    Hi,.
    I have a Phantom 3 Pro, my question is:
    Is it ok to use ScanDisk Ultra 64GB Micro SD XC 1 on my Phantom for recording 4K movies?
    i have 2 of them and i would like your opinion on it.
    Tks.

    As long as the card is
    Micro SD Max capacity: 64 GB. Class 10 or UHS-1 rating required
    It will be fine.
    No need to pay for the fastest/most expensive cards because the speed is controlled by the Phantom, not the card.

    Meta4, what is the Mb/s i should get? is 30Mb/s fast enough? 4k/30 video for P3P is about 500mb per sec?
    i'm a "future owner" of Phantom 3.. want to get some info of memory card too. Thanks!

    There seems to be a confusion regarding the difference between megabits and megabytes.
    The normal convention is that a megabit is shown as Mb and a megabyte is shown as MB.....and there are 8 bits to a byte.
    Presumably the 30 Mb/s you refer to is the rated card speed, and it should be 30MB/s, which is more than adequate.
    The bit rate of the Phantom when recording 4K is 60Mb/s.

    Thanks for your reply.. i always thought memory card use mbps.. just checked Sandisk official page, you are right, its says MB/s. Lets me double check... so if P3P 4K is 60Mb/s which means I need (60mbps/8), so its 7MB/s is enough?

    just realize official page has the detail.. it says max is 60mb/s.. so any cheap card has min 7MB/s is enough.. :)

    Max Bitrate Of Video Storage

    Phantom 3 Professional
    60 Mbps
    Phantom 3 Advanced
    40 Mbps

    In theory, just about!...but in practice you should use a class 10 card as a minimum (as stated in DJI recommendations). The only advantages in using faster rated cards is that your download times are reduced when copying to your computer for editing.

    I have 2 Lexar 633x 95mbps speed class10 and they work a charm on my P3 and for quick transfer, way faster than my phones sandisk ultra 64gb.

    yeah.. i just want to know the min requirement, then get the one thats most valuable. I guess it hard to get a 10MB/s card.. properly almost same price as a 30MB/s :p

    You know your Ultra is slower than 95MBps, right?

    Lexar is great.. but just want to let you know SanDisk has Extreme Pro that has 95MB/s also. You may want to google some speed/performance test to compare both Micro SD. Remember your camera max write speed and card support will also take place. ;-)

    I have found the Samsung Pro cards are the best value for 4K. I have 2 x 32 gb Samsung Pro cards, and they work great.
