what is the best disk configuration for SQL 2000?

Database is 10GB

OS  --  Raid 0, 0+1, 1+0, 5
Data -- Raid 0, 0+1, 1+0, 5
Logs -- Raid 0, 0+1, 1+0, 5

I'm not too concerned about performance while in a degraded state, i.e one drive fails.

I need SPEED...

And most importantly, why choose any one raid over the other.

    RAID 5 is pretty quick

    I would make 2 containers in the hardware RAID manager.

    Container 1:  OS   8GB
    Container 2: SQL Rest of RAID space

    Keep the data and the logs together, don't want the server writing data all over the place.

    For an explaination on RAID,  check this out:

    I would just suggest RAID 5, sure performance is shot if a drive fails, but it's faster than RAID1 and less vulernable than RAID0.   RAID 0+1 is quick, but you pay a pretty penny for it.  Plus RAID 5, you can do with 3 drives, RAID 0+1 require more drives (4 or more).

    If money is no problem you should go with RAID 10

    Go with Hardware RAID 5. If you lose a drive, simply plug in a new one and let the controller rebuild the new drive. It's a fast operation and you shouldn't have to reboot the server.  And if you can, off load the database9s) to a seperate server.
