Hello,
Thanks. This is definitely useful to know.
What is the speed and performance of the builtin wireless card on the 3B+?
Thanks.
Dave.

same hub, is a "SMSC LAN9514" if I understand correctly. In the pi 3b+
the capacity was increased for the eternet, but only to 300 m, not 1000

See https://www.raspberrypi.org/forums/viewtopic.php?f=2&t=4592 ;(in
english) and

that is a good explanation but in spanish.

Hi,===========================================================
Clarification, Ben you indicated that USB and ethernet go with the
same port. The Pi I have has four USB2 ports and a separate ethernet
port. That being the case does your statement still apply? I do agree
with you that USB2 is going to be a bottleneck. Is there a Pi now or
in the future that would have USB3 ports?
Thanks.
Dave.

the same USB port as all the other ones on the Pi. Personally I'd do
some benchmarks with the drive connected to your router, switch it
over to the Pi, quickly set up a share, do the same benchmarks then
settle for the one that gives you the greater speed. I suspect that
USB 2 will be the bottleneck in this situation but I could be wrong.

Hello,===========================================================
Thanks for everyone's feedback.
Pranav, thanks for the reminder, I should have mentioned, the drive is
in a powered USB case, plug in to the wall, the other is the USB in to
the pi.
Both the Pi 3b+ and my router have USB 2 ports so I'm not going from
say USB3 to USB2 they both have the same kind of port, the Pi 3b+ has
a quad core and a gig of ram, the router has a single core 600 MHz and
only 256MB of ram.
Thanks.
Dave.

Hi David,===========================================================
I suspect you can do this. However, get hard drives that are in a
powered
case as the USB ports of the pi may not provide enough power.
