I love my jobs implementation of onedrive. It copies files from my hardrive, erases the local copy, and then loses the remote version.

Those failure rates are nonsense based on theoretical limits. In practice: a few weeks ago I resilvered a 4 disk z1 array with 8tb disks at 85% capacity in less than 24 hours. I scrub the pool every month and it didn’t seem any more taxing than a scrub.
