In what way?
I would expect this to be similar to Raid 5 performance depending on how the
parity is calculated, but you get extra fault tollerance.

writes due to having to wait (sometimes) for the second parity write to the
extra disk. This could be a performance drain on write-intensive (i.e.
OLTP) databases.
