    I bought Sandisk extreme PRO 64gb micro sd from Amazon sold by Sandisk.
    http://www.amazon.com/gp/product/B00...ilpage_o00_s00


    First of all, the package ripped right off. It was just paper material. I heard genuine one is very hard to tear (It was like that for previous ones I bought)

    But it was sold by Sandisk....So I think it shouldnt be fake.

    I recorded till it says card full and checked file size on computer. It was almost 60gb. so I guess it's genuine 64gb card.


    With previous just Extreme card, I had to record at lowest quality. That's why I bought this card.

    I tried Prores Hq. It plays fine in the camera. I moved it to my computer and it's very choppy. (it's asus netbook. not high speed computer)


    What could be the reason? Computer?

    It plays smooth at Prores LT. that's it. higher, it gets choppy and sound breaks.

    I ran test by using Speedout software. reading and writing speed shows 22mb. this is totally bullshit.

    Did sandisk send fake one? did I do something wrong?

    I bought one from amazon and had similar issues. I returned it. Trying buying from B&H or Adorama. They're pretty cheap now. Could you post a picture of the card? I'd just like to see if it's easily identified as a knock-off.

    If that is actually the card you bought I'd advise you to return it and get this: http://www.amazon.com/SanDisk-Extrem...sk+extreme+pro

    There are no MICRO sd cards on the approved list: https://www.blackmagicdesign.com/au/support/faq/43083

    That said, the choppy playback is likely due to your underpowered computer.

    Yeah sounds like the card reader in the computer is likely usb2. If the camera plays back fine it's probably cool. Shoot raw and you'll know in 2 seconds if the card is fake or not. Good luck.

    I don't think card size affects the speed. it says up to 95mb on the package.

    I inserted the card in iMac and ran disk speed test by black magic design. it gets about 16 mb for writing speed. If I didn't do anything wrong with the test, I am going to raise the hell with amazon or sandisk on monday.

    If it's not on the list, don't use it. Simple.

    1) Micro SD are not on the list

    2) Amazon offers Hassle Free packaging...hence the the sleeve.

    IS there a proper way to test the card? whether it works on bmpcc or not, I can't believe how it gets 16mb speed....
