EDU shared drives
ARE DEAD now after recent Google policy changes, unlimited storage thing is now vanished, user can only request x amount of limited storage after paying y amount of money. If you want to continue your journey in Google Drive with more space then only way is to purchase any of their subscription based on your usage else migrate to any other trust worthy service which you like. If you are going to make own shared drive generator then time is gone, unlimited storage thing is gone and Google will terminate your subscription for abuse. In simple words, now no one can provide you unlimited storage in Google Drive.
BTW, old MsGsuite users enjoyed the unlimited storage a lot no doubt and made Google Drive API RIP cloning PBs of data using SA. If you are looking for free large amount of storage for non-confidential & piracy stuff then you can checkout
TeraBox or
GoFile or maybe Telegram itself.
