I'm interested in how you got to the value 250M?
If the unit is meant to be MBytes/s (or MiBytes),... it would mean that the base is 2, this gives 
you speeds of  2^x like 1024 MBytes/s, this divided by 8 gives 128M.


What's the official speed declaration anyone? I also read that for speeds "bit/s" is used (instead of the byte usage like in drbd.conf), but the writing of those units differs also: "gbit/s" in a time/speed context and without the time context "Gbit"?
