the drives in "SSD drives" is unnecessary, it's just SSD, as in Solid State Drive.
I'm still keeping it old school and using a 500gb HDD, and a 1tb ExHDD, they run perfectly fine with photoshop, the program loads in 2.46 seconds with a fair few plugins in there, files as large as 200-250mb might take a little longer to save, but they are certainly within a decent time sensitivity threshold.
I mean, the RAM is good enough, in my opinion, 16gb is plenty for processing large 150mb files, considering even 8gb is more than capable of handling it and with good performance
but SSDs? naah, I'm still struggling to get my head around them, they're great as a boot drive for windows because they can access files quicker, and to some margin they may be more reliable, but programs like photoshop, in all honesty won't see much of a boost in boot up times, save times, yes, but really, it takes a miniscule amount of time to save a 150mb file onto an HDD anyway.
I suppose I'm not one to believe the hypes.
Using an AMD radeon HD7850 GPU in mine, I wouldn't recommend it for super duper graphics intensive stuff, that's where Nvidia comes in, but if it's general filter application with photos, then it'll be okay for that. runs alright with 3ds too.
