That’s why you should always use them as jbod and setup Linux software raid (or zfs raid? Not familiar) directly.
Never go without a raid… Not a good idea in any case.
As for heat, I used jbod enclosures with fan, anything with more than 2 drives should have one, or don’t bother.
I wouldn’t go with single drive enclosures (even if I did for 10 years) as better not to cheap out on this matter. A 4 x 10€ cheap enclosure might be tempting, but shilling out 100€ for a nice actively cooled 4-disk jbod is a much better choice. Then go sw raid on top of it.
Has docker compose file for deployment
Can be hosted on sub-path and not only subdomain
