These locally show the expected O(d(n)) growth of the block_size search when block_count is known. A rough estimate of runtime for a 1 GiB device with a 90 MiB/s read bandwidth (using the mt25q for rough numbers): known bs/bc => ~1.44 us known block_size => ~1.44 us known block_count => ~125 us unknown bs/bc => ~376 ms
