    I am currently using 2 16TB drives in Raid 1 and was planning to move to Raid 5 (or maybe it was 6) if I need more storage by adding a 3rd drive.

    What would you recommend instead?

      RAID5 is risky on drives that large, there’s a decent chance of a read error during a rebuild.

      RAID6 will provide more protection but you lose two drives worth of capacity to the parity data. I’m not sure if a three drive RAID6 is actually possible but a three way mirror would be more sensible as you’ll avoid the extra computation of parity calculation.

      Imo RAID6 starts to make sense in an array of 5 or more drives.
