I bought a rockpro64 and a NAS case with space for 4 drives, I added a 4xSATA PCIe card. Right now it's a 4x4TB ZFS setup that has been running as my own home storage for over a year continuously. Very happy with it.

What kind oft write speeds do you get on zfs?

I also have a rockpro64 with two 8tb WD red pro and in subvolumes with encryption i only get 70MB and in non encrypted 110MB. I already switched from aes256-gcm (the default) to aes256-ccm, since that is less taxing ob the CPU.

I Start to get the feeling that zfs arm is not yet optimised enough.

`cryptsetup benchmark`

shows me ~400-500 MiB/s (per core) for aes-xts-256 on slower rk3566

I guess it will be similar for gcm

Are you running zfs native encryption and zfs mirror/RAID or luks + mdadm with zfs in top?

No, just showing output from a tool that uses kernel based HW accelerated primitives on the platform.

how are you measuring it?

Do you have a link or model for the NAS case?

this is the case: https://www.amazon.com/gp/product/B00J353KH8/ - had to modify it a bit to fit the rockpro at the bottom, use an ethernet extension to connect the cable from the back and a hacky switch to turn it on. But it works now and it's pretty stable.
