I currently have a Raspberry Pi 2B+ which I have set up a Samba share on. I'm aware that both the ethernet and the USB share the same bus, which contributes to slow write speeds when transferring files across a network onto a USB attached device.
I was wondering if this has changed with any of the more recent versions of the Raspberry Pi?
The Raspberry PI 4B is very different to previous models of Pi, in terms of the limitations of the hardware. There is very much more IO bandwidth available: the gigabit ethernet is directly connected, and does not go via USB, so operates at full speed. The USB controller is external to the SoC and is connected via a PCIe link, so you get full USB 3.0 speeds. The addition of more memory, on the 2 and 4GB versions, is also extremely welcome.
Clearly if you are using the Pi 4B to talk to a Pi 2B then the speed is going to be contrained by the 2B, but when talking to PCs etc you should see much better performance with the 4B if you are moving a lot of data.
