Tlc can easily last more than 5 years for consumer. U are not enterprise user.stop worrying about ssd lifespan. For average user that write 10gb everyday tlc ssd can life up to 20years.so u probably already upgrade new hardware or die.

Any drive no matter hdd or ssd need 10% for better performance. And it wont kill ssd just short lifespans which is still longer than your most pc hardware. Who said cannot download with ssd?

Well my intel died after 3years just after finish warranty while another one still ok after 5 years.there are many factor that coz short ssd lifspan.u just dont know when it will die no matter what nand it use.tlc,slc,mlc,etc

Yup.controller cant stand heat while nand work better when hot but mobo manufacture put heatsink on nand.really topkek
