HMC 150 for Documentary in Challenging Conditions?

I've just been brought on the shoot a 3 month long form documentary in difficult and challenging conditions in Haiti.

I have never worked with the HMC 150 or with any solid state camera, however I have shot with the all the DVX models in different conditions and and they have never caused me any problems.

I wondering if anybody has worked with the HMC150 in similar conditions?

If so how has the camera handled and what challenges has the SD card work flow if any caused you in the field. I'm a bit old school and worry about the durability the SD cards as well and how to successfully and securely back up and archive shot material in challenging conditions. The idea of carrying a lap-top and external drives in the field worries me...

Any input, tips, and resources or other camera options would be greatly appreciated.

Thanks, BErnard
