RIAD Can RAID 1 have more then 2than two drives?

recently I've gotRecently I had a discusiondiscussion with a teacher of mine. He was claiming that you can do raid-1could set up RAID 1 with 5five drives. And and that the data waswould be mirrored over all 5of these drives.

I told him, raid-1 a RAID 1 with 5 drives does notwouldn't work like that. It wil dowould be a raid-1RAID 1 with 2two drives and would use the other 3three drives as hot spare.

I dought his answer becouse he wasHe also sayingsaid that raid-6RAID 6 is identical to raid-5RAID 5 but you can place all the parity checks on the same drive. I thought raid-6RAID 6 was an raid5a RAID 5-like solution where 2two drives where used for parity.

Who's right. :p

Thanks, then?
