The disk space feature displays the full amount of data that you can have on the shared hosting server at one time. With a home PC, for example, this would be the total size of your hdd or the full size of all of the hard disk drives in the event that your PC has more than just a single one. Exactly as your space on a PC is divided between installed computer software, documents, music files etcetera, the server hdd space is ordinarily divided between website files, databases and email messages. Every single file, folder or email message requires some disk space on your server, therefore you should take into consideration plenty of factors, not only the size of the files that you upload. For example, receiving sizeable e-mail attachments or having a script-driven site in which the user-generated information is stored in a database will also affect the space you're using.
Disk Space in Shared Hosting
To match the processing power behind our cloud web hosting packages, we've studied and integrated the best possible option regarding the disk space - your account is not made using one server, but using a cluster system. Because of this, what we have built is a whole cluster of servers that is centered on the file storage only, so that you should never be worried about not having enough hard disk space and having to switch to some additional server because your current one can't accommodate more data. Whenever extra space is necessary, we add extra machines to the cluster, so that the hard drive space is inexhaustible. Needless to say, all our Linux shared hosting were made to be used for web sites, not for a repository of big files. We also have individual machines for the databases and the email messages.
