Knowing that USB flash drives don't really have much going for them other than capacity and good looks, I-O Data made a special line: the U3-DBL Series.
USB 3.0 is a proliferous enough interface. It wouldn't be called universal serial bus otherwise.
Still, it doesn't really have a place in every gadget out there, at least not in its base form.
That is why micro-USB connectors exist, and why some tablets and most phones don't have USB 3.0 full ports – they only have smaller ones.
I-O Data now has a flash drive that can fit in both: the U3-DBL Series. There's a full-size USB 3.0 connector on one end, and a micro-USB port on the other. A slider allows for selection.
The U3-DBL Series comes in 8 GB, 16 GB and 32 GB and works with any desktop, laptop, Macs, even USB OTG tablets and phones.
