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.
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 a counted for that with backups. 👍
Super jealous. Half for storage and half for backup or just going all storage?
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.

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 would probably depend on case, motherboard, and which (if any) pcie slots are occupied.
With that amount of storage I highly recommend RAID6.
I’d do a pool with 2x vdevs, each with three drives in raidz1
