I think you should first get an estimate of how much footage they expect to shoot. And what resolution, frame rate and compression settings the DP wants to use since this will all affect how much data you will generate. Also, how many cameras they will use. Then use an app like Red Tools to figure out how much storage you actually need. Normally, you would do a minimum of two simultaneous backups with a third backup done offsite for extra security.
Ideally, you want to only use USB3, Thunderbolt, or eSATA for fast transfers. FireWire800 is really very slow and will bog you down. If you can, get a computer system, hard drives, and reader that can all do USB3 or Thunderbolt, it should be 2-3x faster. I would usually never start a multi-day Red project with less than 2TB of storage per drive. You never want to fill the drives completely since they tend to slow way down once they get filled past 50% of capacity. When in doubt, ask production to order more.
Also, download the free Redcine-X and Davinci Resolve Lite applications and get familiar with them so that you can view the downloaded footage. https://www.red.com/...6465a4b46002ddchttps://support.red....7-REDCINE-X-PROhttps://www.blackmag.../davinciresolve
You'll also want to download an app for downloading with checksums if you're not computer savvy and able to generate checksums yourself. I recommend Shotput Pro since it's relatively cheap and works for all kinds of media. http://www.imaginepr...o&products_id=2
* The MD5 checksums would be standard, although if you really get bogged down then the down and dirty method to speed things up is to just do drag and drop and avoid checksums all together. This brings up all sorts of liability issues since at least with a checksum you have a piece of paper that you can wave around when something goes wrong. But really, that should never happen since you'll be expected to not only report immediately any copy errors reported by the software, but also to visually verify all the shots yourself in Redcine or Resolve and report any errors that the software didn't catch.
