45.51 seconds per magabyte represents the maximum throughput for
serial communication at 230,400 bps.  No driver for the MicroDrive
module could achieve that due to the fact that the module will only
transfer 512 bytes for each READ command.  You really need to include
the command overhead when calculating the device's throughput
capability.

The datasheet also states that the device takes some time to respond
to each command, but doesn't say how much.  I believe that will depend
on the particular MicroSD card that is being used.
