Raid 1 a Raid 0?

[Dopekitten]

Alright, my question is that if i have 2 500gb hard drives, and put them in Raid 0, can i put that in Raid 1 with a single 1tb hard drive?

It will depend on the flexibility of your RAID controller. It is possible but not every controller will do it. Check with the manufacturer.

It may be possible with Linux software raid under mdadm but I would not try such a thing with a generic motherboard raid controller if the data has any value since such an uncommon configuration will probably be poorly tested/supported.

If you're using your motherboard's built in RAID (ICH9R or whatever), more than likely not.

You would be limited to the speed of the 1TB drive and wouldn't get any benefits over 2x 1TB in raid 1.

It's definitely possible with Linux software RAID, you can do pretty much any combination that you can think of with Linux software RAID. I'd guess that if an onboard controller supports RAID10 it'll require 4 drives of the same size, so that probably won't work. And Windows software RAID won't let you do any form of redundant RAID unless you buy a server release so that's probably out too.

One benefit would be not having to buy a second 1TB drive if (s)he already owns two 500G drives.

Good point Nothinman.

Also, if the OP is asking about RAID-1 he's looking for redundancy, not speed.
