We will buy the BMPCC4k (This means 500GB/hour on a ssd), as we are a low/no-budget production, we can't have someone handling data.
I had the idea to use a rPI3+ to use for this. But I'm not sure if the rPI is able to handle this, he would be powered by a powerbank (20'000mAh).
When I insert the SSD, the hole SSD should be copied to a 4TB HDD.
So I have 4 questions:
Can the rPI Power an external HDD (2.5" 4TB) + external SSD (Samsung T5 500GB) form the USB Power Source
What's the average file transfer speed of the rPi from USB to USB?
Is there a software which allready can do this (Preferable with a data validation)
Which is the best OS to use for this? I'm only familiar with Raspbian, but can adapt.
