windows raid implementation

I am looking for a bit of background about how windows software raid works.

If I have four disks and raid 5 three of them, using windows software raid,  and then have the windows instalation on the remining disk.  Will the raid 5 set up still be available if the windows disk is formated and windows reinstaled?

Secondly if I partition the disks can I raid them indipendantly.  I.e If I have tree disks and partion them so they each have an 10GB and 50GB partion can I raid the 10GB together indepandantly of the 50GB so I would have two raid 5 disks on three drives.  All using windows raid tools.

Hope that makes sense

-> Yes, but you will have to "import" the disk in "disk Manager" console. The RAID 5 config is written disk LDM on the disks themself

Secondly if I partition the disks can I raid them indipendantly.  I.e If I have tree disks and partion them so they each have an 10GB and 50GB partion can I raid the 10GB together indepandantly of the 50GB so I would have two raid 5 disks on three drives.  All using windows raid tools.
-> Yes with W2k3, not 100% sure with W2K, but I would assume yes.

-> Quick question, why using Soft RAID when a Hardware controller is not too painful costwise ? RAID5 Software will impact notably your performance.

Thanks for the answer.

->Partly curiosity, and I don't have a raid config I can purposfully crash.
Also I'm looking after an older server that's going to be upgraded soon so don't want to spend the money buying bits for it.

Thanks again

make sense :)
but for production sensitive machine, hardware raid is definitively the choice..
