@ErgonWolf @ives @mhoye an LTO-9 tape stores 18 TB in a ~100x100x20 cartridge, so about 0.09 GB/mm^2. A microSD card can store 1TB and is 11x15x1, for a capacity of 6 GB/mm^2.
Magnetic tape is extremely cost efficient and durable but for sheer storage density microSD cards are very hard to beat.

@operand @ives @mhoye True, but the assertion was that a cat with a single SD card in its mouth would be higher bandwidth than a station wagon full of tapes. Which is patently not true, even using your calculations.
