Need advice on storage - directory in zfs pool or just zfs for vm

[pvanthony]

I am newbie and need advice on storage.

What I have done is to create zfs mirror pool with two 14tb sata hard drives. (datamirror)
Then I created two directories in proxmox. One for vm and another for ISOs and backups.

Is this the correct way to manage storage?
Should I even use directory or I should use zfs directly like what was setup during installation. (local-zfs)

Here is the screenshot of the storage.

Usually you won't need an own directory or dataset for vm/lxc storage. Instead you would add the ZFS pool as Block storage, afterwards create a dataset on it for the template/snippet and isofiles.

Block storage has less overhead and thus the recommended variant but directory would work too.

Please keep in mind that hdds are great for bulk data but not so great for vm/lxc performance. So I would setup vm system and App virtusl disks on a ssds and add hdds m-based virtual disc for data storage
