Ever wondered why most hosting providers take 20% of disk space
Most hosting providers implement disk space limits, often around 20%, to effectively manage the finite physical storage resources of their servers while ensuring reliable performance and fair access for all customers.
Most hosting providers set disk space limits around 20% or similar for their customers mainly due to resource management and fair usage policies. Most hosting providers implement disk space limits, often around 20%, to effectively manage the finite physical storage resources of their servers while ensuring reliable performance and fair access for all customers. This limit stems from several practical, technical, and business considerations. Since many users share the same server disk, hosting companies oversell storage capacity anticipating that not all customers will use their full quota simultaneously.
This practice, known as overselling, allows for more efficient utilization of server space and keeps hosting plans affordable. Providers continuously monitor disk usage and enforce limits to prevent a few accounts from monopolizing storage resources, which could compromise server speed and stability for others. Additionally, disk space is not only about storage volume but also about Input/Output operations per second (IOPS). Excessive storage use can lead to high disk activity, slowing down the server and degrading performance.
Setting disk space caps helps maintain balanced I/O usage. Hosting providers also place limits to prevent misuse, such as using web hosting space to store large media files, backups, or archives unrelated to the hosted website, as this can consume disproportionate resources. Furthermore, hardware costs for storage devices, along with maintenance, electricity, and cooling, contribute to why providers need to control disk space allocation tightly. These policies help ensure sustained quality service across their customer base, prevent abuse, and maintain manageable operational costs.
Reasons for Disk Space Limits
Resource Sharing and Overselling
Hosting providers manage physical server resources among many users. To maximize efficiency and reduce costs, they oversell storage capacity expecting not all users will utilize their full allocation simultaneously. The 20% disk space limit helps prevent a few users from monopolizing server storage and degrading performance for others.
Prevention of Abuse
Providers want to ensure disk space is used primarily for hosting websites, not for purposes like file backups, video or audio hosting, or extensive archiving that could consume excessive space and bandwidth. Restrictions on disk space use prevent customers from abusing hosting resources beyond intended website-related functions.
Cost Control
Disk space requires physical hardware and maintenance costs. Unlimited or very large space offers are often misleading because hosting providers impose limits to keep operational expenses manageable, especially for budget shared hosting plans.
Performance and Fair Use
Limits ensure disk I/O (read/write speed) and overall server performance remain stable by controlling how much storage an individual account can consume. This avoids slowing down the server for other users and maintains quality of service.
GoDaddy recommends that for optimal performance and stability, you should always leave 20% of your maximum disk space free as overhead for system software on their Web Hosting (cPanel) plans. This means if your hosting plan offers, for example, 50 GB of disk space, you should keep at least 10 GB free (20% of 50 GB) to avoid technical problems related to disk usage.
This overhead space is reserved to ensure the system runs smoothly and to prevent issues caused by running out of disk space. If you do not maintain this free space, you may experience degraded performance or errors.
In summary:
| Hosting Plan Disk Space | Recommended Free Overhead Space (20%) |
|---|---|
| 25 GB | 5 GB |
| 50 GB | 10 GB |
| 75 GB | 15 GB |
| 100 GB | 20 GB |
Maintaining this overhead is important for the health and stability of your hosting environment on GoDaddy.
Common Disk Space Practices and Restrictions
- Disk space is generally allocated with clear terms about what content can be stored.
- Usage beyond website assets like HTML, CSS, and scripts often triggers provider intervention.
- Backup files, large media files, and non-website related data may be disallowed or restricted.
- Providers may monitor usage and enforce quotas to keep storage balanced across customers.
Most hosting providers take around 20% or set similar disk space limits to maintain efficient resource allocation, control costs, prevent misuse of hosting resources, and ensure fair service performance for all users. These policies are reflected in the terms of service and fair use agreements that customers must follow to avoid penalties or service interruptions.
