From the looks this isn't raidz1, and i can't say from this what it is.
(please run 'zfs version')
In my case:
This is how raidz1's should looks like

this is example of performance (on this setup)

Sure, but they aren't and controller thinks they are spinning rust, resulting in less performance.
Once I got SHIT results in RAIDz1 ... I reverted to ZFS RAIDz-0 (striped) ... I mean, if it can't outperform my RAIDz2 spinning drives with no condom? There's SOMETHING wrong; whether it's the optimization, the SAS controller !?, something ... bc there's just no excuse for it to be slower without parity and working all in parallel than having lost 2 drives to parity.
Anyway, i'm on the warpath to seeking out either an R7415 or if I can find a good enough deal an R7515 ... think it's worth the "future proofing" of people able to get the most out of PCIe 4.0 NVMe SSDs for the modest difference in price between the two systems..? So far it looks like it'll cost me about 500 extra to get the version compatible with Epyc 2 and Epyc 3 as well as off the bat (due to Epyc 2) upgrading the PCIe to 4.0 ...?
Thanks for your response and time, as always!
