Migrating to a different storage provider is made easier because they all offer the same services and APIs. Users aren’t locked into providers because they rely on a particular feature of the provider. Also, files are content-addressed, enabling them to be transferred directly between miners without the user having to download and re-upload the files. Traditional cloud storage providers lock users by making it cheap to store files but expensive to retrieve them again. Filecoin avoids this by facilitating a retrieval market where miners compete to give users their files back as fast as possible, at the lowest possible price.
