Re: [Discuss-gnuradio] Higher sample rate

[Garver, Paul W]

You might try specrec in the gr-analysis module. It is optimized for fast writes but is Linux only. We routinely do 2.5 minute records at 25 MSPS sc16 format (100 Mbytes/sec sustained) with a b200 without typically dropping any samples. As mentioned, your hardware makes a big difference. We do this on a Samsung 840 EVO SSD and a generic dell laptop, so no raid required. Hope this helps.
