A-Data SD card transforms into USB dongle


The A-Data SD Duo Memory card is just a wonderfully simple and simply elegant idea. With the cap on, it's an SD card. Pop the end-cap off, though, and a USB connector is revealed, ready to be popped into any open port and be directly read without any middleman card readers. It comes in capacities of 2GB, 4GB and 8GB, with prices starting at $25.99.

  1. I’ve had a Sandisk card that does this with a surprisingly robust swing-away flap for a few years now and it’s a GREAT idea.

    On our honeymoon across Pa. on Rt.6 it was very easy to offload our daily pictures and videos onto our laptop when we were down for the evening without needing cables and whatnot.

    Class 2 isn’t speedy though for 8GB, although arguably you might not need to offload it as often.
    That appears to be the only down side, aside from the losable cap.

  2. I recently had a co-worker who borrowed my camera for a few minutes attempt to put my USB/SD card into the camera backwards. The end cap got stuck in the camera, and in the process of getting it out, the “read-only” sensor thing in there was damaged, rendering my camera unable to take photos. I can view my photos on the LCD though! *eyeroll*
    I would highly recommend staying away from the kind with the removable end cap. The Sandisk one sounds much better to me.

  3. Thanks for pointing out the SanDisk model, guys. I honestly had no idea there were so many of these.

  4. Neither did I, and I have to admit, it’s a sexy concept. I may have to pick one up before I go to Yellowstone next week.

  5. This is cool, but I have this other one that has a hinge … oh wait, everyone else already mentioned it 🙁

    Just to pile on, the SANDisk hinged USB/SD is definitely one of the best tech purchases I’ve made in a long time – great concept! It makes transferring files between my PDA and desktop a no-brainer (it used to a pain when I had to get files from my SD to a friend’s PC), great for getting large files (i.e Music) on to the SD, or excellent for quick sneakernet file transfers.

    Highly recommended.

  6. Oddly, I just bought something that’s the opposite of this. It’s a micro sd card, with a mini (and normal) sd adapter, which plugs into a normal-looking usb flash drive.

  7. The San Disk one is *remarkable*. Have used it moderately heavily for months now, no damage.

  8. I have the kingston usb microSD card. Put that together with an SD card adapter and you get a fancy set that lets you take pictures on a camera and then transfer them with the dongle without any camera software installed.

  9. I would recommend the ocz trifecta. It has the dreaded cap, but it is a micro sd card in a sd card adapter with a usb connection. I can carry 200gb in a credit card sized case.

  10. Looks like they don’t sell the SanDisk Ultra SD Plus cards anymore. The SanDisk site seems to have taken it off the product lineup and major sites like Amazon and Newegg have largely stopped carrying them. What happened?
