And, this method has its own set of limitations. Such as,

  • Only a limited number of users can use this method since it is accessible in only a few countries.
  • You need to pay $2 per GB of data, i.e. if you want to upload 1TB of data then you will have to pay $2000 which is not cost-effective.
  • More importantly, you can only ship 10 drives at one go and you can’t upload more than 300 folders using this method.
