~30 mbyte/s is the perfect indication that he uses an USB 2 drive.

And with that its impossible to record in RGB colorspace with no compression and even fullHD.

A further problem I see here is the used filesystem on that drive. He wont record very long if he uses FAT32 which its filesize limit per file of 4 GB.

For the actual configuration (DXTory Codec, RGB, no compression, 30fps, 1920x1080)

your drive must be able to write 178 mbyte/s. Yours has 30. You see the problem? 

Interesting...  So the "RGB (True Quality)" setting is definitely 24-bit rather than 32?

"32-bit colors" has no more colors than 24-bit, the extra 8-bit are alpha, and GENERALLY in videocapture you don't need that.
