Great! Now I can add more fast storage to my Samsung Phone that I bought during the past 4 years…oh wait
That’s interesting, but it will be bottlenecked in 95% of the cases right now by the connecting hardware, right?
Yeah, it can’t even use the higher speeds offered by uhs2/3 since the additional contacts are pcie, instead of the uhs2/3 design. They’ll fall back to uhs1/v90 speeds which are like 10% of the max rated output for the card.
They already make SD cards that can go 800MB/s but for the larger form factor and mostly used on DSLR cameras. The manufacturers will need to start implementing this new cards to our newest gadgets.
The cards that full frame cameras use to hit 800mbps are CF not SD. Functionally very similar, but you can’t just pop it in your laptop. You need an external reader. The nice thing about SD catching up to the CF spec is backwards compatibility. You can take your 800mbps SD Express and throw it in your laptop’s SD card slot and use it, even if it’s only at 100mbps because the laptop still uses an old SD version. No such luck with CF Express unless they can convince people to build CF ports into laptops and phones (though SD is just about dead in phones).
