It sounds as though your throughput is limited by disk read head time - 
splitting across physical disks increases that resource.

You *may* be able to improve the efficiency of one drive by using NIO 
non-blocking reads to keep more disk prefetch reads going at once. Given a pool 
of reads, the drive can optimize their order to reduce total head movement, and 
therefore time the read head wastes not actually doing a transfer.
