Just an informational note.
I attended a talk at a local SA group about tape technology presented by a FUJI
rep.
One of the interesting things at that talk was that some newer formats/drives
have "adaptive compression". The drive compresses data to onboard memory
rather than to tape and if the data did not compress writes the original
data to tape. It does this dynamically, even within a single tape file.
