raid2 will survive the loss of 1
wiki disk

RAID 2 can recover from one drive failure or repair corrupt data or parity when a corrupted bit's corresponding data and parity are good.

more than 1 disk allows you to restore only raid1 and raid6 and combinations with them are
the most cost-effective on disks, of course raid5 and raid6 (the more disks in the array, the less 'space' is wasted)
