Also, I have two external Samsung 850 Pro 512 gig SSDs inside nice, slim Orico enclosures. As I mentioned, both of my Macs have internal SSDs, so when I did the clean, fresh installation of High Sierra, it automatically formatted each of them as APFS. What happens is that if you have any kind of flash storage inside your Mac onto which you are installing High Sierra, High Sierra will automatically format it as APFS. To add to what Cory stated, for myself, the new file system, APFS, has been OK. But I am getting more and more used to High Sierra, but again (at least for me), it has nothing earth shattering that is different from Sierra. Sierra is definitely a stable OS, and in some ways, I wish I was back on it.

I also do not see anything drastically different and/or improved from Sierra, so unless you see a compelling reason to upgrade to High Sierra (like a new feature), it might be wise to upgrade to Sierra. High Sierra is somewhat slower than Sierra, mainly in booting up, switching start up devices, switching to Tech Tool, Pro's eDrive, and then back from any of those sources to the internal SSD, and shutting down.

I have also done the upgrade from one Mac OS to another via a clean, fresh, "virgin" installation of the new OS. I have always updated to the new Mac OS each time, although I wait until all of my third party applications are compatible with the new OS (and I have 6 critical ones that must be compatible). Also, I have well over 60% of free space on each of those SSDs (and I do not do much "serious" processing with either machine, especially in comparison to you).

I make a concerted effort to keep my Macs "lean, mean, and clean", and in actuality, I am performing disk cleanup on my own just about every day (mainly having deleted EMails permanently removed). Now, as far as High Sierra is concerned, I have two Macs: a late 2012 Mac Mini with a 256 gig SSD and 8 gig of memory, and a mid 2017 13" MacBook Air, with a 252 gig SSD and 8 gig of memory. How much free space is on your internal SSD? Two that I use (and have been using for along time) are Onyx, and Tech Tool Pro.

Have you done any "extensive" disk cleanup/maintenance/repairs, from a software perspective? You actually can do a good amount of disk cleanup on your own, and there are some excellent programs available (both free and commercial) that can help you out. I guess a couple of things to look for/mention:ġ. Kind of surprised you are experiencing slow downs, as I believe your machine has 512 gig of flash storage, along with plenty of memory.
