> There are only a few fabrication plants in the world that make nand at the current node sizes. That comment kind of assumes that making NAND as small as possible at the silicon feature level is desirable. That's not necessarily the case - in some cases, data retention is preferable to storage density. Larger feature sizes make NAND much less susceptible to retention failures and read/program disturb failures that are no big deal in SSDs, but are a huge deal in embedded applications.
