But since Traffic fluctuates through the day you can't always pull the max out of your Server, so during primetime you'll need the full 10mbps, and during slow hours maybe only 6 mbps. So for an average websites I'd say 10mbps ~2000-2500 GB Data Transfer
That's about right, I'd estimate a little lower.
It depends on a) is that 10Mbps CAPPED or 95th percentile, b) how even your traffic
is - is your busy period twice as busy as your slow time, or three times as busy, and
c) if the bandwidth is capped, how tolerant are you of your server getting slow when
it's busy? If you're capped at 10Mbps, that means you can never go over that. You'll
have busy times and slow times, so you'll want to average about 3Mbps to peak at 10Mbps.
If you average 6Mbps and are capped at 10Mbps, that connection will be overloaded
during your busy time and your site will be slow. Normally, you don't want capped
bandwidth. You want bandwidth billed on 95th percentile - you can use as much as
you want, and you are billed based on "95% of the time you were using less than
XXX Mbps".
