    The idea is going for raid5 so that should be around 100TB of storage, minus the OS and apps, etcs. But easily 80TB+ net storage.

      With drives that size, you should be talking RAID6, 80TB storage and 40TB checksum.

      Rebuilds will take a long time, and with RAID6 you can at least suffer 2 drives failures and continue to operate fully.

      I use a 1tb ssd for the os/apps with my raid5 strictly for storage. Kinda nice if the os needs to be reinstalled or I want to migrate the raid cluster.

        but that means you need to give up a bay slot for the system sdd, right?

          In my case, I use a PCI card with an m.2 slot for my OS drive. I lose a PCI slot, but I already had a few to spare.

          That’s also a good option but I wouldn’t with 6 drivers personally. I have a 12 bay array with two pools of 6 each running raidz2. I’ve run raid 5 for a long time but have had one drive fail many times and always have mini heart attacks while I wait for the new drive to come in and the rebuild process to happen.

            I do this for expansion. I can expand the pool three drives at a time instead of 6. But, I set it up knowing the risk with a single parity drive…and I’ve acounted for that with backups. 👍
