My understanding is that ASM will also shift data around to avoid the
"hot block" scenario, avoiding I/O contention. It wasn't explicitly

ASM spread extents in proportion to the disk size regardless of the
speed and workload characteristics of the underlying hardware (at
least I never saw the opposite).
See the x$kffxp (ASM instance) for extent allocation map.
