Linux raid wiki - advice again please

I want to move the old hardware issues page into the archive section,
copying anything of modern relevance into a new page. Unfortunately, I
don't know enough about the issues involved. I strongly suspect,
however, that things like udev have rendered large chunks of the text
obsolete.

https://raid.wiki.kernel.org/index.php/Hardware_issues

The first bit, "drive selection", is an update I did, which I'll be
moving elsewhere.

The section "SATA Configuration" mentions port multipliers, which I know
nothing about. Is this still relevant?

And the bit about "hot swap" - sata, sas, and sca - feels to me like
it's now obsolete because udev will do all that for you - am I right?

I won't be deleting the page, it'll just be tucked away where no-one
will stumble over it and be misled.

Cheers,
Wol
