Where do you get this info about low durabiltiy (please link)? I understood one of the benefits of optane memory was that it had better durability than NAND flash. I’m not disagreeing with you, I would just like to read more on it.
So if Optane is the best L2ARC cache device, then what are the best SSDs to pair it with for raidz2 (besides more Optanes, of course)? 
Old thread I know, but it seems to have been resurrected.
Intel has made the Optane 900p and 905p as well as their datacenter DC P4800X. These are all NVMe / PCIe drives.
I have a 905p as the primary boot drive on a Linux workstation of mine. It works great.
If you have an all SSD zpool… a cache device should not be needed.

Ya, but running root FS on Optane vs raidz2 SSDs without Optane? I’d like to see some benchmarks… Hopefully Phoronix will make some benchmarks more like this - anyone know if there’s a way to make suggestions to the Phoronix guys?
