Do I need to defrag my SSD or flash drive?

No. Unlike a traditional hard drive, an SSD (solid-state drive), jump drive, flash drive, and thumb drive have no moving parts. Which means even if you were to defragment the drive, it wouldn't increase the performance of the drive. Defragging arranges data on the drive into one section so the access arm can get to it faster, instead of having to access different sections of the drive.


Defragging a flash drive is considered a bad practice as it can decrease the life span of the drive. Each time data is written to the drive, the flash memory is degraded, and defragging is an action of writing data to the drive.
