Hello All,

We operate a business (video on demand site) that consume lot of bandwidth through storage type servers. Our typical server setup would be

Code:
E3-1230 or  Dual E5 2620 CPU
72GB or more RAM
4x3TB or more storage 
2x1Gbps or 10Gbps (shared unmetered) uplinks
I feel most of these providers are overselling their bandwidth because we are hardly able to push 1.5Gbps from a 10Gbps line.

I would like to get member's suggestions on where I should be looking to get better bandwidth. I do not want to pay super expensive dedicated prices either because we are AD supported.

One option I have in mind is to rent a 10Gbps dedicated line + 5 servers. Another option is to co-locate but I have 0 experience doing that. I even talked to a local Cogent agent for a 10Gbps and he quoted 0.65/Meg which is same as reseller pricing.

Any advice or suggestions regarding this is much appreciated.
Thanks.
