354.69GiB written and reported by Anvil app vs. 354.6975GiB reported by Task Manager. Looks like any discrepancy is at the disk level or not there at all and just showing up due to the way I was measuring.

Going forward, it looks like A) it's totally fine to use Anvil's reported writes and B) SMART values are most likely in GiB.
