There have been at least 2 major announcement for new USB 3.0 keys with data transfer speed reaching 100 MB/S and even more up to 300 MB/s
According to representative from Patriot, there are many difficulties for developing USB 3.0 storage keys, similar to the one we all have in our pockets or bags. The main reason is the USB 3.0 controller, a small component that is warming too much for such a small factor device. In order to reduce the amount of heat released, some manufacturers decided to underclock the controller, then add a second controller in order to create a RAID 0 volume to offer expected performance levels without the associated warming effect.
But it seems to be a temporary solution, as having 2 controllers also increase the price of such device. Patriot wants to use the enclosure as a heatsink to offer the native performance levels of USB 3.0. Another option could simply be to wait for USB 3.0 to really kick off, and Intel and Microsoft decided to delay its full adoption/implementation to 2011. At that time we might have controllers with a thinner engraving allowing to better controller heat release.
