This 8K video demo is stupid. Lets assume a relatively modest 8bit per component RGB, a 7680x4320 frame is 132MB, at 24fps is 3.2GB/s. So in 1TB you can store

This 8K video demo is stupid. Lets assume a relatively modest 8bit per component RGB, a 7680x4320 frame is 132MB, at 24fps is 3.2GB/s. So in 1TB you can store 312 seconds aka 5 mins of video. You're going to have to top this up to play any more than 5 mins, which means writing to the SSD at 3.2 GB/s whilst you read from it. I do not believe even any NVMe SSDs are full duplex, so that's 6.4GB/sec, which the SSDs cannot provide. You can DMA to GPU memory at 10GB/sec, so the SSDs are of no benefit for video. No-one stores 8K data uncompressed anyway, so the CPU will need to read and decompress the data. Perhaps it's useful for faulting in megatextures for 3D scenes though.
