SSD TRIM
If a volume consists entirely of SSDs (Solid State Drives), we recommend enabling SSD TRIM. This feature improves the read and write performance of volumes created on SSDs, increasing efficiency as well as extending the lifetime of your SSDs.
To enable SSD TRIM:
- Open Storage Manager and go to Volume.
- Select a volume that consists entirely of SSDs, and then click Configure from the Action drop-down menu.
- In the window that appears, go to the SSD TRIM tab, and check the box Enable TRIM.
- Click the button Set schedule to choose when the system will perform SSD TRIM.
- Click OK.
Note:
- SSD TRIM is only available on certain DiskStation models and RAID types.
- Some SSD models do not support performing SSD TRIM on RAID 5 and RAID 6 volumes. To check if your SSD models support SSD TRIM, please refer to the Synology Products Compatibility List. You can search your SSD models on the page and click the Note field to check detailed information. Unsupported functions, including SSD TRIM, will be listed in Note.
- Configurations that do not support SSD TRIM include the following:
- The RAID type of the selected volume is RAID 0.
- SSD cache is mounted on the selected volume.
- LUNs are created on the selected volume.
- System performance will be affected when performing SSD TRIM. The time needed to finish performing TRIM varies depending on volume size and SSD model.
- When TRIM is enabled on a volume, it will also be enabled on other volumes created on the same storage pool.
