>>106010164larger capacity ssd's will last longer than smaller capacity drives. for the simple fact, more space available = increased wear leveling. what kills ssd's is constant writes to the same cells. if you can spread out those writes to other cells, you reduce wear.
when manufacturers list TBW, that's for the entire drive. all cells free for writes.
>4TB nvme has 2400 TBW ratingthat means, for all 4TB free, the cells can withstand 2400 TBW written, erased, written again, X amount of times. If you fill a 4TB nvme to 50%, that leaves 2TB left. You now have the TBW equivalent of 1200 TBW, effectively becoming no different if you bought a 2TB nvme and kept it at 90+ percent capacity free. but if you bought a 2TB nvme, and filled it up to 50%, its effectively now a 600 TBW drive.
Cells with data written to them, are filled, obviously, and thus cannot be written to, resulting in you cannot engage in wear leveling with them. if you want a drive to last, buy the biggest capacity drive you can afford, and don't go above 30% capacity.
also, small file writes kill drives faster than big file writes. its better to write a single, 50gb file than it is thousands of small files that equal 50gb. a single big file, will touch less cells than thousands of small files.
