Hardware/environment
24 drive bay case
4TB drives, all same make/model/etc., purchased within last year so not all same manufacturing lot
64 GB RAM.
Home use
Mainly for personal data, home office backup, ESXi homelab datastore.
Max 2-3 machines will access data at once.
Possible ZFS configurations, arranged by number of disks
20 disks
raidz2 = 1 zpool, 2 vdevs of 10 disks, 2 can fail per vdev, 4 can fail in total
32TB per vdev, 64TB total usable, 20% of total drives can fail
22 disks
raidz3 = 1 zpool, 2 vdevs of 11 disks, 3 can fail per vdev, 6 can fail in total
32TB per vdev, 64TB total usable, 27.27% of the drives can fail
24 disks
raidz2 = 1 zpool, 3 vdevs of 8 disks, 2 can fail per vdev, 6 can fail in total
24TB per vdev, 72TB total usable, 25% of total drives can fail
Or should I go for something else?
