I've been using O&O Defrag Professional for a few years now and I'm very impressed with its performance. It's easy to set up and use, with a user-friendly interface that makes it simple to select which drives to defragment. The defragmentation process is fast and efficient, and the results are noticeable right away. It also has a great scheduling feature that lets you set up automatic defragmentation sessions, so you don't have to worry about forgetting to run it. Overall, I highly recommend O&O Defrag Professional to anyone looking for an effective and reliable defragmentation tool.

From the developer:
O&O Defrag Professional can defragment your hard disks to improve the file-access speed. When you defragment, the files that Windows splits up when saving documents across the hard disk or SSD are put back in order again so that files can be quickly recognized and found by the SSD or the read and write heads inside your HDD.
