What's new in this version:

- 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. To stay with our example above: To read our sample file, it is not necessary to first access and read 32 different blocks, but only a single one.
