Secure digital memory cards come in multiple capacity and performance options, and the ones that Silicon Power has just launched are among the best.
Called Superior UHS-1 (U3) SDHC/SDXC flash cards, they have read/write speeds of 90 MB/s and 45 MB/s, respectively.
That's Class 10 video recording performance and Speed Class 3 standard-ready (which actually needs a card to be just 30 MB/s fast, which the newcomers obviously exceed by a great deal).
You should make sure your DSLR, camera, HD camcorder, or 3D camera is UHS-I ready before you buy them though.
It would not be cool to pay dozens of dollars for 16/32 GB SDHC or 64 GB SDXC and find out it's useless to you. I’m not sure what the expected prices are though. Silicon Power didn't say in its press release.
