This has not overly much to do with that being done with GNU Radio: If
your machine is fast enough, yes. If not, no.
Instead of the overhead of a file on a RAM disk, simply use a vector
sink, at least if you're using modern GNU Radio (3.8): Use the "reserve
memory" field with enough space to record all you wanted to record to
make sure your program doesn't need to shuffle data at runtime.
Also, setting larger output buffers in the GNU Radio blocks can help,
too, if you don't need low latency (which you don't need at all, if
you're just recording). Try setting "2**24" in the min output buffer
setting in your USRP source's "advanced" tab.
