Hi,

Can somebody explain me what 28.3 Mbps means ? I thought it meant an average (or is it maximum ?) 28.3 Mega bits per seconds encoding rate. If this were true then my calculations don't make sense :

a) 28,3 Mbps * 60 = 1698 Mbpm * 60 = 101880 Mbph / 8 = 12735 MBph
b) 160 GB * 1024 = 163840 MB / 12735 MBph = 12,87 h
c) 250 GB * 1024 = 256000 MB / 12735 MBph = 20,10 h

=> 12,87 hours is not in the range of 17-24 hours (160 GB)
=> 20,10 hours is not in the range of 26-65 hours (250 GB)

I asume the 'b' in 28.3 Mbps stands for 'bits', the 'b' in 160 Gb stands for 'bytes' (?)

Can somebody explain me where I go wrong ?

Thanx

Mbps = megabits per second

Mb/sec, Mbits/sec, Mb/s or Mbps means megabits per second and is used for transmission speeds in a network or in internal circuits.
