Kingston introduces the fastest SD cards in the world - SDHC UHS-1 UltimateXX

While the latest standard for SD cards (UHS-II) was just introduced by the Secure Digital (SD) Association over at CES 2011, Kingston, one of the premier flash storage and memory manufacturers in the world, is making the most of the SDHC UHS-I format, by introducing its flagship SDHC UHS-I UltimateXX memory cards. Before you go thinking that they are behind the curve however, note devices that accept UHS-I rated memory cards are only now starting to hit the market, as is the case with most standards.


[RELATED_ARTICLE]Kingston calls these the highest speed class available today, nearly three times as fast as the older Class 10 standard, with up to 60MB/sec. read speeds, and up to 35MB/sec. write speeds. The performance of these SDHC UHS-I memory cards is optimized when paired with a UHS-I device, although they are backwards compatible with Class 4, 6 and 10 equipment.

Nathan Su from Kingston spoke about release of these new memory cards: “Being a member of the SD Association enhances our ability to bring new technology to market. As the devices that support SDHC UHS-I become prevalent, our UltimateXX cards are at the ready.”

The UltimateXX product line will offer capacities of 8GB, 16GB and 32GB. Kingston memory cards are backed by a life-time warranty. Find the complete specifications below:
