Thanks for the info on the internal card readers. I also liked not having extra cables running around.
I am still slightly perplexed on the SSD, one or two? What is the scratch disk? Any advantage two SSD's vs partitioning off a larger drive. FWIW, the PC I ordered has a 2TB internal hard drive, I will likely store photos (after processing) on two external drives.
I replaced my 120GB SSD with a 250 GB one when I moved to Win 10. Since I no longer had a use for the 120GB SSD after that I turned it into a scratch disk for PS instead of using my data drive for that purpose. The SSD is a lot faster for a scratch disk than an HDD, although with 32GB RAM it will rarely see use anyway.
Adobe recommends a fast drive that isn't your boot drive (especially if your boot drive is a HDD) for a scratch disk. They also recommend that you use a different disk than the one housing any large files that you may be editing. If you don't change anything in Photoshop (Edit -> Preferences -> Performance) typically your boot drive will be selected, which isn't a big deal if your boot drive is an SSD with lots of free space.
Honestly, if you have a 250GB or 500GB SSD for your boot drive and if your not RAM limited (you have 16GB or more) and not loading lots of huge files into PS then what you use for a scratch disk isn't going to yield much of a performance boost, if any. For me, I just had a spare SSD doing nothing, so I re-purposed it
