No matter what setup you use, if you want redundancy, it’ll cost space. In a perfect world, 30% waste would allow you to lose up to 30% of your disk space and still be OK.
…but that extra percentage of used space is the intrinsic cost.
Comment on How dumb would it be to run single-node ceph?

What is you lose in space, you gain in redundancy.

Yep I feel this way.
No point in pricing a single HDD because I’m shooting for parity on every vdev I spin up.

Fair enough, it does add a good chunk of power usage though as HDDs are pretty power heavy at 5-7W or so.
