Using SSD Drives

You would actually see more benefit loading your OS on the SSD and all of your data (including installed programs and Flight Sim X) on your regular HDD.

If Windows isn't seeing the drive, try going to your start menu and typing this into the search bar (or go to "Run" if you are on XP): compmgmt.msc

You will see Disk Mangement on the left side. Here you can format your SSD. However, I would recommend doing a bit of Googling about SSDs in general before starting to use one. They handle data quite differently than regular HDDs.

you could also get another 60gb drive and put them together in a raid 0 for your OS.

I would spend the money on a single 128GB rather than 2 60GB drives. I'm not sure that a RAID 0 configuration for current SSDs is good for anything except e-peen.
