Is it possible to add a RAID configuration and add another after installing more drives?

For example, I want to install two hard drives and put them into RAID 0. Then I want to add two more hard drives and put them in RAID one a month after I put the first two hard drives in RAID 0. Is this possible?

Also, does that make the configuration RAID 0+1?

You can do it, but it might be more trouble than what it's worth....

That doesn't make it 0+1(RAID 10). This would just be two striped arrays.

Can't see why it would cause any problem.

When you put 2 HDD in RAID it makes them work as one, either for performance or stability, or others but never mind those.

So putting 1 set in RAID1 and another in RAID0 it is the same as having 2 hard drives, 1 super stable, the other super performance.

Just remember to back everything up in the HDDs you have now in RAID if you plan on changing because they must be blank to do it

Why do you want to put them in once a month? I have a Raid-0 setup too.

Because it's going to take me a month to get the funds to buy HDDs for RAID 1. I already have the two VelociRaptor HDDs that I want to set-up in RAID 0, that's why I wanna know if I can do the second RAID and HDD installation at a later time.

Would it be easier/possible to just have the 2 Velociraptors in a RAID 0 setup and then just have like a 1TB hard drive to back it up periodically? AFAIK hard drives don't fail that often so it might be cheaper and easier to manually back it up. Would that work?

Maybe I'll do that. I was just looking at RAID 1 because it's faster in performance than a slave drive, but also mirrors the drives so in case one DOES fail the other will still have the data. As far as I know, if the slave drive fails, everything's gone.
