Hi All, just a quick question to clarify my understanding of which RaidZ option to use. I have read the manual, resources section and ZFS primer, but just wanted to be sure that I have read and understood it correctly.
I plan to build a new box with 8* 8TB WD Red, giving a total of 64TB usable data in one vdev:
If I've understood this right, I be going for either RaidZ2 or RaidZ3 (not made my mind up yet.
Thanks.

I plan to build a new box with 8* 8TB WD Red, giving a total of 64TB usable data in one vdev:
- If i use RaidZ, this means I will get a total usage capacity of 56TB with the fault tolerance of 1 drive failure before I lose all data.
- If i use RaidZ2, this means I will get a total usage capacity of 48TB with the fault tolerance of 2 drive failures before I lose all data.
- If i use RaidZ3, this means I will get a total usage capacity of 40TB with the fault tolerance of 3 drive failures before I lose all data.
If I've understood this right, I be going for either RaidZ2 or RaidZ3 (not made my mind up yet.
Thanks.
