Actually, that's not fair, it says the card only supports 30MB/s constant speed, so the video must be compressed to work. Still, even then you're talking 9/18/36 minutes per card assuming max constant speed bitrate.So, if you're buying this for 4k video, assuming 700MB/second uncompressed video, you can have either 23, 46, or 93 SECONDS of video per card? Better get that shot in fast, no space for a retake!
Actually, feature films are (were?) shot using film capable of about 4 minutes recording length, if I'm not mistaken...Well if the burst write speed is in the 200 MB/s range, it's an awesome card for the very high end SLR cameras. As for 4K recording, that's going to have to be pretty short and compressed.
Agreed, my guess is cost of Fiber vs Copper. If you look at Wifi it's gone up really fast and the prices have dropped fairly quickly as well when you compare 802.11 G to AC. No "medium" required.First you need to get 10 GbE to realistic consumer prices. I don't really see what the holdup is. I've had gigabit Ethernet for over a decade now in my home computers. Gigabit switchs have been dirt cheap for quite a while now. It seems that the steps from 10 to 100 to 1000 where all quite quick. Then it just stalled.
