Reinstall Windows on raid array

Question

Hello all,
I have 2 arrays running a 0+1 which windows in installed on and a raid 1 which my games are installed on.
I originally built the array after windows was installed so I didnt have this issue....
I want to reinstall windows on the same array and to do so would be boot from the cd like normal and F6 and install the raid drivers and windows should then see the arrays.  Pick my array to install to and away I go...
Second question I assume running my games/programs from a 0+1 array would work better than the raid 1?
Tell me if I'm missing something.  TIA

Tiresmoke, I think you missed the part where he said RAID0_1 and RAID1.  He has two arrays, the first is RAID0_1 which mirrors stripe sets (see here: http://www.acnc.com/04_01_0_1.html), and the other is RAID1 which is simply a mirror.
That being said, I'm about to try the same thing.  I just bought 3 additional WD Raptor 74GB 10K SATA drives and am doing some basic IOMeter performance testing now before creating a 0+1 set.  Wanted to quantify the performance gain, I'll post it in a new thread when I'm done.
As for your first question, yes, you'd want the latest nVidia RAID drivers on floppy to inject into the install with the F6 key.
For the second question, the performance of a stripe set is superior to that of a mirror set, and a mirrored stripe set beats them both.
Let me explain:
Normal access (non-RAID) would write to one disk.  When reading, it would read from one disk.
On a stripe set (RAID0), you write to multiple disks (doubling, tripling or quadrupling your write performance depending on how many disks 2, 3, or 4), and the same with reads.  But you gain performance, but no redundancy, and in fact increase your risk of failure (any drive dies and you effectively lose all of them).
On a mirror set (RAID1), you write to two disks simultaneously (no performance gain, but failure protection), but you can read from both disks simutaneously thereby doubling your read performance!
On mirrored stripe sets (RAID0_1) you gain the performance gain of the stripe, with the added redundancy of the mirror.  You get 2-factor read performance improvement along with redundancy.  If it were possible to add more disks to it, you could realize even better read performance, but alas you can't use the two Silicon ports in the nVidia RAID set.
That make sense?
