I'm editing a feature in october and need to get an external raid for storage what should I go for? They are shooting on the Sony xdecam ex and the Panasonic hvx 200 both using the 16gb cards they want storage on set and also I want a raid system for editing at speed and another for backing up. It's a 17 day shoot shooting two cameras.

So I want to know what sizes to go for and if anyone is using a raid tower. Also the costing - is it simpler to go for 2 esata 2gb raid externals or do I go for a tower with multi bays?
