More NAND dies means a given number of TB of writes will require doing fewer write/erase cycles per memory cell, because you have more memory cells.
NAND flash almost never fails a whole die at a time. An individual NAND die fresh out of the fab will already have a few defective memory cells, and as the drive is used, more write cycles will result in more memory cells failing and being retired. This gradual, partial failure is fundamental to how SSDs manage flash memory.
