Raid vs single drive

[shrap1968]

OK, after reading all of your posts, i am seriously confused. There are some interesting arguments but they still don't resolve my problem.
This is what i have, 2 sataII 160 gig drives. I am considering getting 1 to 2 more if needed. Don't plan on going raptor. Which way should i go for gaming? Raid (and which raid array) or just parallell? I'd rather not get 2 more drives but will if needed. Thanks for any advice guys.
oh, may even get an external hd.

Fools rush in...

Stick with the stand alone drives.
You'd regret any kind of Raid Array, except RAID 1.

RAID 1 will not improve your write speed, but actually will increase your read speed, compared to a single disk, and is the safest RAID using two disks... but also the worst cost ratio, resulting in 50% drive capacity.
