R3D (and other compressed 4K) footage should be cool with a beefy processor. Uncompressed 4K (for example DPX, DNG, TIFF image sequences) needs some hardcore read performance speeds of 1-2 GB/s depending on the frame size.

If you’re working with compressed 4K stuff you’ll need a very beefy CPU or two and if you’re working with uncompressed 4K you’ll need a disk array that can read/write about 1-2 GB/s depending on the frame size. That is not a typo.
