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. Patricia
