Sure, Toshiba just got around to launching its super-fast SDHC UHS-I cards with read speeds up to 95MB/s yesterday. But that’s nothing. The SD Association has approved a new standard that could lead to flash memory cards with read speeds up to 300MBps.

The new SD cards will be the same size as current SDHC cards, but they’ll feature a new dual-row pin design. The new SD card readers will be backward compatible, letting you read older SD, SDHC, and SDXC memoy cards, but it sounds like you’ll need a reader with a new interface to use the new superfast SD cards.

The new design is part of the new SD 4.0 specification which will be finalized in early 2011.

  1. Sigh. I hope you realize that there is a difference of nearly an order of magnitude between “b” and “B”! 300Mbps is 300 megaBITS per second. If you mean to say 300 megaBYTES per second (which is what the press release says), it should be 300MBps (or 300MB/s, as more often than not, “ps” is used instead of “/s” when talking bits).

    1. Indeed. 300 Mbps = 30 MB/s < 95 MB/s. Makes this entire post kinda silly.

    2. I’m surprised how tech bloggers have very little actual technical knowledge.
