@Clarity :-
Y'know, there's one corollary to all this increased bandwidth, extra capabilities, etc. D'you know what it is? I didn't figure it out myself until I happened to have reason to re-read the Wikipedia USB article ealier today....
I never twigged it before, but the transfer rate of USB is NOT measured in Megabytes/sec or Gigabytes/sec. No; it is in fact measured in Megabits or Gigabits per second.....and that's not the same thing at all. Puts an entirely different complexion on things.
Remember your basic computer science, kiddiwinks?
.....etc, etc. BUT; what does a single byte consist of?
Answer; yup, that's right. A single 'byte' is composed of eight 'bits', isn't it.....? So.....
It means that for years, folks have been getting ever so slightly "conned". Because whatever the particular standard's claimed rate of raw throughput happens to be, in order to obtain the actual, real-world data throughput you need to divide that figure by 8. And that brings the claimed USB 4.0 40 Gbps throughput right down to just 5 Gbps.....which is what folks thought they were getting with USB 3.0. Me included!
Which does in fact gel quite favourably with the readouts I get from certain newer drives when testing them with DriveSpeed! All this time, I've been thinking there's some kind of horrible bottleneck in my system; as it now stands, many of the readouts are in fact quite respectable, and are well in line with what would be expected, depending on the class/standard they belong to.
Food for thought, huh?
