Fact check: The cost of S3 standard storage per TB is approximately $23 not $153. S3 standard storage, the most expensive kind, is $.021-.023 per GB.

S4 costs about the same as S3 Deep Archive storage.

Update: The article appears to be a joke. That aside, there are no cost savings against S3 Deep Archive; additionally S3 Deep Archive supports restores unlike the write-only S4.
