Hello, my question is: is there big difderwnce in making m.2 nvme disk with storage of 250gb instead of 1TB or more? Maybe it is stupid question. Is there physical difference?

More nand flash chips means more cost. Those chips are the highest cost in the BOM, so if a customer only needs 250GB, having a product for them means a sale instead of not a sale.

A drive with one of these:

Would have $14.48 of nand chips.

A drive with four of them would have $57.92 of nand chips.
