FRAPS is not uncompressed, or else you would need an SSD for recording. And to the OP, 4GB/min is approximately what you will see if you take an average when recording 1080p 60fps. But the bit rate will change depending on how much motion, or how much of a change there is in each frame, as well as the level of detail and the FPS recorded at.

Are you wanting to record lossless? If so, then I would use Lagarith with Dxtory because IIRC it has the best compression of any lossless encoder. However, if it is slowing down your gaming due to it's CPU usage, then you should use the UT Video encoder since it is "quicker", but doesn't compress quite as much.
In general, I wouldn't recommend FRAPS unless you really need the "Loop buffer length X seconds" feature.
Another alternative to a HDD for recording would be a RAM drive. But it only works well if you have at least 12-16GiB of RAM(to create a RAM drive of 8GB or greater), and if you're only recording clips. Basically, you record to your RAM drive, then when its been 3min or when you die, you stop recording, and delete the recorded footage, then start recording again. I'm sure there is a way to automatically delete the contents of the RAM drive at the press of a button, or key combo. Using a RAM drive to record is where FRAPS shines, since it can cache any length of recorded footage you choose(I use 120s). And when you want to save what happened in the last X seconds, you press record twice, or once if you want to continue recording. The only downside to using FRAPS to record is that it will try to cap your FPS at a multiple of your recording FPS(e.g. I record with 30FPS, so FRAPS will try to lock my game FPS at 30, 60[VSync on], or 90[VSync off]). So make sure you can hold above 60FPS with your graphics card, or settings.
Here is how to use that FRAPS feature: (Click to show)
FRAPS has the ability to constantly cache up to 4GB of gameplay(AFAIK, possibly more, but haven't tried/needed to). This avoids having to constantly record useless footage and fill up your hard drive.
You can do this by first setting your Loop buffer length to as many seconds that you would like to cache. Pic: http://img.techpowerup.org/120112/Capture348.png
Now once your in game and ready to record, press and hold the Video Capture Hotkey until your FPS overlay turns pink(~3s).
FRAPS will now have the last X seconds of gameplay cached, so if you get a nice clip, you can press the Video Capture Hotkey(FPS overlay turns red, from pink), and it will be recorded, as well as everything afterwards until you stop recording.
The split files are due to a limitation of AVI 1.0.
