Even with BDXL, which seems to be able to store up to 128GB per disc, you'd have to stack 100 of them to store the 12TB that an LTO-8 tape cartridge can store raw/natively. Tape cartridges also seem to be more physically durable than optical discs. This doesn't mean that they seem simply superior, though. I imagine optical discs have way better seek times, for example, even if read/write speeds are better with tape.
