I'm building a new web server and am concernced my company's current 1M/Upload isn't going to be able to keep up with the task before us.

I'm expecting 30,000 visitors a month and approxiamtely 1,500 per day and an average upload requirement of 100K per user.

1,500 x 100K = 150Megabytes per day.

150M x 30 days = 4.5Gigs per month.

My current connection affords 950K - 1000K upload and 3.5M download. Should I be concerned and upgrading?

Thanks for your experienced help. The last thing I want to do is invest in the application and server only to find that the bandwidth negates the efforts.
