I recently upgraded my home ADSL 2+ internet service (6Mbps) to Optus Cable Broadband (100 Mbps down, 1 Mbps up). The first month I got my bill, I was surprised to see that my data usage had gone up. I used to use about 175 GB per month, and it jumped to about 250 GB per month. Note that Optus charge in both directions, but this did not account for the jump. Not that this is an issue, as I have 300 GB each month. But I started wondering why – it is not like I am watching more Netflix or anything. Then the other night when watch ABC iView on my Blue ray player view the inbuilt app, I worked out what is happening. The internet is soooo fast, that when you fast forward a program, the streaming keeps up – indeed it stays ahead of the fast forward. So in other words, if you are streaming a 300 MB program that runs for 30 mins. After 1 min, you fast forward to the 29th minute mark and watch the last 1 minute, you have actually only watched 2 minutes of TV, but you have downloaded the full 30 mins of video.
Not that this is a major issue, but just wanted to share. If you get faster internet, you may need to purchase more data.
