When searching for a web hosting provider you may be compelled to choose the host offering unlimited bandwidth or unlimited storage. Of course there is no way to physically guarantee this. What the provider is saying is that you can use as much data transfer (unlimited bandwidth) or as much disk space (unlimited storage) as you require. The majority of websites use less than 100 megs of disk space and less than 5 gigs of data transfer. If your site is one of the very few that uses a lot of bandwidth or disk space you will need an advanced hosting or dedicated hosting solution. However, be wary of the providers offering unlimited storage of bandwidth. Often these are ploys to lure customers into purchasing plans. If your website requires a lot of disk space or bandwidth, it will also likely require a lot of server resources (cpu and ram). Some unscrupulous hosting providers will terminate your account if you use too much of their server resources (because they are losing money with your account). So they still allow you unlimited storage and bandwidth, but they terminate you for using too much of their server resources! There also may be restrictions on the types of files that you may host such as no video or audio files permitted. If you know your site will have heavy traffic or require lots of storage space you would be better served finding a limited plan with the high bandwidth or storage you require.

The most important criteria for choosing a web host should be their level of technical support and reliability of all their hardware and software resources. After all, all the disk space and data transfer in the world is meaningless if surfers can’t access your website. The moral of the story: If something seems too good to be true – it is.

Conclusion
Don’t choose a hosting plan solely because it includes unlimited storage or unlimited bandwidth. Choose a plan from an experienced, reliable, and reputable provider. There are many hosting plans offering high bandwidth and high storage limits. If you know your site will require a ton of bandwidth or storage, don't expect problem free hosting with a low-priced, unlimited plan. Don’t be fooled by sales guarantees that get you in the front door. More often than not, you get what you pay for.
