Drobo is proprietary... if your drobo dead, all your data will be gone. Good luck that happen wihtin warranty period. Then tech support might help you get your data back. Otherwise, it's a gone..
Mcgeedigital is right too! it's for backup purpose. Their speed is too slow to be used as realtime editing purpose. They have a new DroboPro using iSCSI (ethernet connection). It is supposed to be faster.. but I don't have any luck having it setup to work well. It's slower than my internal RAID-0.
