Concerning that the OP wants to use it for Backup PC, I would certainly expect quite a high ratio of writes where RAID5 is quite bad. To the OP: does 200GB difference (4 x 200 GB RAID5 gives ca. 600GB of data, mirror gives 400GB) means a lot to you? If the anwer is no, RAID 1+0 is better for you, if the answer is yes, buy larger disks and go to RAID 1+0 :-) If you have a hardware raid card, than the above doesn't really matter that much.
