US Patent 12008251 Rate levelling among peer data storage devices

Example storage systems, data storage devices, and methods provide rate levelling among peer storage devices. A master storage device among peer storage devices receives host commands, determines the workload states of the peer storage devices, divides the data units in the host commands into data blocks for data striping, allocates the data blocks among the peer storage devices, and sends the data blocks to the peer storage devices using a peer communication channel.
