Nothing wrong with 8%, it's amazing what improved equipment can do isn't it. Glad you're happy, you'll be ready for the new version now too.
Skuzzy has made specific mention regarding the frequent small read/writes AH does, and how that may not be all that great for your SSD drives. I've got an older one, my first Samsung 830 128gb drive, which I don't care about frying, and I run AH on that, but otherwise I'd do the same as you and run it on a regular spinner drive. More than fast enough IMO. Boot times from a spinner drive to SSD when set up for a fast boot is pretty shocking the first time you see it. I just saw Win10 booted from a new Samsung m.2 950 on Monday this week - about the same jump in speed again, wow.
