1. A data transfer device comprising:
a processor to execute a program; and
a memory to store the program which, when executed by the processor, performs processes of,
acquiring sensor data detected by a sensor at a first data communication speed,
transmitting the acquired sensor data to an external server at a second data communication speed,
calculating a temporal transition of a predicted accumulation amount of the acquired sensor data in the memory using the first data communication speed and the second data communication speed,
determining whether or not the sensor data to be accumulated in the memory will overflow on a basis of the temporal transition of the predicted accumulation amount;
notifying a travel route on which a vehicle is scheduled to travel;
predicting and notifying a vehicle speed of the vehicle on the notified travel route; and
calculating the temporal transition of the predicted accumulation amount using the predicted vehicle speed in addition to the first data communication speed and the second data communication speed.
