I do remember *years* ago, when the ZX Spectrum was a current machine,
that one software house (Codemasters, possibly) released games on CD.
The improvement in bandwidth and speed stability allowed them to write
really really fast speedloaders. With cassette, as the data rate went
up reliability went down.
Of course the Spectrum used a weird 1800bps-ish format - each bit was
two cycles of the appropriate frequency, with zeros being 2400Hz and
ones being 1200Hz. So, for average data it came out about even, but
long sequences of zeros went past quickly. I tried writing a four-tone
tape routine with two bits per symbol, with variable degrees of success.
