A method and a system for scheduling transmission of a plurality of input/output (I/O) operations to be executed by a storage device comprising: applying a slidable cell window to sequential I/O operations from a scheduled sequence, the slidable cell window being positioned over the sequential I/O operations starting with the first I/O operation, transmitting to the storage device the sequential I/O operations, receiving an operation execution confirmation from the storage device, determining a position of a given cell of the slidable cell window associated with the I/O operation, responsive to a position of the given cell being the first position of the slidable cell window: sliding the slidable cell window over the plurality of I/O operations so as to include at least one additional I/O operation in the slidable cell window, and transmitting to the storage device, the at least one additional I/O operation for execution.
