20 MHz @16bps is 80 MB/s right? That's just not going to work on a laptop hard drive without doing some major compression. I wrote a gzip_file_sink at some point in the past but the libz compression was too slow to even keep up with 8 MHz @ 16bps. You could try looking for an alternate compression algorithm. I hear LZO is faster for instance. IMO the best option for a laptop is an SSD. I do get about ~80 MB/s sequential write with my Intel SSD. But 160 GB isn't a lot if you're going to be doing 20 MHz sampling!
