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.
