    I think in your case with only 8 spindles would be better then breaking them into 2 smaller arrays. If you had 14 spindles then I would use 2 RAID 10's.

    Some information that I found to be useful.

    here's the thing to do for good I/O performance:

    1) Use a LOT of spindles. If you go to http://www.tpc.org
    and look at the specs on the designs to achieve maximum database
    performance, you'll notice they use hundreds of drives. By a lot of
    spindles I do not mean large RAID sets. You should concatenate many
    smaller RAID sets into a single LUN either by using host software or LUN
    virtualization within the storage hardware, if it has that capability..........
    All the best,

    i myself wouldnt go with raid10 on all 8 disks, no hotspare, most propably all disks are of the same production series, in worst case with 'just' 2 failing disks you are going to lose all your data

    if you need speed think about going with raid10 from 6disks and 2hotspares, or if safety is more important then raid6 with 7disks and 1hotspare

    I've never liked the idea of a hot spare, I've lost a 4TB raid to the gods thanks to a hot spare and auto rebuild.

    Open-E cover off the reason's why... worth a read.
