what you'd 
expect from the current location.
