I have a Linux based device which has network and USB, but write speed over the network is very slow. I'm wondering if a network storage device exists which allows write to a drive/share over the network, and reads of the devices/share over a USB connection? This would let me write files over the network faster.

There is no NAS device that I know of that will give you fast copy speed via a network port on the device. I think that most commercial NAS devices (that have USB on them) will give you copy speeds of between 2.5MB/s to 10MB/s. I haven't heard of anything that would give you anything faster than that. If there was , I would like to know.
I think what people do in this case is find a Nettop PC or a cheap PC that has SATA drives on it. In that case, the PC motherboard has a wide transfer rate from the drives through the motherboard directly through the network adapter. So, in theory, you would get full network speed. On a old 100MB network, it would be many orders of magnitude faster than a standalone NAS device, which are usually constricted by the USB controller.
What kind of device do you have? We have a QNAP NAS and they have different versions with different processors and ram modules that have a fairly good performance.
