[QUOTE="Randy B. Singer, post: 1851809, member: 190607"] I forget where I was where there was just an entire in-depth discussion on this. The thing is, as you know, that each block of an SSD is only good for a certain number of reads and writes. Somewhere around 8. Wear leveling holds off blocks from dying as long as possible by making sure that all blocks on the drive are used equally. As blocks finally wear out and die, new ones are substituted for the dead ones. An SSD usually has a higher capacity than the rated capacity, to provide more blocks for just this purpose. This is called over-provisioning. The thing is, there isn't as much over-provisioning now, on newer, cheaper SSD's. So, once blocks start dying, blocks from less used portions of the drive are used instead, as part of the wear-leveling process. But as you fill up an SSD more and more, there are fewer and fewer spare blocks available, and your drive gets closer and closer to being full, even though your SSD would seem to have a lot of it's rated capacity left. So it's not due to fragmentation at all. And if your drive is fairly new, sure, you can fill it up all the way to 100% full and it will be fine. But the combination of time and filling your drive up too much will lead to your drive being full with a lot of drive capacity seemingly still available. This is going to come as a bit of really bad news, but as the price of SSD's comes down, they are becoming less and less reliable, and they are also becoming slower and slower. The latter is because another cost cutting measure is to entirely leave the DRAM out of SSD's. See: [url=https://www.youtube.com/watch?v=ybIXsrLCgdM]YouTube[/url] [/QUOTE]
