As someone mentioned, if you resize it it's no longer a "RAW" file
as it didn't come from the camera. If you want something smaller, try
using the losslessly-compressed version and take a picture that has no
significant information... like a white piece of paper. Those types of
shots compress very well and depending on how smart the algorithms are it
could reduce the size a lot.
