You can label your devices. When formatting, do mkfs.ext4 -l my-descriptive-name /dev/whatever. Now, refer to it exclusively by /dev/disk/by-label/my-descriptive-name. Much harder to mix up home and swap than sdc2 and sdc3 (or, for that matter, two UUIDs).

First, why is every post on this forum -1? Somebody must be holding a grudge.

Second: it doesn’t matter. ECC just prevents bit flips in RAM, once data leaves a system it’s irrelevant whether it had ECC or not.

I’ve been running servers of various kinds for decades. There is a difference between running servers on hardware with ECC vs none, but it’s not a big deal. Unless you’re running, like, banking software or something where accuracy or uptime is critical…I wouldn’t sweat it. You may just have to reboot cuz of a kernel panic once or twice a year.
