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.
John|||I would expect it to be at least a millisecond or two slower on average for
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.
