It is nothing we can fix. It is an inherent issue with how SSD's cannot update files. Once data is written it cannot be directly altered. It is a very clumsy thing the SSD's go through, when a file needs to be updated.
They actually have to make a copy of the original file into a RAM disk (yes, they take a chunk of your system RAM away for that), then when the file is updated, they copy the file to a temp name on the SSD, then remove the original file, then rename the temp file. During this convoluted process, the file is locked which means no further updates can be done until it is complete.
So for each block of data changed in a file it has to go through this dance. For any given file, a patch can do this hundreds of times. There are firmware issues with some SSD's which cause the errors to happen. There is also a timeout issue which can cause problems when patching large files. None of this is in our control.
Well, actually, we can fix it and do what most other games do. Not patch at all, just ship the entire file that needs to be updated. It would make patches huge. Matter of fact, in many patch cases, it would be the complete game. So instead of a 100K patch, it would be 1.9GB.
