But if they decide to use a memory card for holding the 8k files ? From now, til 4k get some adoption , til 8k, there should be at least 10 years in the process. |
I doubt that SD cards will ever be as efficient price wise as a disk. You don't have the overhead of circuitry with a disk.
I imagine that at some point the disk will be stationary and the laser will be the part that moves by mirrors.
Combine http://www.dailytech.com/Scientists+Create+360+TB+Superman+Crystal+Discs/article31933.htm with http://www.iflscience.com/technology/worlds-fastest-camera-takes-44-trillion-frames-second, direct a laser beam into a cube and analyze the light that comes out to retrieve your data.
Although I see optical holographic storage is already old news

Maybe SD cards based on that technique will be the future.
