I've been using Linux since 1995, and now I run 2 BBSs on it, on a si Banana Pi.
Seen these on sale. Have you run an RPi & a Banana as well? What's different & the same with the Banana...other than the cost? Know anyone who has/is running some of the other "Pi" boards?
Many of the Banana Pi boards (though not all) have a real ethernet
PHY and real SATA controllers. The Raspberry Pi family (more
generally, the broadcom SOCs they use) provide these functions via
a USB bridge, which means both network and storage bandwidth is
limited by the throughput of USB, which is well below what you can
do with real GigE and real SATA.
The Raspberry Pi 4 might have enough oomph that things are getting
reasonable on those boards, but if you care about "balance" between
computation and IO capacity, it's better to go with a machine that
has dedicated hardware.
"Balancing" IO and compute was a big part of what set workstation-class computers apart from PCs back in the 80s and 90s. It always amazed
me when people bought a "fast" Pentium with "lots" of RAM (for the
time) and then hobbled it with a PATA IDE disk....
Even today, we see this often with people opting for a "faster"
processor but not balancing that with the memory subsystem and
cache layer. Why pay a few hundred bucks more for a faster CPU
that you can't feed fast enough to run your actual workload faster?
