Well this is surely a bit of surprising news. The SD Card Association has announced that it is working on a revision to current memory cards that will triple the speeds by 2012. This revision is being made possible because the SD Card Association realized it could add another row of pins lower than the already placed ones. The Association is still debating on how many contacts the second row will have but either way this will allow the speeds of SD cards to triple. Current SD cards have a maxium speed of 104MB/second but the actual transfer rates are slower. The new revision, simply called SD 4.0 for now, will have a maximum speed of 300MB/s which will be blistering fast for any use. This will surely be a welcome boost to users of smartphones and tablets who rely on SD cards for storage.
In addition to not knowing how many contacts to add, the Association does not know exactly what to call the new cards. The current crop of high speed cards are called UHS-I for ultra high-speed bus so it is possible these new cards will be named UHS-II. However that name is still up in the air so it could change over time. This new revision should be finished in the first part of 2011 with products, including microSD cards, hitting retail in 2012.
