> I see that LTO 6 holds 2.5T data per tape, or 6.25T compressed. The 6.25TB is only an estimate. If you have non compressible data you will get close to 2.5 TB of space on your tape. If you have all text files you may fit 15 TB on a single tape..

Just leave compression on at the HW level and make sure you have software compression off. HW compression will not slow down your backups and it will not reduce your tape if you have non compressible data.
