## difference between 5Mbps Un-Meter, 10Mbps Un-Meter and 400gb

Im still learning when it comes to calculating bandwidth.

can someone give me a rough course on what 5Mbps Un-Meter, 10Mbps Un-Meter and 400gb means and how to calculate bandwidth and stuff like that?

thanks.

i would like to know this too

does the connection (1mps for example) or the transfer per month (300gigs for example) has something to do with the response of the server regarding speed. I mean, does this kind connections would limit the number of concurrent visitors a site may have? For example, if with a 1mps a server can handle at the most 40 concurrent users and with a 10mps can handle 400.,.. does things like this are related in any way or the transfer just means that: the amount of transfer you can use independently of the number of concurrent users and transfer speed.

hope i was clear

regards!

1 Mbps of bandwidth is about 320 GB of actual bandwidth...

Mbps and GB are just different ways of measuring bandwidth usage.

An "Unmetered" 10mbps pipe could push approx. 3200 GB/month, whereas 5Mbps would be half that (1600 GB/month)

Hope this helped you a bit...

This is from a previous thread:

Is this the same : 1Mbps = 1Mbit
1 megabit is an amont of data.
1 megabit per second is an amount of data sent in a second.

Sort of like comparing miles to miles per hour. Got it?

Further more, what is the difference in actual GB of bandwidth and 1 Mbit of bandwidth ?
1 gigabyte = 1000 megabytes
1000 megabytes = 8000 megabits

If I buy additional Mbit of bandwidth is that actual 325 GB of bandwidth. Can someone explain me little more about that.
1 megabit per second = 60 megabits per minute
60 megabits per minute = 3600 megabits per hour
3600 megabits per hour = 86400 megabits per day
86400 megabits per day = 2592000 megabits per month
2592000 megabits per month = 324000 megabytes per month
324000 megabytes per month = 324 gigabytes per month

1megabit per second = 324 gigabytes per month

Now if you really want to get technical will and necessary prefixes, units, 1024's etc, head here:

yes, but if the line is capped at 1 mbps, you probably wont be able to push the full 320gbs. remember, as soon as you peak to 1mbps, packets start getting dropped (not a good thing). peak is usually 1.8 x average useage, hence to push 300gbs without any packet loss you would need at least a 1.5mbps pipe.

In more detail explanation...

Let's begin with the "x mbps unmetered" statement that is plastered all over the hosting industry ads right now... bear in mind that the "unmetered" and "capped" bears the same meaning - which means your server is capped at x mbps... nice way of saying it with the word "unmetered" now but it's quite misleading as well... in short, "unmetered" means you're capped and don't care how much you can push as it will definitely be until x mbps at any one time only...

How does this compare to burstable bandwidth? Like those who offered 400GB a month.... it's a different picture all together... to compare, 400GB is the total (be it actual, average OR 95th percentile - all of which will not be discussed in this post) for the entire month.... like if you're only cruising along till 29th of the month at up to 100GB and suddenly your site got /. 'ed, your site should be able to serve all the demand (depending on your host's network of course) with increased data transfer for the added demand - all until 400GB, in which exceeded, you'll be charged overage by the GB normally...

Back to the unmetered/capped version, even if you're cruising along until 29th (at say around 100GB of actual usage) and then got a huge demand out of the sudden (/. effect or so), unfortunately your server can only push as much as your "x mbps" could allow (which could mean very little during such times) - so the total output that 1mbps can go up to ~ 300GB is very much an inaccurate claim - unless your server is pushing it at constant at 1mbps....

So why 2 different schools? Well... those unmetered/capped is good for those who do not want to incur (or can't afford to - knowing the popularity of some site might get - hefty bandwidth bills aren't pretty) additional overage charges... the downside of this would be packet loss when too many users try to connect at the same time...

As for the other in which they count by total transfers, that way, your server have the ability to burst up the network connections to accomodate a high demand whenever necessary - but additional incurred cost of overage will of course be passed on to you - that way, your users can still access your site - but definitely will help lighten your wallet during /. effects
