That is, 16 TB drive is guaranteed not to return the data written to it in the first pass, right?

In other words, if one has raid-5 like array of such drives, an unrecoverable error will appear for sure during the array rebuild process? That’s sweet!

ZFS raid-z2 / raid-z3 or LizardFS ec(x,2+) to the rescue?
