  What Hard Drive to Get for 4K Editing?

  Posted by Stefan Ilea on September 1, 2015 at 8:07 pm

  Based on this page Avid spec page:

  https://avid.force.com/pkb/articles/en_US/white_paper/DNxHR-Codec-Bandwidth-Specifications

  DNxHR HQ Tranfer rate = 88.88 MB/s = 88.88 Mega Bytes/second

  From my calculations, is it correct that any of these drives below would allow me to edit smoothly in 4k?

  Thanks for any more help!!!!

  RAW FOOTAGE CALC

  C4K @ 24p, 100 Mbit/s
  100 Mbit/s x 1 byte/8bit = 12.5 MB/s
  12.5 MB/s x 60 s/min = 750 MB/min
  750 MB/min x 60 min/hr x 1GB/1000MB = 45 GB/hr

  Estimated RAW FOOTAGE Space Requirement

  2 hr (final feature length) x 10 (estimated shot footage) = 20 hours x 45 GB/hr = 900 GB

  Transcoded Footage

  DNxHR HQ Transfer Rate: 88.88 MB/s
  88.88 MB/s x 60 s/min x 60 min/hr/ x 1GB/1000 MB = 319.97 GB/hr
  319.97 GB/hr x 20 hours x 1TB/1000GB = 6.4 TB
