1. A recording apparatus that records data to a memory card, comprising at least one processor and/or at least one circuit which functions as:
a control unit configured to repeatedly transmit a data write command that includes information designating recording target data and a recording destination to the memory card which manages a memory for data recording in the memory card as a plurality of recording areas and which can execute data recording with a guaranteed minimum recording speed in units of recording areas,
wherein the control unit controls requesting the memory card to execute data recording with the guaranteed minimum recording speed or without the guaranteed minimum recording speed by a data write command, based on a combination of both of (i) whether or not a recording destination designated by the data write command is a start portion of one of the plurality of recording areas and (ii) whether or not the data write command includes data indicating a speed guarantee request,
wherein in a case of requesting the memory card to execute data recording with the guaranteed minimum recording speed, the control unit performs control to transmit a data write command that includes both of (a) information designating a start portion of a first recording area, which is one of the plurality of recording areas, as a recording destination and (b) the data indicating the speed guarantee request, and
wherein in a case of requesting the memory card to execute the data recording without the guaranteed minimum recording speed, the control unit (i) performs control to transmit a data write command that includes information designating, as a recording destination, a portion, different from a start portion, of one of the plurality of recording areas, regardless of whether or not the data write command includes the data indicating the speed guarantee request or (ii) performs control to transmit a data write command that includes, as a recording destination, information designating a start portion of one of the plurality of recording areas without including the data indicating the speed guarantee request.
