Should I split a big (8TB) backup disk into more than one partition, or not?

[Joel Rees]

What on earth are you going to fill an 8T backup drive with?

Okay, I shouldn't say "what on earth", because that is going to induce
distracting responses.

Whether you need partitions, soft RAID (single drive striping), hard
RAID (well, since you've only bought one drive, we assume not), or
something yet else, depends on what you plan on filling that 8T drive
with.
