A typical concert produces over 14GB of audio data. That takes a while to transfer, even through Gigabit Ethernet.
Early in my search for a DAW system, I tried Audacity, but it muxes everything to a temp file, and so closing the recording takes 45 minutes for the laptop hard drive to export that temp file to 8 individual 24/96 files.
I have been using Vegas 4 on the Sony laptop for 8 years. I chose it because it writes the final files from the beginning of recording. Stopping and saving takes milliseconds. Cakewalk Sonar 7 also writes to direct files, no intermediate dump, so saving and shutting down is effectively instant. If the power fails, at least I have what was recorded up to the failure. With the other programs, it's difficult or impossible to recover the temp file and demux it.
Best solution might be to buy a bunch of 896 Original boxes and stick with what worked. Really frustrated that I can't get "old reliable" repaired anymore.
