An ink cartridge includes: an ink accommodating unit; and a storing unit. The ink accommodating unit is configured to accommodate ink therein. The storing unit is configured to store time length data indicative of a length of time to be taken by the ink cartridge to move from a first position to a second position different from the first position, the first position and the second position being defined within a mounting unit in a recording device, the ink cartridge reaching the first position before reaching the second position when the ink cartridge is mounted in the mounting unit.
