I'm helping a friend to assess external storage options. We are hoping that a Lacie 2big will be fast enough to support a 4K final cut work flow. Can two spinning 7200RPM drives configured as RAID 0 even play back 4k ProRes raw?
I found an apple white paper which looks extremely informative -- can someone confirm that "Mbps" in this document refers to megaBITS per second? If so, we see these data rates for ProRes 4444 (no alpha):
24p 1697 mbps 212.125 MB/s 25p 1769 mbps 221.125 MB/s 30p 2121 mbps 265.125 MB/s 50p 3539 mbps 442.375 MB/s 60p 4242 mbps 530.25 MB/s
If I understand that white paper correctly, those data rates look pretty high for just two drives. Does anyone have any personal experience working with 4K ProRes RAW off a pair of spinning drives in RAID 0? Is this feasible? Or should we be looking at 4-drive or 5-drive units?
