Readyshare Speed
Yes, it is an old model - but I'm on Comcast in a small town. I have a 1TB SATA2 drive in a USB SATA3 housing with a USB 3.0 interface, connected to the C3000 with a USB 3.0 cable. I would expect to have file transfers through the Gigabit LAN run up to near the USB 2.0 speed of the modem USB interface, but instead, it runs at between 1 and 1.5MB/s, or 8 to 12 megabits per second, way below the capability of USB 2.0. What speed should I expect? How can I make it faster?
If they had implemented USB 2.0 High Speed, It would have been quite adequate for the home user - but apparently you need a newer model for that. Why did I have such an old model? It was what Comcast supplied me with - and will soon be gone.

Some USB 2.0 ports don'tsupport USB 3.0 device. Also with some USB 3.0 devices, may not be backwards comaptible with USB 2.0. You may need to find a USB 2.0 drive to test with.
Actually, downward compatibility is part of the USB standard - but you could be right; my old USB disk housing was USB 2.0, and that systtem worked better than this one with a newer and faster USB housing and HDD. But there is no problen with the USB 3.0 housing running on a USB 2.0 port - file trransfer runs at 200 mbps when I plug the new housing into a USB 2.0 port on the PC - that's fast enough for access to a backyp storage device. But the old USB unit only supported PATA drives, and I ran out of those. This one (LaCie) at least has air holes for cooling the drive. But I cannot find a solution for the 20X performance loss; file transfer running at 11 mbps (a number I've seen mentioned elsewhere in these many pages of Readyshare performance complaints) is a pathetic rate when you want to use it for an online backup drive. And I don't see any decent answers, other than yours - that the modem/router can't handle a USB 3.0 device that is running on 2.0 speeds to accomodate the Netgear unit. I don't think I will buy a Netgear uhit again.
It is what it is.
Yes USB is supposed to be backwards compatible however implementing it on either host or client device is up to the Mfr of each. I presume in this case since your working with a non USB 3.0 modem and the client device is 3.0 supporting, seems like this is the area of problem. Remember if the modem supports 2.0 then 2.0 would be a max USB connection on the modem. Weather or not the connected client device supports 3.0 and how it handles backwards compatbility will be up to that Mfr. It's possible the Mfr didn't fully support any backwards compabtility.
I ran in to a similar situation with a D-Link DWA-192 wireless adapter. It's a USB 3.0 connection adapter. However it would not work right on my Mac Book Pro 2008 that only supports 3.0. Even though 3.0 was supposed to be backwards compatible, the adapter has expectations of volatage needed for 3.0 operation which my Mac Book was not tuned to give. Installing on my Mac Mini 2012 works just fine since it supports USB 3.0.
So the modem is going what it can only do. How the device is handling the connetion is another problem which falls on the Mfr.I tend to not use USB on Routers or Modems for any file stroage solutions. Maybe some small stuff, however ideally to get best performances for storage solutions, NAS is the way to go. I got my first NAS several years ago and haven't looked back at USB since.
