How to save data for a device working at a high sampling rate?

I'm new for signal acquisition, I'm working with USB-6363, which has a very high maximum sampling rate of 2MS/s.

If I want to run the DAQ at 2MS/s, the data that it collects is extremely large, especially if I run it for a long time.

I just wonder how people normally store such a large amount of data. Should I learn how to use database?

Use binary files like TDMS.

DAQmx has a built-in TDMS logging feature for high-speed streaming. See NI-DAQmx High-Speed Streaming to Disk
