Usually it isn't, exactly because most of the peripherals on the Pi core are connected via USB in the first place. The nature of USB bus is such that packets are not supposed to be lost (or rather, acknowledged as received but dropped on the floor anyway), and some drivers just cannot recover gracefully from such losses. The common end result is a completely locked up kernel, requiring a power reset.

I don't know, largely because I don't care and can't be bothered to find out. It works plenty well enough to meet my expectations for the sort of device it is, the reliability is on par with other similar devices, even some that cost much more, it works far better and is far more reliable than the streaming built into the bluray player I used previously. There is nothing unique about the RPi in this aspect, I do not find it to be any less reliable than similar compact, low power, low cost consumer devices. It is not marketed as mission critical enterprise grade equipment. For applications where I need greater reliability and/or more computing horsepower there are other choices, I use a i7 based mini PC as the Plex server because I needed more power and a real storage subsystem.

Some good points there.
One of the things I experienced was it rebooting when I plugged a USB stick in. Got a digital scope on the board and the 5V rail was dropping to 3.1V when you plugged the stick into it because they cheaped out on supply isolation and decoupling. This of course caused the 3.3V to drop out and the BOD kick off and reboot it :palm: :palm: :palm:.
This is the sort of crap that means it's a toy.

It *is* a toy. It's a $40 computer, nobody is claiming it to be enterprise grade hardware and no reasonable person would expect it to be. It's plenty useful though.

I think you need to read around. Look for the Wallbox and Hypervolt EV chargers - they use a Pi inside! :palm: :palm: :palm: :palm: :palm:

I recall the old adage "If you pay peanuts, you get monkeys" - I'll leave it there.
