Can Any One Tell Me How Much Bandwidth (in GBs) can a 256k Dedicated Connection Give ?

Some One Told me that it can give upto 80.4 GB !
Is That Correct ?

Can-Host.com has a good chart :

128Kbps = ~40 gigabytes/month
256Kbps = ~81 gigabytes/month
512Kbps = ~162 gigabytes/month
768Kpbs = ~243 gigabytes/month
1Mbps = ~316 gigabytes/month
t1 at 1.544Mbps = ~488 gigabytes/month
t3 at 45Mbps = ~14,238 gigabytes/month
oc-3 at 155Mbps = ~49,049 gigabytes/month

I figure you are getting numbers for either co-lo'ing or something so just remember that sure 80 gigs might sound like a lot but the really important thing isn't amount you can trasfer in a month but amount of traffic you can handle at one time. 256kilobit is only like 32kilobytes/sec which isn't much for a heavily accesses site. get 4-5 modem uses downloading a large file and you're going to be maxed out...

Exactly, 50GB fully burstable is better than 80GB like this in my opinion.
