To fill in one piece of information, I'm reading the maximum block size can be
limited by the Linux page size, 4K on x86. Is this true in ext4?
I know this is a basic question, so thanks for humoring me.

Generally, yes.
There are patches:
ftp://ftp.kernel.org/pub/linux/kernel/people/christoph/largeblocksize/4/patches/
but I'm not sure what the current state of all that is, honestly...
Before it's discussed as a limitation though it'd be interesting to see
some recent benchmarks on how much it might actually matter.

it may indeed help.
