Yes, Win7 x64 Professional. I am using a Samsung 840 (128GB) for the pagefile disk. I have been putting pagefile.sys (and TEMP, TMP) on a separate disk since NT 4.0. I have not run any benchmarks on Windows 7 to see what the improvement is like.
If you are curious about the impact of the pagefile on the OS drive, I would look at disk queue depth and file latency. As long as your queue depth isn't over 2 and your file latency stays in 5-10ms range, you should be fine.
Before I went SSD on the data drive, I was running 7200 SATA drives in RAID1. The write penalty kind of sucked, but having two spindles for reads was nice. The benefit only really showed up during sustained reads, like loading new levels in various games.
To be completely honest, as soon as the system starts hitting the pagefile with any sort of regularity, you need to buy more RAM. Tuning the disk subsystem is not going to get you much benefit. For example with WatchDogs, I started playing it with 6GB of RAM. That was not enough, and the OS was paging at 16MB/s. That was just too much IO, even with a dedicated drive. The drive itself can handle way more than 16MB/s, but the application could not deal with the latency of having to go to disk.
