Yes, we have measurements that prove this point but unfortunately the
vendor that collected this data does not allow us to publish that data.

Reducing energy consumption matters for mobile devices. There are other
applications for copy offloading, e.g. in data centers and in enterprise
applications. I don't think that these other users care as much about
reducing energy consumption as we do.

Every LFS for zoned storage has to perform garbage collection, isn't it?
I think that we can discuss copy offloading without having to discuss
filesystem implementation details.

Thanks,
