Then wtf are you doing here?
OT:
RAID 5
you can use any hdd in raid-1 with mdraid on Linux.
Actually i think it's "you can't use raid5 with 2 disk"
AFAIK, not 100% sure though =D
RAID1 is with 2 disks, you cannot use 3 disks. With 4 disks it would be RAID10.
RAID5 needs 3 or more disks.
RAID 1E. Falta que el software/hardware lo soporte, claro.
Are you sure what have you said ?
Simply said, RAID1 is a mirror. Even number is required to have mirror.
RAID1 = Min 2
RAID5 = Min 3
RAID6 = Min 4
RAID10 = Min 4
RAID50 = Min 6
RAID60 = Min 8

That's a new one. Never heard of that level before. I think I would just stick to RAID 6 or RAID 10 if I had 4 or more disks, RAID 5 with 3 disks. RAID 5 and 6 would kill your throughput, depending on how many disks you have, though.
What would be the overhead of RAID1e vs RAID5 on a 3 disk setup?
+1 Raid 0 = Min 2
But, yes, you can create RAID1 with more than two hdd, using mdraid, in Linux. Off course, this is not a standard raid level, but you can do this: https://raid.wiki.kernel.org/index.php/Introduction#The_RAID_levels
In this case every write and read is going to all of these disk.
