You should defragment your solid-state drive like you do with traditional hard drives to maintain speed.
Defragmentation is a hard drive optimization technique that rearranges file fragments to reduce seek time, a mechanical delay. SSDs access data from anywhere on the chip in nearly identical time, making fragment arrangement irrelevant. More critically, defragmentation writes data repeatedly to the drive, consuming finite write cycles (SSDs endure approximately 3,000–5,000 program/erase cycles per cell before degradation). Running defrag on an SSD accelerates wear-out and reduces useful lifespan without performance benefit. Modern operating systems (Windows 10+, macOS, Linux) recognise SSDs and disable defragmentation automatically; they instead use TRIM commands to optimize the garbage collection process. Performing manual defrag on an SSD is counterproductive and vooids warranties on older drives where the practice might be monitored.
