another raid question

[Death-Evil]

So I'm about of buying 2 hitachi 250GB sata II drives. I want them in raid 0 for best performance.

1:how to raid them?
2:after I raid them, will I have one disk 500gb or 2X250GB?
3:Will I be able to make 4 partitions without loosing any performance?

If I will get them then my current ATA133 will go to my father's computer

I would like to setup them

c:Windows 15GB
d:Games 30GB
e:Tools 30GB
f:Others the rest of the space

is it possible???

Thanks in advance

PS: which program use for partionalizing the disk?? partition magic?

You will end up with one 500gb Partition. It will actually be a little bit less on account of the file tables. You can partition the drive without losing performance as far as I know. To raid them your motherboard must support RAID. Refer to the stickys in this section for more info.

tnx a bunch, I already ordered those bad boys.

Edit: one more thing, if usinfg raid 0 I heard it's dangerous. Can somebody explain it to me? will I lose all data 500GB when something goes wrong?

how much fatser will be raid 0(speed) than raid 1(stability)?

Thanks

Raid-0 is twice as fast as raid-1. If one of your drives screws up, you'll lose everything on the array. But look at it this way, one drive messed up, you lose all your data but you still have one drive left. You have one 500gb drive, lets say, and it fails, you lose all your data anyways but have no drives left. So IMHO, the whole Raid-0 data loss risk is over rated.

so it happens only when one of the drives goes dead right?
