If you're encountering 1 bitflip per year per HDD, something is horrifically wrong.

I've only observed 1 incident of corruption in 5 years of 00+ drives with ZFS, and that was due to a dying HBA controller, not the HDD.

Per year of cold storage.

If the files are overwritten frequently, then the error rate would be much lower. Even if they are only read frequently that would lower dramatically the error rate, because the HDD controller will rewrite the blocks with corrected errors, which happen frequently.

In about 200 TB of high-quality HDDs from 2 vendors and in various capacities, between 0.5 TB and 8 TB per HDD, I have seen around 100 errors after 5 years of cold storage.
