Unlike hard drives, data is written to SSDs in pages - 128 pages equals one data block. Moreover, SSDs use “wear-leveling” to write data across all cells so that they wear out evenly rather than in chunks. Over time, these cells wear out - defragmenting will reduce their overall lifespan. Why? Because data is written to memory cells versus being stored magnetically in tracks on a platter. Running a manual defrag on an SSD can be bad for the drive, too. SSDs can find scattered blocks of data really fast. Files can be fragmented, sure, but you won’t see the performance issues associated with spinning platters and moving heads. There are no mechanical parts that move in search of file bits. SSDs don’t share the same fragmentation problem as hard drives.

This guide will walk you through how to defrag your PC, but before you do, make sure that it’s worth doing. Likewise, Linux-based Chrome OS writes files in an extremely logical manner, requiring very little background defragmentation. Even on computers with hard drives, MacOS and Windows are now more efficient than ever and perform the cleanup in the background. Modern PCs mostly depend on solid-state drives (SSDs), which don’t require or really support old-school defragmentation - indeed, it can actually harm their overall performance and lifespan.
