2 SSD 1HHD in RAID10?

Specs: Win7/Debian, 16GB
Can I run 2 240GB SSDs and 1 500GB HDD in RAID10?

I was wondering if I can do this or do i need a second HHD? I have a second 500GB drive if needed but it seems like a bit much. I would like to have the 2 SSDs striped and mirrored onto the 500GB HDD.

What do you hope to accomplish by doing this? Just because you can? I think the mechanical mirrored drive will drag the added performance down. For personal use I don't see that striping will add enough performance to warrant the expense.

It is always best to have matched drives for any raid. I guess you could try it but the speeds are so far apart it might use a lot of ram and cpu in the process.

Whether or not it can be done would depend on the controller used. But even if possible it is doubtful you would see any significant performance gains. Remember that no form of RAID will avoid the need for maintaining backups. RAID (except RAID 0) protects you from drive failure. It provides no protection whatsoever from other causes of data loss.
