Abstract:
Provided are a storage device, controller, and method for using host transfer rates to select a recording medium transfer rate for transferring data to a recording medium. A host transfer rate of data with respect to a buffer is measured. Provided are a plurality of recording medium transfer rates at which data is transferred between the buffer and the recording medium. A determination is made of an amount of decrease in the host transfer rate. The recording medium transfer rate is selected based on the amount of decrease in the host transfer rate. A transfer rate at which the storage device transfers data is set to the selected recording medium transfer rate.
