RN528X ethernet bandwidth
I would like to speed up transferring data to and from my RN528X and note that it has two 10Gbe port. I currently have it linked to my LAN via a 1gigabit switch so can't get more than 112 Bps transf...
Yes, you could consider creating a LAG (LACP or static) from two Ethernet ports on your NAS. This requires a configureable switch at least, to configure the two ports as a static LAG or LACP LAG - otherwise there willl be some massive loop condition on your network.

Many thanks
I recently did exactly what you want to do and did essentially what StephenB suggests. In my case, the NAS is a rack mount one with SFP+ ports, so the switch was even cheaper with 4 2.5GBE max multi-gig and two 10GBE SFP+ ports. I got significantly better performance, but didn't realize the full potential of the 2.5GBE, especially on writes, because the NAS can't keep up, so going with 10GBE on the PC side is probably a waste.
Depends on your storage media and RAID config. With SSD's, I'm seeing max writes at ~620 MB/s in RAID 6, and when I briefly tried RAID 10, I was getting about 850-900 MB/s writes. That's 2x to 3x what a 2.5GbE port can achieve. I had a weird crash during the SSD RAID 10 build - which was probably my fault as I was running file transfers while it was doing its first-time resyncing (too impatient!!! 🙂) - so I chickened out and went back to RAID 6. Even using spinning HDD's in RAID 10, peak write speeds should exceed 500 MB/s.
Read speeds also deserve consideration. Even with RAID 6, with SSD's the 10GbE link is fully saturated on reads when moving files from the NAS to my NVMe drive on the desktops or laptop. That's 4x the speed a 2.5GbE port can achieve. If reads are important to your workflow, something to consider. FWIW, the ReadyNAS performance report also achieved saturated 10GbE using 1TB HDD's in RAID 6.
Today it's pretty easy to find inexpensive combo switches that are primarily 2.5GbE with one or two 10 GbE ports. The proliferation of 2.5GbE (it's in 95% of new motherboards now) is understandable - lower power, less expensive componentry, and less expensive to implement on a PCB (10GbE can be a PITA w/ RF shielding, finicky trace layout, etc.). Good enough for most needs, but if you're sitting on a NAS with 10GbE ports, seems a waste not to make full use of them if your config can make use of them.
