RAID question

[Dazednconfused]

Hi,
I have just done my first build.
I only have one HDD, a SATA 11.
If in the future I add more drives, will I be able to set up a RAID configaration and keep my OS and data intact? Or does this have to be done from day one?
Thanks for your help.

Depends, some RAID controllers, etc will allow you to mirror your drive to another no problem.

If you want to go RAID-0, this might be more tricky.

If you want to boot off the RAID, you'll probably need to re-install anyway, I think. Some of the bods will turn up with info soon, I'd think.
