Re: why when i use gnuradio for USRP with UHD for high sample rate record file is not work

Well if you're recording complex float samples, that's 8 bytes each. At 60msps that's 480Mbyte/second. Not too many disk subsystems can keep up at that rate. 

You might try short recordings into a RAM disk filesystem.

I use a USRP x300, when i want to use uhd and file sink in gnuradio , for high sample rate like 60M or 80M gnuradio can not record file.Gnuradio print some character on log: i want to record a sample not any other thing.
Is there any way that i can record with high sample rate in gnuradio?
