I've seen it mentioned here that generally data extents are 1G and
metadata extents are 256M.
Is that per-drive or per-stripe in the case of RAID0?
That is, if I have data mode raid0 across N drives does the system
allocate one 1G extent on each drive making the full stripe allocation

Based on looking at how identically sized, empty, qcow2 files grow
when they're added to a Btrfs volume, the 1GiB Btrfs chunk or
allocation unit, doesn't have an immediate physical allocation. It's
more of a virtual thing, but it has a physical manifestation.
