I’m having trouble finding the blue where I live, so I think I’ll go with the Red Plus 8TB, WD80EFZZ…is it helium or air?

Thanks! So I’m finally going with the wd blue 6tb cmr:

Is it helium?

Thanks. How about the corruption issue on smr?

Thanks! It’s 3.5. Where does it say whether a disc is CMR/SMR/Helium?
