From personal experience, the Chromecast 4K on its is very limited on free space. That means if you want to install more than a handful of apps, you will need to resort to a USB hub, most likely a powered one, to connect a USB flash drive or SD card in order to expand the usable space.

If you think that’s not a problem, the Chromecast is a very capable device. I won’t put it on the same level of performance like an Apple TV 4K, but it can do everything I throw at it, albeit in some slowness from the UI from time to time.

TIL and that was a great story, but I think you mixed up the roaches!
