Hi,
RAID Level 6 requires a minimum of 4 drives to implement
Cheers,

I have seen messages by Neil from 2011 that he was planning to remove
this silly minimum requirement of 4 drive for RAID6.
IMHO, that "silly minimum requirement" *is* RAID6, 2xDATA, 2xPARITY. If
you make it 1 DATA, then you might as well have RAID1 with a hot spare
(not even sure how the calc's will work - for RAID6 like that, RAID1 is
easy :) )
I would use RAID5 for now, then migrate to RAID6 when you get a forth
drive. IIRC, you can always upgrade "up", not down (RAID numbers that is)
Cheers,
Pieter
