In order to actually use that kind of space and be within limitations of the fine print, you would need a static HTML site with virtually no scripting, no movies, no MP3s or other large files. Considering a typical web pages is about 50KB in size, and a “web hosting gigabyte” is equivalent to 1,000,000 KB, you’d have to build 20,000 web pages to use just one gigabyte of disk space! To consume all 250 gigs of space, you would be writing 5,000,000 (5 million) web pages.
To put it into perspective, if you were to simply count out loud (yep, people would think you were strange, I don’t suggest it) to 5 million, at the rate of 1 number per second, it would take you 83,333 minutes, which is equivalent to 1,389 hours, or roughly 59 days!!!
