AX56U USB3 Transfer Speeds


New Around Here
Here's some info on the AX56U's USB3 transfer speeds. Sadly Revision 11 of SNB's Router Charts no longer measures this info.

Last night I bought an ASUS RT-AX56U wireless router, primarily because my Netgear R6400(v1) had crappy USB3 transfer speeds of around 30MB/s.

My testing shows that the AX56U fares much better: ~100MB/s reads and ~60MB/s writes.

Testing setup: I'm using a Samsung T7 external NVMe SSD, capable of sequential reads and writes of around 1,000MB/s. The drive is configured with GPT and an NTFS volume. I'm copying large video files to/from a Windows 11 PC, using a SMB (Samba) network share I created on the AX56U. The PC and the router are connected by 1Gb Ethernet.

The read speed is fantastic, pretty much saturating the 1Gb Ethernet link. But I'm honestly a bit disappointed by the write speeds. I'd been hoping for more thanks to the 1.5GHz quad-core CPU in the AX56U.

Still, for an £80 router, I really can't complain. It's a big upgrade from my old R6400.

That did help a little, thanks. Now getting 110MB/s read and 65MB/s write with the UPnP server off. Still a little on the low side, but I won't lose sleep over it. The other day I put Merlin on there too, which may have helped.

Thanks for your suggestion.
