Strange Raid Combination

My hdds are getting a bit old, and I'm thinking it wouldn't be a bad idea to safeguard my data on them.

I currently have a pair of 750GB hdds of different companies and rpm.

I would like to add a single 1.5TB drive, then combine the two 750GB drives into a RAID 0 and form a RAID 1 between the RAID 0 and the new 1.5TB drive.

Is this even possible? Will I need a fancy or multiple raid controllers to do this? It seems kind of like a RAID 10, but it isn't exactly the same, so I don't know if it will work or not.

Thanks!

Do you currently do backups to offline media? If not, then that's what you should be doing. There are lots of risks to your data that RAID won't protect against. Good backup strategy means keeping at least TWO copies of your data on OFFLINE media, one of which is stored OFFSITE.

With a combination of software and hardware raid you can do this, but don't. Like sminial says keep the best stuff offline. If you insist on data integrity inside your case, raid 1 with two 1.5 tb drives. Or just get one 1.5 tb drive and a HD toaster and antistatic bag. Store your most important stuff on one of those drives, disconnect it and only connect it every once in a while to copy new stuff onto it. One lightning stike can kill a raid 1. One house fire can get the offline drive in your closet too. It just depends on how paranoid you are or want to be.
