A data storage device for reading and/or writing data to a storage medium includes a buffer memory (15) for smoothing the flow of data to/from the storage medium. Activation of the storage apparatus (9) to read/write data from/to the storage medium is generally controlled in dependence upon the amount of data held in the buffer (13). In order to optimize utilization of the buffer (15), it is proposed to adaptively set the threshold level at which such activation is effected. To this end, the utilization of the buffer (13) during a previous activation is monitored and a new threshold value is set in dependence on the monitored utilization parameter.
