Brand new nvme drive already reads 73% health

where did you buy it? if it's a marketplace seller rather than the brand or a big shop, that's usually the answer. most makers can look up the serial and tell you if it's a return, worth an email before you load your stuff onto it.

Look at the raw numbers instead of the health percentage. CrystalDiskInfo or the manufacturer's own app will show total host writes, power-on hours and available spare. If writes and hours are both near zero, the tool is misreading the drive. Some read the wrong attribute on certain controllers, so check it in the maker's app. If the drive shows lots of data already written, it's used or refurbished stock sold as new and I'd send it back. Same if available spare is already low or it logs media errors.
