Sure, raids some drives together, you still have downtime when you switch it off replace the drive switch it on wait for it to rebuild.

Or you can fork out the extra cost to have hot swappable.

If you're saying: "I dont want to pay $300 / month for EC2 instances at AWS when I can get the same hardware specs for $150 at X"

Chances are you're getting a shitty old desktop or barebones rack that lacks features like hot swap and raids.

Do you believe you're getting redundancy when you go with hetzner and a cheap desktop grade processor, ddr4 non ecc memory, and a consumer grade SSD?

There is no extra cost to have hot swappable unless you're considering buying consumer grade hardware, but consumer grade hardware is more expensive to host because it won't fit in 1U bays.

Irrespective of how much I'd skimp on the hardware, I always have a HA setup, including on EC2, so it doesn't matter in any case.

Depending somewhat on the quality of the hardware in question. Hot swap capable isn't rare, but it's not going to happen at the bottom of the price continuum.
