Has anyone gotten any storage attached to the RT6600ax that works at faster than USB 2 speeds? I thought it was supposed to have a USB 3.1 GEN 2 10gbps port? I can't seem to make it go faster than USB 2 speeds.

So first I tried the drives plugged straight into the RT6600ax USB port:
The drives are:



These drives mount up no problem. You can install threat prevention etc. with no problems. However, performance is lame.

They should read/write around 1000MB/s or 400MB/s, but I could only get the drives to read/write files at around 85MB/second (by copying/pasting some large files I transferred on to the drives).

So I decided to try some HUBs to see if they would still work (because at some point I would like to also use a second ISP with the router and still have Threat Prevention/storage).
The HUBs I tried are:




All 3 of them worked, and all the drives still mounted. The speed was still limited to the 85MB/second USB 2 speeds. However, I did notice in ControlPanel>Device that in addition ot listing the drives I had plugged in, and now showing the HUB, it would show a HUB 3.x AND a HUB 2.0. So clearly the Synology router seems to be negotiating DOWN to a USB 2.0 hub.

So that's where I am. There seems to no way to go faster than USB2 speeds. Has anyone gotten faster performance? If so how? Maybe some blessed storage device and/or hubs?

Thanks for any help!

Wifi 2.4 active?
The theoretical speed of USB 2.0 is 53MB/s so if you are getting more than that then it does work on some USB 3 standards.

Youre right. But wow is that pathetic throughput! That's only about 680Mbps throughput when we should be getting 10Gbps theoretical throughput and the devices are rated (and I have tested, they do get near the 1000MB/sec and 400MB/sec read/write when connected to a laptop).

My test for throughput is I coped a folder full of 400MB videos, about 4.5GB of it, and just copy/paste that folder through the FileStation app.

There is something killing performance. I get it might not be as fast as a full desktop or laptop, but you would think it would be at least half or even quarter the speed. This is like only 8.5% of the speed. What is interesting is both devices have very different top speeds, but both seem to be limited to the same top speed throughput. I wonder what's going on here.
