With the advanced features of btrfs, it would be an additional simple task to make different platters run in parallel. In this case, say a disk has three platters, and so three seek heads as well. If we can identify that much, and what offsets they are at, it then becomes a trivial matter to place the reads and writes to different platters at the same time. In affect, this means each platter should be operating as a single virtualized unit, instead of one single unit...
