Re: alternatives to P2 cards?

Biggest minus I can see would be for solo shooters in the field like me. The battery life on these stores isn't going to cut it for me. If shooting 4 hours of footage, the firestore is likely to be switched on for 6-7. current firestores have a bat life of 90mins that means three to four batteries for a days shoot. thats 4 more to charge every night. Same for the P2 reader. I need a device that is going to run all day or at the very least a half day because if you run out of battery power your shoot is over. No HDD, no shoot.

P2 reader writes to HDD which means it needs to be flat and stationary during write down? Panasonic inform me that dumping and verifying is in real time or thereabouts so 30mins? That means no repo or re locates for 30 mins.

Obviously not as relevant for studio work.

The other negative is being fixed to the camera by a firewire cable. If Im shooting on the mountain in winter, that firestore is going to be tucked away in my jacket. How many times will I forget Im fixed to the camera?
