    ......and get a quicker one.

    I bought an iPad mini yesterday, did all the stuff, and took the bird for a flight.Mega pixel delay on the screen so back to the forums. Seems I needed a mini 2. So I rang the store who said I could swap it and pay the difference for a mini 2 - Result

    Having recorded video on the stock card that comes with the P3P yesterday I was unhappy with the result, jittery and staggered - really bad. So while I was changing the iPad I looked for a faster card.

    I ended up buying a Sandisk Extreme Plus microSDXC UHS-1 Card, 64GB, 80MB/s.

    Price on the packet was $199.99 - I asked the guy if he could do better on the card, he said he would do $149.99, the same price as the 32GB card - so I went for it.

    Went to pay for it all, the price on the computer came up as $249.99 - BARGAIN OF THE YEAR

    Well done Daniel at Harvey Norman at Waurn Ponds!!

    A very happy Fish

    Except that a faster, more expensive card will perform just the same.
    Whatever card you put in, it can only take the data as fast as the Phantom's buffer memory will deliver it.

    A card worth $30 will work perfectly well. That's insane money to spend on a card, I'm afraid you got ripped off.

    Ouch! - I paid $30.85 each for 3 of the same cards last Sunday. Sandisk Extreme Plus 64GB 80MB/s (Technically they are "Sandisk Pixtor" which is just the Best Buy relabeled Sandisk Extreme Plus).

    For once DJI did not go cheap on us. The supplied Lexar 16GB UHS-I 633X card is rated at "up to 95MB/s read" which is the maximum speed supported by the SD UHS-I interface. The supplied card is more than fast enough because the highest data rate generated by the camera is 7.5MB/s (4K video encoded at 60Mbps).

    Multiple manufacturers are already producing cards with the UHS-II connector (an additional row of pins on the back of the cards) that are performing at 300MB/s, but only a handful of cameras support them (DJI is not one of them).

    What about photos? I have some RAW files that are ~30 MB.

    That's a fun one. A 5 shot AEB in J+R produces roughly 150MB of data that we would like written as quickly as possible to minimize the time we sit watching the blue circle spin so we can take more photos.

    Sandisk claims write speeds "up to" 90MB/s for the Extreme Pro and 50MB/s for the Extreme Plus. The bus limit for the SD interface is 95MB/s so you're not going to get any faster.

    Second part of the puzzle is the interface on the camera - it has to support UHS-I to get the fastest speeds, and I can't find any documentation on DJI's site that says if it does.

    Step 3 we need to do a real world shoot out where we bench test the P3 shooting 5AEB photos with different cards and record the amount of time it takes for the blue circle to stop spinning and also compare the timestamps on the saved files. If they all come out about the same we'll know the limitations of the internal camera bus and memory.

    If we do find a significant speed difference we'll know which cards perform the best for photographers, who need much higher data rates than video.

    Now I just need a sponsor to provide a Sandisk Extreme Pro card for testing ;)

    The stock card is fine. I haven't had any issues with it. Yeah you got extremely ripped off.

    Best Buy is the scammiest slime when it comes to memory card pricing. At this moment that want $299.99 for the SanDisk Extreme Pro 64GB, but they will price match at $54.99 (B&H, Adorama)

    Or any "accessory" pricing. Don't get me started on the dummies that drop $100 on a super-duper-gold-plated HDMI cable because it says Monster on it.

    As others have noted, the going rate for this card is $149.99. So the store you bought it from was over-charging by $50 and your "deal" was to lower the price to the going rate. If a store can't start at the price that another local national chain store known for selling SD cards... I'd probably stay stay away from them.

    You did not get "Bargain of the year". lol!

    OP is in Australia apparently - don't know about whatever exchange rate, but may have something to do with this . . .

    True.

    I still don't get what he is saying though. The card that comes with the P3 works great.

    Agreed - I'm using a 32 GB version of the supplied card, having no problems at all.

    The cardinal rule with most things (especially tech): if you don't shop around then you will pay more. In the world of smartphones, everyone should be price matching. Those that don't get burned and pay a premium.

    About .76 U.S. to the Australian dollar so he payed about 113 US dollars for a card that can be had to 62 dollars on Amazon.

    He needs to go back to Daniel at Harvey Norman and slap him silly.

    Standard systems engineering. If you want to optimise a system you must spend your money on the bottleneck, not on parts which are not the bottleneck, otherwise all you achieve is a loss of cash.:(
