Im putting PBS on an R610 with maxxxed out RAM 192GiB I think and 1.8TB of SATA spinning disks. Theres tons of possibilities but its go time. Which way do you guys think is best for nightly backups and replication to a 2nd R610 and why?
 
1. 6 disks
2. As much as possible. I’ll eventually buy new larger drives but I’m working with what I’ve ve got, for now.
 
@BigBadBlack , as space is your priority, not performance, then RAID6.

RAID10: 5.4 TB
RAID6: 7.2 TB

And RAID6 has bigger fault tolerance: 2-drive failure in comparison with "at least 1-drive failure".
You can calculate capacity at https://www.raid-calculator.com/

Mind that RAID6 has poorer performance.
And that any hardware RAID doesn't support ZFS (which may be or may be not relevant in your plan).
