Anyone have experience with streaming 100+ MSPS of 16 bit IQ data through a compression tool and then to disk? I'd like to be able to take really wide band snaps for several minutes. Currently that would take up 16 * 2 * SAMP_RATE bits per second. So, for 200 MSPS that would end up being 800 MBytes/s. That rate eats up a hard drive pretty quickly. Running it through gzip by way of pigz was my first thought, but even on an 8 core Intel machine pigz just can't keep up. I can sustain maybe 300 MBytes/s but that's it. And I know it's not a hard disk limitation as the M.2 drive I am using can easily sustain 800 MBytes/s of uncompressed data.
Thoughts? Thank you! -Dave
