I just purchased a site yesterday that uses runs Drupal and uses 75 gigs bandwidth a month and gets around 3800 visitors a day.
How many page views? Drupal 4.7/5/6? What modules do you have? Some of the modules can be quite CPU intensive. Also what's the ratio of registered members vs. visitors? Drupal's page cache only works with visitors (although it can be very effective).
In comparison, I have a Drupal (4.7+lots of customised modules) site with around 8,000 visitors a day and 60GB/month on a 360MB Linux VPS, and the 1 minute load avg rarely goes above 0.5.
I thought I'd let you know that I host a Drupal site that gets around 3,800 visitors a day (255,000 page views a month) and I host it on a VPS with 360mb of ram. Everything works great - it does depend on what modules you have enabled though. So let me know some of the details please.
