Current generation (consumer-grade) MLC SSDs using 25nm technology use
flash that can only be rewritten 3000 times. Assuming perfect wear
levelling, that's still enough for most desktop applications.
120GB*3000=360TB.  That's still almost 100GB per day for ten years. Even
if write amplification quintuples the amount of date written, that's
still 20GB per day. My systems don't write that much.
