The invention relates to a device comprising a disk drive 1 for rotating a disk memory and at least one interface enabling a data flow between a rotating disk memory and at least one other module 10, 12. In order to enable a comfortable use of such a device, it is proposed that the device further comprises means 2 for setting the rotation speed of the disk drive 1 based on an indication of the data rate supported by an interface of the device, which interface is currently to be employed for enabling a data flow between the rotating disk memory and at least one other module 10, 12. The invention relates equally to a method setting the rotation speed of a disk drive 1 according to the capabilities of an interface enabling a data flow between a disk memory rotated by the disk drive 1 and another module 10, 12.
