A method ( 2 ) of controlling memory usage in a portable streaming device ( 100 ), a portable streaming device ( 100 ) and a computer readable medium ( 110 ). The portable streaming device ( 100 ) comprises at least one memory ( 102 ), at least one processing unit ( 101 ), and at least one storage device ( 103 ) being operatively connected with said memory ( 102 ) under control of said processing unit ( 101 ). The size of a disk scheduler buffer memory within said memory in said portable streaming device is adaptively maximised by said method ( 2 ) at all times. Free memory available within the portable streaming device is continuously allocated ( 50 ) and at least a portion of said allocated free memory is designated as disk scheduler buffer memory ( 60 ). Thus results improved solid state memory utilisation of the portable streaming device, and due to larger available disk buffer memory size, less start-stop-cycles of the storage device are initiated, which leads to a longer life-cycle of said portable streaming device.
