Nu Kids On The BlocK

[kittensinurface]

Hello, my goal is to replace all bytes on a disk with 0s with a single pass. I have done this many times, but yesterday, I read that I can do it faster with a larger block size 4096. My understanding is, if I use Diskpart or other terminal program to format the entire disk slowly, it will replace all the bytes with 0s.
If I specify a larger block size, such as 4096, 64K, 2M, will it still replace every byte with a 0? Thank you everyone.
