10GBE with OS6 on ReadyNAS
Has anyone looked at the lspci or similar output of an OS6 ReadyNAS with 10Gbe hardrware to see what chip set it uses? I know they use the Intel X5x0 series in the OS4 and ReadyData rack-mount units...

The NAS have hard drives, not SSDs, but a pretty powerful CPU and lots of RAM, so the drives are going to be the limiting factor once the network no longer is (another reason to stick with 2.5Gbe).
Even with 2.5 Gbe you might well end up limited by the network.
This reviewer measured sustained file transfers in the 5-6 gpbs range on an RN526x using a 10 gpbs NIC. Small file tramsfers averaged around 2.5 gbps
He doesn't say what drives he was using - they were whatever Netgear supplied. But they would have been mechanical, and not SSD.
The smallnetbuilder review measured 688 MB/s read and 372 MB/s sequential transfer speeds in their RN626x review

Then definitely worth doing if I can. I can live with pushing the limit by 2.5x. But adding a driver to the ReadyNAS kernel just isn't something I could have done even before Debian Jessie was archived, and I fear that Jessie and OS6 pre-date the emergence of 2.5/5Gbe as common and there are no drivers available, much less already present. But maybe Netgear used a chip set that can do 2.5Gbe and maybe even backported a driver.
My RD5200 does have a 10Gbe SFP+ card installed and, just for grins, I tried an SFP+ to RJ45 transceiver with "hidden" 2.5Gbe capability, and it flat didn't work. It would do 1 and 10, but not 2.5 or 5. But I really expected that since it's Intel X520 based and I was hoping for a miracle.
So, still hoping somebody can tell me what chip set Netgear used.
