so what should i do? ive got the seagate barracuda as my main drive. it works well and everything. but i think i want to get a raptor because its faster and apparently games run better on it. so i guess id run the seagate as the main drive and have the raptor secondary. no raid or anything because obviously that would be pointless between those two drives. however, what if i just get a second seagate drive and put them in raid 0 ? that is a cheaper alternative but will it be as fast?
