Ready NAS 102, What is the maximum throughput possible with this NAS?
I know this subject has been discussed before, but I haven't found a posting that really answers the question. I realize there are many, many factors that affect what one actually achieves but I woul...

Must be a typo here - I'm guessing you meant to type 117 MBps.

The ReadyNAS has two WD RED WD40EFRX, 4 TB, 3.5" SATA 6Gb/s, 5400 RPM disks. I am running firmware: 6.10.8.
I have 1Gb throughout my network and I've configured the Cisco Gb Switch and all nodes for jumbo frames.
With this setup, The ReadyNAS is only able to achieve 123 Mbps (15.38 MBps) read and 132 Mbps () write. In 2016, before the 6.4.2 update I was able to get 63.5 MB/s or 53% of network bandwidth of 1Gbps.
You won't get 100 MBps+ from the RN102. But you should be getting more than 15. Have you ever run the maintenance functions (balance and defrag in particular)? It might also be useful to run the disk test (and also look for disk-related errors in the log zip file).
Assuming the disks are healthy, I suggest doing a factory default, and then restoring the files from backup. I think that will restore the 2016 performance.
Thank you for the quick reply! Yes, that was a typo.
If I could get back to about the 50-60MB/s I'd be happy.
I have started running some of those tests. The disk status on the main volume screen says the array is healthy. A look at the Status under the performance tab, and the popup if you hover over the green dots says the disks are fine, no errors at all. The Disk Test returned a disk failure alert, but it wasn't specific about what the issue is. I have not received an email failure notification. The Balance test completed successfully. I haven't run the Scrub or Defrag tools yet. Those could take a huge while.
I'm in the process of backing up the data now but that's also going to take a huge while at 15 MB/s. I'll do the reset when the backup is finished.

The log zip should tell you. Look in disk_info.log for smart errors, and in system.log and kernel.log for other disk errors.
Well, I looked through the log files and did not find anything about any problem with the disks. A look at the SMART data indicates zero errors on one disk and just now, ATA error count: 2 on the other.
I have backed up the entire array, then I did a Factory Reset. When done, I did a test copy of a large test file. The transfer rate is still only able to achieve about 115 Mb/s Then I decided to downgrade the firmware to 6.10.4. That test is running now an there's no improvement. I may go back even further and see if I can find the release that gets me at least 50MB/s.
I wonder if this is Netgear's way of forcing us to get a new NAS. I, for one, won't get another Netgear NAS. As I stated, I have a Synology NAS that's working gangbusters.
Any suggestions are appreciated.
I just measured my own RN102 - I get about 70 MB/s when writing a large file to the NAS, and about 60 MB/s when reading it from the NAS. Firmware is 6.10.8. RAID is 2x1TB RAID-1 (X-RAID) using Ironwolf disks.
