It all depends on which disk controllers you're using and their
throughput.
I have two, separate SATA disks on two different SATA controllers and
read performance in a RAID-1 configuration *is* (nearly) twice that of a
single disk, in many situations. I think I've got the benchmark
statistics somewhere...
If "it appears it reads from one drive or the other" is the case, then
you probably have a bottleneck somewhere else. Are these disks on the
same controller channel?
