I almost completely agree, but also disagree and yes I'd say it's not worth getting into again. I would have to check the latest developments as I can imagine an algorithm which solved the problem during idle periods or didn't use it's full capacity but currently I don't agree fully with "huge amounts of data". The problem was reduced immensely by spreading writes across all free sectors rather than sequentially but I believe? the problem re-appears on a busy nearly full disk. I would also hope/imagine the only affect would be getting bad sectors in that area but I haven't looked into it very far as I currently have no need to and so maybe I should shut up untill I do. However, I for one will not be treating SSDs like HDDs in all applications of disks untill after I learn more.
