Assuming perfect wear leveling such that every page/block is written to once for every 40GB and a write amplification of 1.0 then 1 program/erase cycle for every page/block on the whole drive represents 40 GB. So for a 25nm flash NAND 40 GB drive with a theoretical p/e c. of 3000 then 3000 x 40 GB = 117 TB of data. For a 34nm 40 GB drive it would be 5000 x 40 GB = 195 TB. And for a 50nm 40GB drive it would be 10,000 x 40 GB = 390 TB.
