In short, NO. And here's why : Unlimited resources are actually nothing more than a marketing gimmick. In truth the hosting provider will have a large number of other restrictions in place which will prevent you from actually using a very large amount of disk space or hosting resources. Also, we believe that probably you don't even need 'unlimited' disk space or hosting resources. To prove it consider this: a website page size [ even in the worst scenario ] does not measure more than 2 MB in size [ or it should not ]. Take a site with 10 pages. That gives us a website of 20 MB in size. The smallest hosting plans nowadays are way above that capacity. Taking our smallest hosting package as a reference, let's calculate if it's hosting space allowance would meet those requirements:
STORAGE SIZE ÷ AVG PAGE SIZE = # OF PAGES
10 GB = 100000 MB ÷ 2 MB = 50000
Now let's calculate the traffic allowance: Our smallest allowance is 100 GB. So, in order for you to use up that amount [ assuming your site will fall within the parameters above ] you would have to had somewhere near 5000 visitors a month and that each of them, would have accessed every single page of your website. We will use the formula below to prove it.
TRAFFIC ALLOWANCE ÷ SITE SIZE = NUMBER OF VISITORS
10 GB = 100000 MB ÷ 20 MB = 5000
Do this exercise with any hosting plan out there. We used one of ours just as a reference. You should purchase a hosting plan that offers somewhere to 50% more capacity than you currently need or estimate to need it. This will give you room to add more content and handle more traffic spikes when your site really needs it. Anything else is as useless as the 'unlimited' features sales gimmick. Unfortunately for many, a financial waste too.
