The enhancement would be speedup of data reading on mirrored partitions. The idea is easy. If we have mirrored partition over 2 disks, and these disk are in sync, there is possibility of simultaneous reading of the data from both disks on the same way as in raid 0. So it would be chunk1 read from master, chunk2 read from slave at the same time. As result it would give significant speedup of read operation (comparable with speed of raid 0 disks).
