Is this possible? RAID 0+1 with three drives

Hi all,

Shortly, I'm going to have an extra 1TB drive. Currently, my desktop has a RAID-1 of two 500GB drives (specs in profile).

Does anyone know if it is possible to do a setup where the two 500GB drives would function as a RAID-0 stripe, and the 1TB drive could mirror the stripe? If anyone has any information, I'd appreciate it.

Thanks in advance.
 
As Protias states the short answer is no.

You may want to consider RAID 5, the net effect would be the same with 1TB of storage and you can lose any one drive and still recover.
 
Yes, I can do that. Just wondered if this was a possible option as well. Thanks for the replies, guys.
 
Again, if you are going to RAID5 the drives, you are going to only be able to use the maximum amount of space of the smallest drive. So you are going to lose 500GB of that 1TB, then you have the parity bit, which is the equivalent of one drive, so you have a total of 1TB of use.
 
Exactly. I've set up RAID-5 arrays in Dell servers at work many times with SCSI and SAS discs, but had thought Intel might have done something with Matrix RAID or something like that that would have let me do this, and was checking to see if someone had already done it.
