Free overseas cloud storage

The free online disk services provided domestically are of a lower class compared to those from abroad. Whether it's the total size of the space or the size of individual files, there is a significant difference. Moreover, domestic cloud disks, such as NetEase's, require积分 (积分), and NetEase's yeah.net email only provides 20MB of free space, which is really useless. I have selected six foreign free online disks for evaluation.
