RAID 0 across two drives of non-equal capacity

[Catalyst18]

Hello,

I just recieved a Maxtor 120g 7200RPM SATA drive for Christmas, and I am wondering if I can pair it with my existing Maxtor 80g 7200 RPM Sata in a RAID 0. My board, an MSI KT6 Delta-LSR supports RAID 0 with SATA, but I am wondering if I can use two different sized drives. I know the size of the array will be twice the capacity of the smaller drive (80x2=160gig). Any insight? Thanks!

yes, raid 0 dont care, especially when 1 drive fails

opps, to answer the second question, ur total size will be 120 + 80 = 200 gb

raid 1 will take the smaller of 2

You would see better performance with each drive on their own channle which is what you would get with SATA anyway. Then load balance your heaviest used data across those 2 drives.

Why do you want RAID0? It doesn't increase FPS in games, just shortens map/level load times a little, while doubling your chance of losing all of your data.

I was thinking speed with Photoshop, but tallman's idea sounds just fine. I have enough speed, what I need now is capacity and speed only if I can get a significant gain with RAID 0.

Thanks, and Merry Christmas to you all!

EDIT: But wait, I would not see a significant gain if I paired the two in RAID? I am sacrificing a bunch of reliability, so this is important.

To clarify, if I were to arrange a Raid 0, how much space would I end up with?

The smallest and slowest of the HD x2...why waste the extra space? See if the MoBo supports JBOD

I have the same setup. 2 maxtor drives. one 120gb and one 80. They are the same models though. If you do raid zero with this setup you will have 160gb... well 152gb because windows calculates in differently. It works fine though.
