It wasn't too long ago that I would have thought of a dual USB/MicroUSB flash drive as a dream accessory. Now the landscape has changed so quickly, I'm nearly embarrassed that I have yet to buy one. When we first heard about the Leef Bridge Dual-USB/MicroUSB flash drive, the idea was still novel enough that its quirky name wasn't off-putting. Since then the more traditional players have jumped into the ring, with SanDisk and Sony both coming out with their own drives. Now add Kingston's name to that list. Its DataTraveler microDuo is available in 8GB, 16GB, and 32GB doses.


One side of the flash drive can plug into your PC while the other goes into your phone (though not at the same time). This allows you to move files between devices without having to rely on an internet connection, even if your handset doesn't have a microSD card slot. Your phone will still need to run Android 4.0 or higher and have USB OTG support in order to enjoy the gadget, so before you run out to get one, be sure to hit up this compatibility list beforehand.

    For $20 for a 32GB you can't go wrong with this...it can only help...

    • elma

      it may if write speed is like 1-2mb/s. and for the prie i dont think its fast.

      • Cheeseball

        That is the main problem with cheaper/affordable flash drives. There's a chance that the IC on them have horrible write speeds and basic read speeds.

        I want a Patriot USB flash drive with 20 MB/s to 35 MB/s read AND write speeds damn it!

        EDIT: Apparenty Patriot does make one! :D

    The Nexus-4's biggest flaw is the lack of OTG.

      custom kernels FTW

      • Niall Murray

        Even with a custom kernal it still needs an external power source. Unfortunately

    If only the Nexus 4 had USB OTG support like it was supposed to... :/

  • http://www.mscha.nl/ Michael Schaap

    How about the Nexus 5? It's not in the compatibility list, FWIW.

    Guess this is the portable future of USB Flash Disks

  • Stanley Chan

    How about Nexus 7? Mine is 2013 rooted with kk. Will work?

    • Matthew Fry

      Nexus devices don't support OTG out of the box but have the hardware. If you're rooted you just need StickMount (https://play.google.com/store/apps/details?id=eu.chainfire.stickmount&hl=en)

    • taz89

      You can use without root, there's an app called total commander and that has a extention app called usb mount stick.. With those too you can transfer and view files on a USB stick. Lol just saw your rooted so yh Matthew solution is better

  • Sergii Pylypenko

    This one looks smaller than competition. Now, if they finally get rid of that big USB port...

  • Mike Harris

    Either I'm seeing things or the picture in the upper left (next to the headline) reads "64GB" on its label.

  • Cuco

    Meenova MicroSD reader is another option.

    That design reminds me of printers from the 80s for some reason. Anyone else?

    "This allows you to move files between devices without having to rely on an internet connection...." When at any time has getting an internet connection been an issue since the release of 3G cellular like 10 years ago? When was the last time you were at your computer and more than 5 feet from your smart phone? As far as I understand, anyone can move file between their phone and computer with the phone cord, bluetooth, cloud/Internet, local wireless (even with no internet) or any number of sync services. I have been using a smart phone since the first windows phone and not one time ever have I wished there was an easy way to get files transferred. That is because it has always been a built in function. With all the cloud services and 4g cell service, I have not locally stored anything on my phone for about 4 years. I let Dropbox handle it and have access to far more data than I could ever need. All my files are drop box. All my forms are ZipForm all my photos are photo-stream, all my music is iTunes Match, all my movies are cloud. I would need a 70GB flash drive to handle what cloud services do. Why pick and choose what you have on your phone, when you can have it all? So far as no internet connection, that has not been an issue since 2003.

    • David Spivey

      Money. That's the issue. I don't make enough to want to budget for around $45 a month or more for unlimited data. Even if I had unlimited data, it doesn't give me enough bandwidth to enjoy watching a full-definition high quality movie on a trip. Instead, I load up my microsd card before leaving the house with a nice movie, and I have it on my trip. I also store all my pertinent music on my microsd card.

      Just because you live a certain way doesn't mean that others do or should live the way you do. And before you go about trying to class me as a "light" android user simply because I don't have a data package, you should know that I have about 6 android phones, a Nexus 10 tablet, a Nook Color tablet and other android devices here and there. On my Nexus 10 I have over 900 apps installed, and use my tablet daily. My main phone has over 500 apps installed. I am by no means a light user.

      I also don't want to rely on an internet connection because every once in a while, even on the service that has the most coverage, there are always pockets of low network availability. I go out to customers on-site, and need to carry everything with me in case.

    Just wait till usb 4 comes out with the new connector and they have to try to make drives with 3 hook ups :)
