> What is it about RAID6 that you are not comfortable with? I've never use it :) Here the deal : I have 5 drives on my NAS, I can't have more in my tower (1 drive for the system, 5 drives for the NAS). From Adam's message, it should be enough for setting up a good RAID 6. For now, I have a RAID 5 with a spare, meaning that I have 3x(drive size) as available size. I can have 2 hard drive failures. If I setup a RAID 6, if I understand well, I'll also have 3x(drive size) as available size, I will also can have 2 drive failures. As I read that algorithm on the RAID 6 are way more complex, and rebuild time is longer, as I have only a Atom D510 as CPU, I consider that RAID 5 is a better option. But if you can explain that RAID 6 have pros I haven't seen, I'll surely swith to RAID 6 (always want to learn :) ). Thanks, gUI -- Pour la santé de votre ordinateur, préférez les logiciels libres.
