If you are already using SAN storage, you can do a Flash Copy of the volumes in question. The thin provisioned target volumes will grow as data is changed. Wait 24 hours and the volumes will show a percentage indicating the amount of changed data.

This is now how thin provisioning works.

If one block of storage is updated multiple times, it's still just one block being allocated in the snapshot initially, but possibly rewritten many times. But for the sake of SAN sizing, those multiple updates also count toward SAN write traffic.
