Let's say I wanted to watch a large video from this SD card, wouldn't the transfer from SD card to display be slowed down by the bus between the board to the display?
Similarly, if I wanted to transfer the same video directly from the SD card through the bus, then through a network interface over a network to another computer, wouldn't the write speed be slowed be all those components in the middle?
I don't understand the write speed at 880 MB/s if it'll inevitably be slowed by many other slower components.
- chatmasta 9y agoYou could levy the same criticism against any external component. It should go without saying that you won’t realize speed gains by upgrading your SD card if the SD card is not the bottleneck. That said, 800mbps is plenty fast for watching video, as long as each second of the video is less than 800mb. Or maybe I’m misunderstanding you?

- penagwin 9y agoThose "parts in the middle" are the PCIE lanes, which is the fastest bus for peripherals straight to the CPU. Yes it will technically slow them down - although rarely is it the bottleneck. To my knowledge, there isn't a faster bus on the whole system.
