True and 5 computers with nigh onto 40,000 high res photos,
programming...etc equates to about 6 Terabytes each.

Likewise. I have the fastest I could get but even at 100 feet signal is
poor. OTOH even with strong signals it's a long way from catching up to
the CAT 6 network.

True, but even at its best it comes no where near the wired gigabit
network. This is not a problem for uploading photos from point and
shoot or cell phone cameras, but with pro cameras, or one computer
talking to another it can be a real bottleneck. I try to keep two of
the computers backed up to two others as well as a rolling archive.
When storing images as jpgs it's surprising how many get corrupted each
month. NEFs and TIFFs don't seem to have that problem.
Most would not notice the difference but more than one BU at a time
(using switches) still brings things to a crawl.
It's amazing that when I turn the Wi-Fi on how many unsecured networks I
can see on the screen. If I know the people with the network, I explain
how open they are. Often behind that open network are open computers.
FTP mining ground heaven.
