They all refer to the same physical 4TB SAS 12G 7.2K LFF drive. MB004000JYDPB, this page, is an OEM model number: the identifier printed on the drive itself by the manufacturer. 872487-B21 is the HPE option kit number used when ordering the drive as a sales item. 872745-001 is the HPE spare number used for replacement fulfilment.
