I am archiving a vast amount of media files that are rarely accessed. I’m writing large sequential files, at peaks of about 100MB/s.

I want to maximise storage space primarily; I have 20x 18TB HDDs.

I’ve been told that large (e.g. 20 disk) vdevs are bad because resilvers will take a very long time, which creates higher risk of pool failure. How bad of an idea is this?

    If you have lots of small files, yes this is bad.

    For videos the space lost will just be a rounding loss.

    Would be interesting to test for music. A 100k 20mbyte files. You could lose a lot of space if using 1 mbyte+ stripes that have been recommended for a while now.
