Are you really going to notice a 12% faster load time from something that loads in just a couple of seconds?
Only you can say how much you need to install onto your SSD. I have Windows, Productivity Apps, the Steam and UbiSoft Apps (apps on C: games on D
and one other game on my SSD. My 500GB SSD is only 1/4 full. I'm not a huge game player, but I don't notice any issues with having my Steam games stored on my HDD.
I think you could get by with putting your most popular games on a 1TB SSD and your less frequently played games onto your HDD.
Not sure if it would help, but I'd also consider just making a logical drive/partition on your large HDD just for your games. Maybe a 1.5TB D: drive for your games, I would think that would limit the amount of hard drive space your system needs to read when attempting to access your game files; searching a 1.5TB partition as opposed to a full 6TB drive. Again, not sure if it would actually help,
