In a press release issued Tuesday, the association announced that, thanks to new support for PCIe 4.0, transfer speeds for SD Express cards will now top out at just four gigabytes per second (3940 MBps to be exact) the SD 8.0 Specification. That's about four times the speed you get from the current SD Express card (985 MBps) and a huge jump from the fastest UHS-III SD cards of today (624 MBps).
However, when using PCIe 3, which is still twice the speed of today's fastest SD cards, that top-end figure for new SD Express cards will require a card reader that supports two PCIe 4 lanes, or else transfer speeds will be cut in half to about 2 GBps (1920 MBps). In addition, the SD Association says that SD Express will be available in a range of card sizes including SDHC, SDXC, and SDUC.
The way in which new SD Express cards achieve these speeds is through a new pin layout at the back of the cards that can use single or double PCIe 4 lanes. But perhaps more importantly, like previous versions of the official SD spec, SD 8.0 cards will also be backward compatible with older card readers, you'll just not get their full listed transfer speeds.
The reason why this is important is that with the rise of 4K and 8K TVs and phones and cameras capable of capturing photos and videos in higher resolutions and bit rates than ever before, it is becoming increasingly important to have removable storage that has sufficient capacity and sufficient transfer speeds to store all those data properly.
The same is true for gadgets like the Nintendo Switch, which by tacking on a separate microSD card can bolster its paltry 32 GB of onboard storage. The new SD 8.0 Spec could pave the way for faster loading times on future game consoles that support external SD card storage, by increasing the transfer speeds of SD cards.
Even now, if you don't have the right camera card, the camera may not allow you to record videos at the quality of your desired image, which means it's critical that you pay attention to the specs listed on the SD card.
Unfortunately, while today the SD Association has officially announced SD Spec 8.0, cards that actually support the new standard may not be available for a while (probably earliest in late 2020), as it will take some time for SD card makers like Samsung , Sony, and others to implement SD 8.0 into new SD Express Cards.
