that's like BASE jumping with a large umbrella, as earlier noted. Don't do that, it'll just hurt you. At least use RAID-5 and preferably use more RAID sets and RAID-0 or LVM on top.Make that RAID-6
I agree. I think a more sane outlook on this would be 19 drives made up of: * RAID Level: 6 * Hot Spares: 2Using RAID5 then its not a matter of if you are going to lose your array, its a matter of WHEN considering the number of spindles here.
If you have the drives in separate enclosures or different controllers, have one spare per controller - ie don't but both spares on the same controller.
*Maybe* if you are pushed for space, only use 1 hot spare - but be sure to have a drive sat in the anti-static bag on a shelf within walking distance of the server.
