The SD Association this week unveiled the SD Specification 5.1, which will allow memory cards to better run applications.
SD Specification 5.1 creates the new Application Performance Class so cards can store and run apps, as well as manage large stores of media, such as music, movies, and photos, quicker. Along with the new spec, the SD Association is debuting a new symbol for Application Performance Class cards so consumers can easily identify them.
“With its consumer-friendly symbol, App Performance Class eliminates buyers’ frustration with identifying app-running compatibility on their Android devices and microSD memory cards,” SDA President Brian Kumagai was quoted as saying in company’s release.
The memory cards that will display A1 symbol for App Performance Class 1 will meet or exceed performance requirements including Random Read Input-Output access Per Second (IOPS) 1500, Write IOPS of 500, and Sustained Sequential performance of 10MB per second. As of now there are two versions of App Performance symbol and SDA will introduce higher App Performance levels as market need evolves.
The SD Association did not say when SD Specification 5.1 and App Performance Class 1 cards will reach the market.
