Can anyone name a internet provider that will have the bandwidth to stream 8K content because I am not sure they exists except for certain Asian countries that have gigabit connections. So how would anyone get 8K content when many people do not even have a fast enough connection to stream 4K content.
If you're showing an 8K movie at 60 frames per second, with each 8K frame being about 332 Mbits, you need 1.9Gbit/s throughput using raw uncompressed format.
Current SSD technology delivers 6Gb/s at SATA3 speeds, so there's more than enough speed.
One movie at 60 fps assuming an average of 130 minutes would need about 15,000,000 Gbits storage area or 2,000,000 Gbytes to store in raw format. Since nothing is stored in raw format, you want to use one of the common video encoders currently being used for UHD content - H.265. That provides you with compression of about 70% on average for movie content without losing quality as shown in this paper
So that takes you from the horrific (2 million Gbytes) to the expensive ( 600k Gbytes) storage needed. Or 600 Terabytes... or 0.6 Petabytes. For a 24 fps movie, it would be 240 Terabytes.
Anyways, it's a lot. Drives that size will probably be available in the far future... like in about five years or so. Samsung has a 16 TB SSD now, I could see that growing in the 100's in a reasonable time.
Streaming would need a bandwidth of about 0.5 Gbit/s for an 8K movie at 60 fps if you use H.265 compression. About half that for a 24 fps 8K movie.
Basically it's beyond the US reach as far as our internet infrastructure (except for google fiber and other local services like it), but not past Japan's or Korea's. Storage is probably a bit further out, but not that much if we base it by previous growth in size of drives. As far as SSD speed, the current ones can easily handle the demands of 8K.
