Creating a RAIDZ2 with 10 drives is an OK setup?

Is there a method that will allow the creation of storage pool that provides the ability to expand storage one drive at time that offers parity protection while maximizing available storage?

There is a plan in development that would allow a single disk to be added to a RAIDz2 vdev to expand capacity. It may be more than a year before that feature is available. It has been in the works since 2017. Take a look at this:

RAIDZ expansion, it's happening ... someday!

If you've not already seen it, RAIDZ expansion is happening. The OpenZFS project tweeted this earlier today. RAIDZ expansion (most requested ZFS feature ever?) is coming, courtesy of @freebsdfndation. Sneak preview at OpenZFS DevSummit! https://twitter.com/OpenZFS/status/921042446275944448 So...

Regardless of the ability to expand a vdev by adding more disks, no vdev should have more than 10 disks. Best performance is had by adding more vdevs.

You might want to take a look at this video because it tells a lot about ZFS that could help you make some decisions.

@Chris Moore Interesting about the loudness of the drives, I was under the impression that WD drives were a little quieter than Seagate.

I think this is the same / similar question that I already answered elsewhere:

First FreeNAS build hardware recommendation needed (relocated)

Bargain! A nice chipset and mATX too, might be time to upgrade.

It is a moving target. Every time a new model comes out there is the potential for a different answer. I have had some Toshiba drives also and the ones I had were even quieter and cooler than the Seagate drives, but I had an unacceptably high failure rate from the model Toshiba drives I had.
Here is a link to a post I made about it:

How do you burn in new disks?

I got bit by a WD 1TB Black drive a couple years ago. I dropped it in my workstation, installed Linux, and "moved in"... Completely, ssh keys, PGP keys, etc... Powered it off and went to bed. They next morning, I powered it on and it went "ker-thunk... click", and that was that. I then faced...
