July 17, 20196 yr When I bought my Samsung T5 SSD I migrated just my photo scenery over to the new drive, and I saw great improvements in fluidity in the sim as a result---it was fluid prior but way better after the SSD. But I still wondered if I could improve AI performance, which I kept at just half throttle, if I migrated all the rest of the default content, and even the default scenery over to my SSD. I had to first do a straight copy to move my add-ons over, but during the process another background program I was running grabbed all my memory, and some default scenery got corrupted because my migration failed. So I was tired anyway, took a rest, then came back and treated the rest of the process like a P3DV4 upgrade, uninstalling client, content and scenery then reinstalling it and just pointing the client install, which I always install first, to my new "G" drive. I had heard of other various methods to do the process, but they did not seem a clean break that P3D would need to set registry pointers to the new drive location, and the registry does contain a few such pointers for the program. During the process I also cleaned up my cfg file by deleting it and letting it rebuild, so I could ditch any tweaks that I forgot about or perceived as a placebo effect. Anyway, the process completed, I had to do nothing to my add-ons other than re-adding some of my scenery.cfg entries, and that was that. My initial load times are notably faster now by about twice as much with my photoreal textures installed, and it is nice to know that I am not trashing my C drive where Windows resides as much, much better to work with no moving parts to break. My SSD drive did have some integrity errors from my OOM issue early in the process, so I ran a thorough CHKDSK against it which I would suggest anyway before a P3D upgrade, because with so many tens of thousands of files, sometimes things can happen. I also disable write behind caching on my SSD drive, which can cause issues, I try to disable that on all drives as it is well known in WAN admin circles that I came from, that unless you have a UPS, a sudden power loss can result in lost data, especially after a new install of an aircraft or scenery.
