Not a problem. If the drives have different performance, 
some files may have different performance, but that's 
actually nothing new because the outside of a disk platter
is faster than the inner tracks. So whether you have one 
disk, two matched disks, or two mismatched disks you'll 
always have different areas with different performance.
