O&O Defrag 25 provides sustainable increased performance, monitors the health and activity status of the PC and so manages to make a big difference in extending the service life of the system itself. Features Analysing a drive’s state of health with S.M.A.R.T.In O&O Defrag 25 the S.M.A.R.T. functionality has been integrated for the very first time. This indicates the “health status” of hard disks, SSDs and RAIDs whenever there is any problem. Such a problem could be a high temperature or an error reported by the drive itself. If there is anything unusual going on, a message will be displayed in the Windows Action Center. New drive activity display in the Windows taskbarIn the new O&O Defrag version, read and write accesses on the computer will be more visible. Users can see the read and write operations currently being run on any drive displayed in the taskbar. A search on the respective drive can be started by right-clicking O&O Defrag supports Windows CompactOSMany new things have been added to the O&O Defrag engine that make using it, especially under Windows 10, even better. That‘s why version 25 now supports the Windows 10-integrated feature for compressing system files so that more space can be kept free. SSD OptimizationThanks to the SOLID/COMPLETE method, data fragments scattered on SSDs will be combined and saved in fewer memory cells. This results in read and write processes requiring fewer accesses to these memory cells in the future. After defragmentation, the SSD works faster and its lifespan is extended because fewer read and write accesses are needed.And as always, everything happens automatically in the background. Even a change from hard disk to SSD will be recognized and the optimization strategy adjusted accordingly.
