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.
