If you are on Linux you could just create a file in tmpfs (i.e. RAM).
Use a File Sink with a file in "/dev/shm" for instance (see "man mount"
to configure tmpfs).
Of course you then probably need a lot of RAM (or can capture only small
durations). But it is much faster than disk I/O...

The problem is not the metadata, the problems is the sheer amount of
samples.

Hi,
Thanks for your reply.
Now that since metadata can't be saved to a file, how can we keep track
of timestamp of the received packets? I can use tag debug to display the
timestamps of received signal but when flowgraph starts demodulating
data it looses track of timestamp display on console
That might very well be the case:
20 MS/s of 32bit float complex would amount to 1.280 Gb/s writing
speed.

Hi all,
I have been trying to capture data as well as meta data in file meta
sink in GNURadio. When I run my gr-ieee802.11 receiver flowgraph with no
file meta sink, it captures the signal transmitted by a dedicated source
which is always turned on. However, when i just try to capture and stor
