Heads up, the Internet Archive will potentially dark your items and ban your account if they feel these uploads are not of cultural significance (it costs them $2/GB to store uploaded data). They do this currently for folks who try to dump Twitch content into the storage system.

Consider Wasabi or Backblaze B2 for reduced storage costs vs S3. They might also issue you a Vault [1] account if you're willing to pay to store these objects.
