So I'm in pre-production for my first feature film that will be shot using a Sony a7s II recording to Atomos Ninja Flame; 4K (2160p) DNxHD 220. I bought a high end PC rig couple weeks ago that will be able to handle the edit and colour grade that I will be doing in Premiere and DaVinci. It's a low budget independent feature, but it looks like I'll have to allocate $500-700 or the like for storage options in the budget.
Our default process thus far with short films has been the ol external USB 3 hard drives like Seagate and WD etc, and buying extras to store backups on.
I've never used RAID's before and have just started doing homework on them. Wondering if anyone with experience in RAID's could help me figure out which path to take. Our options seem to be choosing from RAID 1, 5 or 10 that include redundancies? I estimate we'll need at least 8TB minimum for principal footage, which means we'll need 16TB in total if we want to have one back up version of everything.
