Many web hosting plans available today claim to offer unlimited space and data transfer (also known as bandwidth), but in reality? In a word, yes.
Back to the early days of web hosting, hard drives were relatively small and the bandwidth was expensive hosting company to buy. Therefore, they put strict limits on the amount of such funds that each customer can use each month. But in today’s world is a huge hard drives are the norm, and the bandwidth is much cheaper, thanks to upgrades Internet infrastructure backbone.
This is good news, because now you have a host so many pages, files, images, and how they want without any restrictions. There is a warning, though. The number of site location to put the server is not unlimited. If you’re really busy site, which makes extensive use of databases and / or server-side processing, it brings a common server to his knees in a hurry, maybe even cause it to crash during peak hours.
I can accommodate a number of websites in an “Account Reseller, for all practical purposes is simply a collection of sites that run on a shared server. My sites all run very well, although several of them quite large and getting a lot of traffic.
So even if the disk space and bandwidth is indeed infinite, you should still keep an eye on how much CPU and memory for the site to consume and to consider upgrading, either VPS or dedicated server at the appropriate time. Until then just enjoy cheap shared web hosting plan. You can always upgrade later, if necessary.
