2 to 1 to 2

hey guys, this might be a weird question, or it might not. i have 2 wd 320gb sata II drives that i want to set up in a raid 0 array. i also want to run a dual boot system, using xp pro and vista home premium.

if i stripe these 2 drives, and then make 2 partitions on it (one for each os), am i doing anything? i mean, i'm making the system think it's 1 drive, but then i'm splitting it into 2 again. will i still see the performance increase, or will it cancel it out?

i don't feel like doing all that work to find out it was for nothing, but i will do it if i still get the benefits a raid 0 array offers.

Yes, you will see the performance gain still. When you create two partitions on one hard drive, you aren't getting any lesser performance.

but i'd be creating 2 partitions on 2 drives, not 1. well, one if you're counting the stripe as 1. no one has been able to answer this for me. if you say i will still have the benefits, then i'll try it . but if it doesn't work.......

I know exactly what you are saying, you are setting up two hard drives in RAID 0 and creating two partitions. The speed will be the same on both partitions as if you had kept just the one, as long as there is no activity on the other partition.

thanks, i think i understand now. it's almost as if the raid stripe goes perpendicular to the partition walls, not parallel to it, so the raid setup still applies. that's kind of a weird way to put it, but if you use your imagination, it explains how it would still work as an array.
