Defragging an SSD is often a good thing? Why? It would seem to greatly increase wear for no benefit.
- akvadrako 8y agoIf your fragments are really small like 16kb then you could see a significant performance improvement, due to better predictive loading and packet overhead. This is clear from SSD benchmarks. But I don’t see how this would ever realistically happen.
- forapurpose 8y agoWhat about the massive effect on wear?
- tinus_hn 8y agoYou don’t know if there is wear. The controller is a separate computer. It may be clever and just remap blocks if you copy or move them around. It could be that defragmentation allows the system to work in a way that is better for the controller or allows that controller to place the blocks in a better way.
