What should i do?

Alright, after reading about RAID and stuff, i was wondering, if you put 2 hd's at different capacitys, The total capacity would be the (smallest drive * the # of drives) right?

Right now i don't have a desktop but in the future i'm planning to buy one and i already have a 7200rpm 2mb 80gb and a 7200rpm 2mb 120gb, so if I ran these two in RAID-0, i would only get a total of 160gb?

My brother also has two 40 gb hd's one is 7200 rpm, the other is 5400 rpm and ata66, how could the performance of raid-0 work on this setup?

So i could either lose 40gb or have less performance right? So what would you do?

I also plan to do video editing once i get my new computer.

If you ran 80 gb hard drive and your 120 in raid 0 then you could only use 80 gb of it. The smallest drive is how much info you can place on them. Raid 0 means you have 2 copies of your os on both disks. Theoretically it would be twice as fast. The performance of the slowest hard drive is what you have to go by. Your brother would have 40 gb total. The best thing to do would be to get drives with the same performance and storage for best raid configuration.

I know this thread is really old, but I came across it in a search and thought I'd add my 2 cents. Since you've got 2 drives of different capacities, why not use the striping feature in W2k and XP? It's not exactly RAID, but it will improve performance. You have to upgrade your Basic discs to Dynamic to do it, but that's no big deal.
