first of all, I don't know RAID 6, only RAID 0,1,5 and 10...
maybe I missed something.

also, compared to what?

anyhow,
* write performance will be a bit slower than normal disks or mirrored disks.
* read performance will be faster than normal or mirrored disks.
* space utilization is better than mirrored disks, but lower than normal disks
* fault tolerance is of course better than normal disks, but the same as for mirrored disks (1 disk can fail, and can be replaced online)
