Depending on what you want to do the "expensive"
route is a card with more than one controller on it. By controller
I mean a device that speaks to the computer busses directly say
via a PCIe socket. I do not mean a controller followed by a hub to
split it into for USB 3 sockets. The four controller card I have
(closer to $300 than $100) has four controllers so I could in
theory have four USB 3.1 transfers going on simultaneously at very
near the peak speed capability of the four USB 3.1 busses added
together. The limit would be the PCIe bus I believe. With that
running a pair of AirSpy R2 devices at full 10 MHz is easy. If
OTHER aspects of the computer could support it a pair of R888s at
full 64 (or so) MHz wide sets of samples could be processed at the
same time. (That might be sufficient to get my computer to roll
over and die, though. If not I have disks I could put on the other
two USB ports to capture the data. I don't think that would work,
especially after the speculative execution slowdowns in the
current INTEL kernel downgrades due to security vulnerabilities.)
