Roaming in 5G is definitely a step up from 4G. I don’t know the exact tech behind it, but the home region profile is replicated while roaming, meaning you get lower latency and faster speeds. In 4G and prior, the user device had to call back home, which would send back the data, and if you’re in another continent it means 200ms+.

Do they have some sort of speed degradation forced by the firmware? I read on Reddit that some of they may have a firmware that slows them down so they will never be as fast as an internal HDD. Did you notice something similar?

My idea was to run it in a mini PC, where I self host some services. I’m not sure if there are HBAs in a small form factor that would allow me to install it on the mini PC (GMKtec G10).

I see some WD Elements external HDDs and they seem to be cheaper than internal HDDs. I don’t know if they’re worth it, though. For example, a 5TB one is about $130.
