RAID Configuration

[usp97]

I have a question about RAID configuration and possible conversion from one RAID type to another. Currently, I am putting together the following build:

HP Proliant G7 N54L MicroServer
Kingston 2x8GB RAM (KVR1333D3E9SK2/16G)
2x3TB Seagate Barracuda (ST3000DM001)
2x3TB Seagate NAS HDD (ST3000VN000)

Unfortunately, I am not in a money is no object situation. So, I am slowly buying the pieces when they are on sale and so they are on separate credit card statements. Here are my questions:

1. My plan was to set up a RAID 10 configuration. Am I correct in thinking this is my best set up for the 4 drives?
2. I would like to get my box up and running as soon as possible. Can I start with 2 of the 4 drives in a RAID 1 configuration and covert it to RAID 10 when I get the other 2 drives?

Thank you very much for your help.

Glance though the forums and you'll see why this is a bad idea that unfortunately has dire results of people loosing data for good.

Yes, that is possible. You start with one mirrored vdev and later add another one to extend the pool.

DJ9: ??? He didn't mention RAID5 at all.

Just as Dusan said. I explained how to expand pools in my presentation in the noobie section....

Sorry about that. I shouldn't reply to stuff when I'm half asleep.
