I build 100Tb+ openzfs like everyday, well recently i am building
tiny ones(20Tb or so). In zfs you can build smaller raidsets that
you can combine together to create a pool. So when you go to
rebuild, it doesn't take as long, especially on bigger systems. Also
it doesn't resync, it resilvers only coping the areas of disks that
has been written to.<br>

<div>Thanks for the replies... On a related question: I am
researching an affordable solution for a 72TB NAS to store the
snapshots. Following some conversations of others doing the
same, I am reading that a failed drive can take a very long
time (many days) to rebuild a raid 6. We use quite a few
Synology units with far less capacity, and like them. Is
there a recommended raid configuration that would have more
acceptable rebuild times? Couldn't imagine having to watch a
raid rebuild go on for days.<br>
