The drives need to be empty first, but from then on you're fine. Also, you can't use a space as your system drive.
I just set this up on my desktop at home during a rebuild:
I have an 80GB drive, and three 500GB drives. I installed Windows 8 on the 80GB drive and I added the 500GBs to a storage pool and made four spaces in the pool.
- 1TB "Media", parity
- 100GB "Documents", 2-way mirror
- 500GB "RecordedTV", simple
- 1TB "Backups", simple
Parity does have a big hit to write speeds (haven't benchmarked, but from what I read it tops out around 35MB/s), but since I won't be doing writes to it very often, I chose it for the extra space (RAID 5). I write to Documents a lot, so I chose mirror (RAID 1). The others, I don't care if I lose, so I left them at Simple (RAID 0). If one drive dies, my simple spaces will simply lose some files while my others will continue running. Once I add another drive back in, the parity and mirroring will automatically rebuild in the background.
You'll also notice that my drive sizes add up to larger than what I have. This is fine because of "thin provisioning". Windows reports the drive sizes as I specify, and will give me a warning when I'm running out of physical space. When I need space, I can simply add more drives to the pool and Windows will automatically start using them in the spaces.
