Disk Space
Disk Space is the amount of space you're given to store your files. The common misperception is that you need all the space being offered and so should always go with the host that offers the most. This is not necessarily true.
A small static website typical for many small businesses really doesn't need a lot of space. Let's assume your site is 100 pages and that each page has a file size of 100KB. Further let's assume each of your pages has another 100 KB of images for a total of 200 KB per page.
100 pages at 200 KB each is approximately 20 MB of space. So does it really matter much if you purchase a hosting plan that comes with 5 GB space or 10 GB space? You could fill 5 GB with about 250 copies of each of your files.
It's still a good idea to get more space than you currently need, but having 500 times as much space as you need isn't a much better deal than having 250 times the space you need.
