I’m glad you understand, we don’t want any learning /s

I doubt they’ll be that stupid, however, all bets are off with the MBA’s back behind the wheel…

Not unless you choose really slow hard drives, or stream very high bitrate media. Most hard drives can easily do 100MB/s sequentially (i.e. reading a large file, such as long video files). Meanwhile high-bitrate 4K video is only about 50Mbit/s, so about 6MB/s.
