The SSD nowadays have a very high write limit, unless you’ll keep writing data on them constantly, you’ll never worn out. You will have to write about 500 times the whole SSD to wear it out (some thousands for enterprise SSDs).

I’ve used about 10 years ago too, but I’ve heard that now it needs a Mikrotik device but I’ve nver had the time to test it

Can it discover non Mikrotik devices?

Why Tailscale AND Headscale? Arent’t they the same thing?
