Michael, are you sure that isn't a typo? On the pictures we deal with, 50TB is less than 3 weeks of production. For us, 50TB total would be a very small show. And I'm not talking stereoscopic here...
Not a typo;-) Rather, let me put it this way:
How does one define "big" or "small?" It's relative to the individual, company, or project. In terms of motion picture negative, a terabyte is not a fixed unit of measurement because each camera captures a different gig-per-hour count. 50TBs with judicious shooting on Epic 5:1 is the equivalent of 105TBs of ArriRAW or 165TBs of CanonRAW. Clearly one is bigger than the other, but because it changes, it's difficult to clearly define what is "big" and what is "small." But perhaps we can agree on this: 50TBs and up has a more serious affect on the metrics of storage than under 50TBs. That's why I choose that number.
Because of this, I find that many companies rely heavily on LTO for VFX pulls & conform, especially when over 50TBs. And just to be clear to the other readers here: typical LTO data management is cheaper to store yet slower to retrieve than the spinning disk alternative, which is more expensive to store and faster to retrieve. The math in determining what is best for a project changes on every film because:
A) the datarate per-gig changes
B) the amount of VFX pulls and temp-conforms vs. full-conforms changes
C) the schedule of turnaround and delivery changes
D) the budget changes
I find that weighing the above 4 elements together helps determined the best way to move data around, and for this particular case study on Ender's Game, 96TBs spinning disks served as the best way to maintain optimal efficiency. In fact, a number of people in the cutting room and VFX vendor claimed this workflow as "the fastest turn-arounds in VFX data pulls we've ever experienced."
Do movies shoot more than 50TBs of data? Yes. Do they all move that data as efficiently as they could? Nope. Not even close.
