Raid questions

[jmh547]

Is it possible to run raid 1+0 with three drives (i.e. 80gb+80gb and 160gb) or would the 160gb bog the whole thing down?

It'll certainly be possible in a sense: run the two 80's in RAID0, then do a RAID1 across the RAID0 volume and the 160 GB non-RAID volume. In Linux LVM will be able to handle this fine, but in Windows you may have to do the RAID0 with chipset drivers and the RAID1 with Windows volume thingees.

Performance-wise, who knows ... try it and see :)

1+0 or 10 requires 4 drives.
And the bigger drives will be lopped off to the size of smaller ones in GB.

It would be possible to do raid 0+1 in both linux and windows (windows would probably require using the chipset raid for part), performance would more than likely be affected. How much I don't know (and it might be worth it to go with RAID5 loosing 80GB of the 160GB drive).

The following page shows the difference between RAID 0+1; 1+0, etc.

Raid 10 and 0+1 take four drives at minium.
If you read the wiki you'll see that its raid one over two sets of drives. 4 and 6 drives would work fine.

running linux and XP on an array would eaisest to be done by partioning the array as if its a drive when installing XP. And yea both OS's would need to have drivers for the array.

I dont particualry like raid 5 without a decent controller unless its for a storage server on an average speed network.

You could Raid0 the 80GB drives and use the 160 as backup. Or save images to the 160, have some storage and/or possibly the linux partion.
How much falt tallerance are you looking for?

It would't be strict RAID 0+1 since one of the 160 GB volumes would be RAID0 and the other would be vanilla. So maybe RAID (0,JBOD)+1? Be kinda interesting to see how well it wroked enyhow :)

^ good luck getting a controller to do that mess :p

And onboard raid :eek:

You can give that a shot and tell us if it even works :D
