Another RAID Question

I just finished building a pretty powerful machine, but I haven't bought any HDD's yet. I want to make sure that I can expand my storage in the future, and would like to run a RAID setup. Would it be possible to take 2 2TB drives and set them up in a RAID 0, and use a 4TB drive to run a RAID 1??

I only ask because I only need 2TB of storage right now, but in the near future, I may be expanding to 4TB and would like to keep at least a RAID 1 on all my information.
 
you do not need to get a 4 tb drive for doing a raid 5. get 3 x 2tb drives, set up a raid 5..that way you get raid 0 performance, with semi raid 1 redundancy. with this configuration, if one drive fails just replace and it will rebuild all data and raid. or you could get 4 x 2 tb drives and run a raid 0/1...raid 0 performance, with 100% raid 1 redundancy. if I am incorrect, someone please clear my misinformed mind up.

They way you talk about setting this up, it seems like you want 0+1 or 1+0 (yes they are different).
0+1 is stupid. (one drive dies, you lose a mirror)
1+0 requires 4 of the same size hdd, or otherwise 4 HDD's and will become the size of the smallest. If you can afford the drives, this is the best performance/redundancy option (imo)
If performance is more important, do a raid 0 setup now. Otherwise, I'd suggest doing a raid 1 setup, and then turning it into a 1+0 setup later.
