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 the button Configure.
- 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 are not able to perform SSD TRIM on RAID 5 and RAID 6 volumes. Please refer to the compatibility list at www.synology.com.
- SSD TRIM cannot be enabled in the following situations:
- The volume is mounted with SSD cache.
- The Time Backup package is installed.
- SSD TRIM cannot be enabled on Block-Level iSCSI LUNs.
- 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 disk group or RAID group.
