Over-provisioning is a practice to exclude a certain size of the SSD capacity from use to prolong its life expectancy and performance.
If you are using a Samsung SSD, you are in luck because they already provided a free tool that allows you to enable over-provisioning easily.
In this guide, I will show you how to enable over provisioning using Samsung Magician software. Mine is Samsung 860 EVO but this tool should gonna work on any Samsung SSDs.
1. Download Samsung Magician and install it on your computer. Note that the download button located at the bottom of the page.
2. Launch the program, then go to Over Provisioning menu.
3. Set the amount you want to allocate. Ideally is 10% but the higher the better. Then, click Set OP.
4. Wait until the process finished.
5. Now the over provisioning has enabled.
In my case, I have 465 GB in total usage capacity. But, since I have allocated 10% of them which is around 46 GB, now I only have 418 GB left to use.
But hey, my SSD will last longer with the highest performance.
But don’t feel bad about it. In fact, SSD manufacturers encourage people to enable this feature and try to leave as many free spaces as possible. This is a very good video explaining over-provisioning — you definitely have to check it out!

Additional Tips for Over-Provisioning Your SSD
Manual Over-Provisioning Without Samsung Magician
If you’re unable to use Samsung Magician or prefer a manual approach, you can still set up over-provisioning during the initial setup of your SSD. Here’s how:
- Partition the Drive: Use your operating system’s disk management tool to create a partition that leaves a portion of the SSD unallocated. For example, if you have a 1TB SSD, leave 10% (approximately 100GB) unallocated.
- Avoid Writing to the Reserved Space: The unallocated space will automatically function as over-provisioning, allowing the SSD controller to utilize it for wear leveling and garbage collection.
This method works well for users who want flexibility or are using non-Samsung SSDs.
Troubleshooting Common Issues
- If over-provisioning is greyed out in Samsung Magician, ensure there’s sufficient free space on your drive. You may need to delete unnecessary files or partitions to free up space.
- Encountering multiple over-provisioning partitions? This could be due to a software bug or leftover recovery partitions. Use tools like Disk Management or Diskpart to carefully remove redundant partitions.
Benefits of Higher Over-Provisioning
While 10% is often recommended, increasing this percentage can provide additional benefits for heavy workloads like video editing or gaming. Drives with higher over-provisioning ratios tend to maintain performance and reliability even under intensive usage.
FAQ
What happens if I don’t enable over-provisioning?
Without over-provisioning, your SSD may experience reduced performance and lifespan as it fills up. Tasks like garbage collection and wear leveling become less efficient, leading to slower write speeds and potential data integrity issues.
Can I change the over-provisioning percentage later?
Yes, you can adjust the over-provisioning percentage using Samsung Magician or by manually resizing partitions. However, any changes will require freeing up space on the drive.
Is over-provisioning necessary if my SSD has plenty of free space?
Even with ample free space, dedicated over-provisioning ensures consistent performance and better wear leveling. It’s particularly useful for maintaining speed and reliability as the drive ages.
Do all SSDs support over-provisioning?
Most modern SSDs support over-provisioning either natively or through manufacturer software. If your SSD lacks specific tools, you can manually reserve unallocated space during setup.
