10GbE pcie in 5,1 under High Sierra

If you're running at least High Sierra, this is the best card you can get if you want 10GBase-T for a small price. No drivers required and basically no downsides.
The first batch supposedly had some issues for some people, but revision "B" seems to be solid.

Great card. We also use the TB3 version of this with our video editors on maxed out iMacs, also excellent.
All depends on the disks feeding it. A modern PCIe SSD or SSD RAID 0 array for example should be able to saturate 10GbE.
Yes on sequential read, not on the write.

Not really. If you had two computers, each with a 10GbE card and an EVO 970 your transfer rate would be limited to the max sequential write of the SSD. On an EVO 970 it is not great.
What would be good for a NAS with a 10GbE connection then? 2x 2.5" sata3 SSDs on RAID0?
Best to browse the Synology site and look at the performance graphs.
RAID 0 gives you no resiliency. One drive fails and you lose everything.
A good compromise for increased reads and writes is RAID10.
I personally tend to use RAID 6 though and eat the poor write speed in favour of increased storage and resiliency.

Max sequential under sustained write for the 970 Evo is anywhere between 700 and 900MB/s, so yes it will saturate the 10GbE link.
Edit: it all depends on the drive size 256/512GB won't saturate but the 1/2TB will

QNAP makes good stuff too. Many models have an M.2 slot for an SSD cache in front of the spinning RAID.

True, but I've always thought that Synology make the better software of the two.
Both brands do M.2 and 10GbE these days.
I know it will give me x2 speed but will RAID10 2.5" SSD's saturate the speed of 10GbE. I imagine it would be close to 900MB/s
All depends on the number of disks in your RAID10 array, but I’d expect it would be close. The more disks the faster it will be.
4x 2.5” SSD’s as RAID10
What is the true real world performance of 10GbE with data transfer? Assuming the drives on both machines are fast enough and not throttling.
I get 780MB/s on a usb 3.1 external caddy with a 970 pro. That’s a 10Gbs connection too

An SSD RAID would be much faster. I have traditional HDDs in a RAID 5 connected to the Sonnet 10G. 500+ MB/s write is pretty good. 200+ MB/s read is on the slow side, but still more than twice faster than an HDD.

I upgraded to 10.14.5 beta and now getting much faster speed with the Sonnet 10G PCIe card.
EDIT: I upgraded from High Sierra.

I'm getting 504MB/s write and 304MB/s read
going from:
10.14.3 - 2018 Mac Mini
to
10.13.6 - 5,1 Mac Pro Sonnet Presto Solo 10GBASE-T in slot-4. Report says it has negociated a 4x 5.0 GT/s link speed
Both Machines have PCIe SSD's cabable of over 1GB/s
