BinaryImport is complet unusable for this task.
I tryed the same with similar data sets and run
out of kernel memory (with 1.5 GByte RAM) & 3GB swap).
The WRI support respondet, that "BinaryImport" is
not for reading *large* binary data.
You can have the beta version of MathGL3d 3.1 that
has an extra C-Function for that task.
Since it also include excelent volume rendering functions
and a native format for reading and writing compressed
volume data files you should use MathGL3d 3.1b.
Contact me direct if you wish to "beta test" the new
