Storage for Xavier NX developer kit

I just flash JetPack 4.4.1 to micro SD card for Xavier NX.
Now, the board has a poor storage, only around 1.5 GB.

How to manage storage in Xavier NX?
My micro SD card has 16 GB storage.

Thanks.

16GB is not enough to do sth on the Xavier NX, IMO.
You may use more bigger SD, mount NFS, or attach an USB storage.

And, refer below;

I see.
Ok, thank you so much.
