I have an Evo 840 for my OS and I put my games on a RAID1 array built from 2, 1TB Western Digital black drives with 64MB of cache. The Windows pagefile and temp directory are on a second RAID1 array with older drives that have 32MB of cache.
I play a lot of Battlefield 4 and I am frequently one of the first players to join the map, even when I am playing on a server with others who have SSD drives.
When I am moving files around my system, I often get ~120MB/s read speed out of the RAID1 array.
While this is obviously not an apples to apples comparison, I am happy to be getting similar performance and more space for considerably less money per gigabyte. I am using the built-in Intel SATA RAID controller.
