Do you also have numbers for normal SAS/SATA disks? The changelog should
have a reall good explanation of why this is optional, and numbers are a

Yes. I posted the numbers on normal SATA disks a few days ago in the
thread with Sasha. Will add that data and explanation of why optional to
the changelog
