Why would you do this? You've got extra disks, which means more chance of failure in the first place, and you're not gaining anything. When your OS RAID dies, you'll reinstall it, and find that your games are also not installed, because the new install of Windows isn't aware of their existence. You'll have just as much to reinstall as if you put everything on the Velociraptor. The conventional, and overall best, approach is to use a single fast drive like a Velociraptor for everything you install, including operating system, games, and programs. Then, if you need the extra space, a single large drive for your files. You can occasionally copy your savegames and Application Data folder to the large drive, so when you reinstall you only have to spend a few minutes configuring everything.
I've gone for an even more simple approach: 2x 1Tb F1s... one drive for absolutely everything, and the second for scheduled backups of the 1st drive. Then a mirror is made to an external for redundancy. When it comes to backups... I think simple is best.
Your choice, but as everyone has said... Real world performance you won't notice a difference. Veloci's are expensive enough you could buy two of the F1's and RAID 1 them for redundancy, or RAID 0 them for performance (which would beat the Raptor, just be careful with RAID 0).
yeah that does sounds like it could be the best option for me, a raptor would be nice but I don't think I can really justify the cost of it. I may look into a second F1 as they aren't too much and RAID 0 them and keep good backups thanks for everyone's input
The only exception of this being Steam, and the games purchased on it. You could also point Steam to the games on the second hard drive, but the games may not load properly due to some files missing that were with the game install on the first hard drive.
