Hi, I have two 500GB Cache drives.   Unraid tells me I have 500GB of usable space in the pool.   If I add a 3rd 500GB will that give me 1TB of space or still 500GB?   Thanks.

Neither. You will get 500 x 3 / 2 = 750GB space with the default BTRFS RAID1 profile.

 

If you rebalance to RAID0, you will get 1.5TB

If you rebalance to RAID5, you will get 1TB.

If you rebalance to RAID1C3, you will get 500GB.
