Do I need to defragment my Intel® Mainstream Solid-State Drives (using Windows* Disk Defragmenter* or similar program)?
No. SSD devices, unlike traditional HDDs, see no performance benefit from traditional HDD defragmentation tools. Using these tools simply adds unnecessary wear to the SSD. It is recommended that you disable any automatic or scheduled defragmentation utilities for your Intel SSD.
