Speed units should be bits/s, not bytes/s 
 
In telecommunication engineering, information transfer rates are indicated using bit/s (kbit/s) units, not bytes/s (kB/s). Byte is information storage unit. 
 
That is the reason why every network interface (host interfaces, switches, routers, ADSL terminals, mobile terminals) show the units in bit/s prefixed with some SI multiplier. That's why your harddrive says giga *bytes*. 
 
Bytes are fine for amount of transferred information or actual storage. Currently comparing your known connection speeds to progress dialog display, it's confusing and inaccurate if you do rough scaling in head (byte == 8bits, /10 --> 20% error).

 And once you've have it on plate, SI unit kilo symbol is small k, not K.
