What if the health status of SSD is not 100%?

Normal, generally speaking, health is closely related to the life of SSD. Although 100% is not accurate, it has certain reference value. I checked this PCIe4.0SSD, which has a five-year warranty, but only 400TBW. Another Lei Kesha PCIe4.0SSD also has a five-year warranty of 500TBW. But how can I put it? These two TBW are quite few. In fact, TBW is the value used by the manufacturer to define the warranty period, that is, after the written amount of this value exceeds, the manufacturer will no longer provide warranty service.
