Optimize SSD and Defrag Hard Drives from Command Prompt

Unlike HDDs, SSDs do not benefit from defragmentation and, in fact, it can even be detrimental. This section explains why defragmenting an SSD is not only unnecessary but could potentially shorten its lifespan. File fragmentation occurs when files are sto

Don’t defrag your SSD —it has no impact on SSD performance. ???? Defragmentation can shorten SSD lifespan —each defrag operation counts toward an SSD’s finite write cycle.

The short answer is no: you don't need to defrag an SSD. SSDs are designed to access file fragments without delay using flash memory, with an average seek time in the region of 0.1ms.

In this guide from EaseUS Software, we'll explain what defragmentation does, why SSD drives and defragmentation don't mix, how the TRIM command works, and the safest way to restore SSD performance. What Does Defragmenting Do "Do you need to d

Defragmentation is not recommended for SSDs because it can potentially decrease the performance and lifespan of the drive. This is because SSDs have a limited number of write cycles, and defragmentation can use up a significant portion of these cycles, re

On the contrary, if you defrag SSD, it will cause unnecessary wear, as defragmentation requires frequent data movement, resulting in a large number of unnecessary erase/write operations, accelerating wear on SSD and shortening its lifespan.
