  >Endurance 400TB = 800 cycles per NAND cell Why not 8000 ? The 850 pro has a 6000 "NAND P/E Cycles"[1] ( P/E = program/erase cycles ) and rated at 300TB ( 512Gb model ) [1] http://www.anandtech.com/print/8239/update-on-samsung-850-pro-endurance-vnand-die-size http://www.anandtech.com/print/8239/update-on-samsung-850-pr...

    doesnt matter as long as you have this hard warranty limit

  Probably a bit less than that depending on how over-provisioned the drive is. But it's not like you'll be able to write 700 times to the same cell deliberately and that value is only the worst case guarantee. If you followed Anandtech's destructive testing most drives last way longer than they're rated for under normal conditions.
