Load times will more than likely be marginal. With a SATA III Samsung SSD your speed is going to be blazing fast. Adding RAID 0 to the mix isn't going to show much more gain IMO. The levels should zip right along with a normal SSD without RAID. RAID 0 with two SSDs is just for bragging rights. Also, you will not have 2 TBs with RAID 0 or RAID 1. They will both act like one drive of 1 TB only. So if you want 2 TBs, buy two 1 TB drives. When one drive fills up use the other as spill over. Just install the game to that second drive. I did this with mods. I had three to four versions of COD Modern Warfare. One version was updated to the latest, the other was a different version and another two had different Mods. All I did was copy the game from programs folder to the second drive in its own folder with its own name. Like; COD 2.0, COD 4.0, COD Zombie mod, etc. If you want redundancy to make sure if one drive messes up you have a backup, then by all means use RAID 1. That's a mirrored array and thus you'll have a copy of everything on both drives. If one drive goes you have the other with an exact backup. But like I said, you'll only have 1 TB to play with. Now if you bought SATA III platter drives, then perhaps a RAID array would be a little more beneficial for speed. Even then, probably not by much except the drive speed numbers. Hardly noticeable. I mean, I have a Crucial MX300 SSD and it's around 500 MB/s, yet BF2 with my AIX mod doesn't load any faster than a platter would. I even have my doubts if it would load faster in a RAM drive. Yet I'm running a i5 6600K with a GTX 1050TI.
