The disk space function shows the total capacity of information that you are able to have on a shared hosting server at any given time. With a home PC, for example, this is the total size of a single hard drive or the overall capacity of all the hard disk drives in the event that your PC has more than just a single one. The same way that the space on a home machine is divided between installed software programs, docs, music files etcetera, the server hdd space is shared between internet site files, databases and emails. Each file, folder or email requires some disk space on the server, and that means you should take into account a lot of factors, not only the size of the files you upload. For example, getting sizable email attachments or having a script-driven website where the user-generated content is located in a database also affects the space you're using.
Disk Space in Shared Hosting
To suit the processing performance behind all our cloud web hosting packages, we have studied and integrated the perfect system for the disk space - your hosting account will not be created using a single server, but on a cluster system. Therefore, what we've designed is an entire cluster of servers that is dedicated to the file storing only, hence you should never be worried about running out of space and having to migrate to a new server since your existing one is unable to accommodate more data. If extra space is necessary, all we have to do is attach more machines to our cluster, so that the hard drive space is practically inexhaustible. Still, all our Linux shared packages are designed to be used for websites, not for an archive of large files. We also have individual machines for the databases and the emails.
