The new O&O Defrag 22 Pro is now available and brings groundbreaking new features! The O&O research department has developed a groundbreaking new defragmentation method: SOLID. The new SOLID method from O&O Software is the most resource and hardware-friendly defragmentation method and prolongs the lifespan of both conventional hard disks and SSDs. SSDs store file fragments spread across many blocks, even though much fewer would suffice. This memory behavior has an immediate effect on the performance and lifespan of an SSD. To counteract wear and at the same time to optimize the performance of SSDs, O&O Software has developed the new defragmentation method SOLID. By using the defragmentation method SOLID, these distributed file parts are defragmented so that in the future significantly fewer memory cells have to be read out and also written to when changing a file. As a result, the SSD is faster as the number of read and write accesses is reduced by the defragmentation. In addition, the premature wear of the SSD (and of course the conventional hard drive) is prevented because fewer blocks need to be erased and rewritten than before the defragmentation with SOLID. A positive side-effect of developing the defragmentation method SOLID has been found in tests on classic hard disks: it is O&O Defrags most resource and hardware-friendly defragmentation method ever, with optimal results, and sets the new standard for defragmentation. The new O&O Defrag 22 not only defragments traditional hard disks but also SSDs. As a result, the SSD is faster as the number of read and write accesses is reduced by the defragmentation. In addition, the premature wear of the SSD (and of course the conventional hard drive) is prevented because fewer blocks need to be erased and rewritten than before the defragmentation with SOLID.
