Defrag software optimizes the arrangement of files on a hard disk drive (HDD) to improve read and write speeds. By reorganizing fragmented data into contiguous blocks, it reduces seek time and enhances overall system performance. Many modern defrag tools also include scheduling, SSD optimization modes, and disk health monitoring. While SSDs don’t require traditional defragmentation, defrag software can still perform trimming and optimization tasks for them. These tools are especially valuable for extending the life of HDDs, speeding up boot times, and improving file access efficiency.
