One can do a test of an HDD, it won't be a compare though.
It would still tell for how long (that particular) HDD would handle the stress of this test, it might go on for years or it might fail in a few weeks, as the HDD has moving parts there are other factors that could trigger a failure.

I'd say it's an interesting test to do.
I'm running a short test as we speak on an F3, looks like 8-10TiB/day is doable on an empty drive, mine is half full and avg speed is 98-99MiB/s. (one loop is set to ~12GiB of writes)
