Anyone know the NAND chip config for all these devices ? So if 256 is two 128 on the M1 Air, does that mean 512 is 4x128 or 2x256 ? Etc..

That's the issue - two spots, but instead of maintaining a 128GB part for 2x128, they're shipping 256 as 1x256.

I can see the logic, they're not maintaining a whole part/inventory just for the lowest config. I'll let everyone else argue over whether it's worth the penalty or not.

The 512 is 2x256. I'm pretty sure the Air line only has two spots for NAND flash.
