In one line

A flat per-GB toll on everything it moves, either direction, layered on whatever S3 and EFS already charge.

What gets missed

The per-GB fee ignores direction and is only DataSync's cut. S3 LIST, HEAD, GET and PUT requests plus any cross-Region transfer bill on top, and Enhanced mode adds a charge per task execution.
