With RAID6, any two disks can fail and the array will still be online. EDIT: The author has also demonstrated that they've gone through various growth permutations over the years. 4 disk RAID6 under md-raid has a supported growth mechanism, allowing you to add additional disks and have it restripe data automagically for you. It's not a good idea as far as performance is concerned, but for a home use nas that is primarily intended for streaming media, it's not a major issue, and enables you to grow to your heart's content (even if it is a bad idea, as I successfully proved growing from 4 disks to 16 over a few years, before respinning as multiple 6-disk arrays)
