Indeed; I just went ahead and bought PrimoCache. Damn, this program actually works. My system, as I perceive it, is 4 times faster at the tasks that I normally do (no joke). If I had an MB that supported Optane, I would have purchased a 32G optain board since PrimoCache will even allow AMD systems to use Optane. There are cheaper (and similar) programs to PrimoCache, but at $29.95, it ain't breaking the bank and ease of use is a huge factor. I've not really tweaked it yet; pretty much only added L1/L2 cache and a few settings I saw as I was reading about PrimoCache the past 2 weeks. What using the SSD as a cache drive does for me is save me the pain of imaging my original drive. I literally upgraded my system in less than 15 minutes. This is the way to go for an old 6 year old system like I have.
And you Ninja'd me, racer-x.

Yeah, GIMP still takes around 20 to 30 seconds on my system, but I do have a lot of crap that loads along with the GIMP. If I took out user filter and darktable for instance, my bet is GIMP would load in about 3 to 5 seconds too (and when I first installed GIMP before adding all this stuff, it would load within 15 to 20 seconds as opposed to the minute or more it use to take prior to PrimoCache/SSD upgrade; I use to just leave GIMP open since I hated to wait for it to load. lol).
Also, I don't hear my HDD crunch nearly as often now; the sound of silence (well, still have the PC fans; lol).
