  1. Wow! Issa wawu!

    I hope this one won’t make my phone go crazy sha. This one na overload.

  2. Wow, 400GB microSD card!? This is definitely first of its kind. But one thing I know for sure is that, it’s only meant for big phones alone, people with low range smartphone most not try it on their phones, the size will be too large for them to carry. I hope am right about this? Mister MO

  3. This is terribly terrific.. 400gb.. I haven’t even set my eyes on 200gb.. I love this.. Now we are going to touch the sky

  4. Infact, let’s call this a hard disk please.

    But are most phone processors capable of withstanding an SD card of this capacity?


    U just have to wonder where we would be without the Digital Revolution

  5. Did you see the price?

    Madness is defined as using an SdCard that costs twice the phone you use it on ..

  6. Was asking a techie friend the feasibility of using a laptop that has no hard disk installed AT ALL..

    He said the speed would be the problem.. THE flash drives and SDCards may be matching the hard disks in capacity, but how about the speed?

    If I have a flash drive of half a terabyte (that’s the next logical step), what do I still need a conventional Internal Hard Disk for, with all the crash ability?

  7. Now we’re talking. But the challenge will be in usage. How many phones can carry this?
    On a lighter note tho, because of the price, if an armed robber accosts you and attempts to dispossess you of your phone, you’ll probably roll on the floor crying “Please take the phone and give me my memory card”…
