En la wikipedia hay un articulo genial en el que se muestran comparativas de ancho de banda entre distintos dispositivos, protocolos etc.. tanto referente a redes como a dispositivos de hadware, buses etc.
Me he tomado la libertad de copiar y pegar la tabla comparativa en el post que estás leyendo pero podéis encontrarlo de forma integra en éste link a la wikipedia.
Note: All of the bandwidth values listed in this article are true metric quantities, i.e. a kilobit = 1000 bits, NOT 1024 bits; also, a kilobyte = 1000 bytes.
