Send Your Feedback for Advanced SystemCare 8 in OFFERS! Posted August 29, 2014 For any & all requesting information regarding optimizing/defragging a SSD. These drives do NOT need to be defragged as you are actually doing more harm than good by doing so. By design, SSD's install information in a "fragmented" way. However, each nand cell can be read/written to, so even though the information is "fragmented", it will still read much faster than a HDD. For this reason you should not "defrag" a SSD. It is meant to be fragmented. Forcing an SSD to defrag would make it continuously read/write and move the data pointlessly, basically lowering the lifespan of the SSD. Far as I know Iobit does not defrag SSD, SSD optimization is a specific technique and does not short SSD life or affect data.
