SD Express cards are removable storage cards that can fit in the same slot as other SD or microSD cards. But thanks to support for PCIe and NVMe interfaces, they can offer much higher data transfer speeds.

And now the SD Association has unveiled a new version of the SD specification which doubles the top speed of microSD Express cards, from 985MB/s to 1,969MB/s (or nearly 2GB/s if you care to round up). Full-sized SD cards support even higher speeds up to 4GB/s, but who has room for a postage stamp-sized card these days?

microSD Express Doubles Speeds, New SD Express Speed Classes Introduced [Press release]

The SD 9.1 specification brings support for microSD Express cards with speeds up to 2GB/s, or twice the previous top speed introduced in the SD 9.1 spec. It does this via a PCIe Gen4 x1 lane. The SD Association has also unveiled four new SD Express classes with minimum speeds ranging from 150 MB/s to 600 MB/s. You can find more details in the SD Association’s press release or white paper.

  1. Typo:
    “1,969MB/s (or nearly 2MB/s if you care to round up)”

    Meanwhile, UHS-II micro-SD cards/readers are rare and I haven’t personally seen a UHS-III micro-SD card reader. If you find one, it’s very expensive. How long have these standards been around?

    1. UHS II was released in 2011 and III in 2017. I tend not to use them, but I also don’t record much video. In most of my use cases for SD cards, capacity ends up being more important than transfer speed.

    2. I use my SD card in my handheld PCs as additional main storage and would love to see at least these older standards being implemented. Let alone this new one. Hopefully it becomes more common so prices go down too.

      The current speeds in most devices/cards have not kept up with the capacity increases making my use cases for these cards fairly painful.

    3. I’ve been wondering the same. SD Express and Micro SD Express have been around respectively since 2018 and 2019. I can only suppose that they’re releasing this stuff for a small userbase of professionals, but I’m not even sure whether that’s actually the case.

    4. I definitely want the speeds to increase. I feel the speed of actual cards generally has not been keeping up with the capacity increases. At least for my use cases.

    5. Maybe we can hope the gaming handheld space becomes a large enough market to target for higher SD card speeds where many opt to use SD cards over upgrading the SSD. Install times slow to a crawl because of how slow the IO is where it’s more of a bottleneck than your download speed. When you buy a game, you usually want to play as soon as possible.

      I believe the ROG Ally is currently the only one with a UHS-II micro-SD card reader. Although I’m not sure if the earlier reader issues ever got resolved.
