A method may include transferring data between a host and a first storage device through a first storage interface, transferring data between the host and a second storage device through a second storage interface, and transferring data between the first storage device and the second storage device through a peer-to-peer channel. A storage system may include a host interface, a first storage device having a first storage interface coupled to the host interface, a second storage device having a second storage interface coupled to the host interface, and a peer-to-peer bus coupled between the first and second storage devices. A storage device may include a storage medium, a storage device controller coupled to the storage medium, a storage interface coupled to the storage device controller, and a peer-to-peer interface coupled to the storage device controller.
