Amount of time to transmit 5GB to USB 2.0?

-3

How many minutes should it take to transmit 5GB over a USB2.0 (assume 500 Mbps) bandwidth connection? How would I figure this out??? When I did the math I came up with 1.3 minutes which Im pretty sure is incorrect. Here is what I did:

5*8000 = 500*60*x

40000=30000x

X = 1.3 Minutes

It should come out to ~1 minute and 21 seconds (+- 1 second).

to do this:

500 / 8 //calculate the MBps. 8Mbps to a MBps.
= 62.5

5 * 1024 //calculate what 5GB is in MB
= 5120

5120 / 62.5 //calculate the final seconds amount
= 81.92

Hmm. I get 85.9s from http://www.dslreports.com/calculator?sz=5GB&time=&c2=Calc&speed=500Mbps

@DavidPostill I did this on paper. my answer could be a little out. just stating what I did – td512 – 2016-01-12T23:56:45.650

I guessed you worked it out by hand. I'm trying to work out which one is correct ;) – DavidPostill – 2016-01-12T23:57:32.383

I too get 81.92s ! – RogUE – 2016-01-13T00:06:16.557

@RogUE thank god I'm not the only one to get the same calculation – td512 – 2016-01-13T00:09:21.727

500 Mbps = 59.6 MBps according to dslreports. There is the discrepancy. – DavidPostill – 2016-01-13T00:10:40.940

@DavidPostill I thought 1 MB = 8 Mb... they must've done something wrong – td512 – 2016-01-13T00:12:01.343

Isn't 8Mbit=1Mbyte, @DavidPostill that means 1MByte=8.3892Mbit
