The maximum bit transfer rate (MBTR):
- (Of solid state storage equipment): "the number of data bits per second transferred between the equipment and its controller."
- “MBTR” (bits per second) = B x R x T, where:
- B = Maximum number of data bits per track available to read or write in a single revolution;
- R = Revolutions per second;
- T = Number of tracks that can be used or written simultaneously."
