Curious what the definitive micro sd card to use for the P4P is.   I know h.265 requires 100mb/s write speed and i'm having a difficult time finding the card that can for sure do that.

Someone just tell me what to buy,   ahhhh

What do you mean by the definitive card?

"I know h.265 requires 100mb/s write speed and i'm having a difficult time finding the card that can for sure do that."
Are you sure of that? Are you confusing b with B?
The P4P has a max video bitrate of 100 Mbps (12.5 MB/s).
DJI specs say:
Supported SD Cards        Micro SD, Max Capacity: 128GB.
Write speed ≥15MB/s, class 10 or UHS-1 rating required.
Ignore the temptation to go for the biggest, fastest and most expensive card because it won't do anything more for you than lots of cheap cards that meet the modest requirements of the P4pro.

What do you recommend, if you don't mind being asked, thank you

I picked up a few of these last weekend. But they were only $10 a pop.

i use these with my phantom 3 and a whole ton of other devices that use micro sd card:
https://www.amazon.com/Transcend ... /dp/B00CES44EO?th=1
Theyre cheap, theyre fast, and i like them
the 300x model, which are the ones i buy claim to have 45MB/s transfer speeds, but i think thats just their way of saying read speed but still making it sound like that speed also applies to write. from my research the write speed on the card is about 20MB/s which is more than enough for a 100Mbps bitrate, although i haven't tested this myself.
i have only tried this on a p3 with a mere 60Mbps bitrate, and it works just fine, so i cant guarantee its function in a p4, i would trust that it would, and at $10 for 32GB its not much money, especially when compared to a $1500 quadcopter.

I use a bunch of 16GB cards, some from good cheap brands you've never heard of and some big names.
I like to have a lot of different colours to prevent mixing them up .

Any UHS-3 should be more than fast enough.

It only has "Max. Write Speed: 45 MB/s"

supposedly that won't work with h.265's high data rate.

again,  there doesn't seem to be clear info

45mb/s is 360mbps. The P4P can only record at 100mbps..

You are correct in that i'm confusing B for b,   I appreciate the clarification.
I'm still slightly confused because there are so many different specs on so many different cards.

I've just had past experiences with the black magic pocket camera where I thought i had the fastest card only to test out and not be able to shoot raw.

Just want to make sure I can get the 4k 60fps h.265 without dropping any frames

As long as it can record at 100mbps (12.5mb/s) you will be good. UHS-I. If you want to be safe get a write speed of 45mb/s or something UHS-II or III.

FYI, if you plan to record 4K at 100Mb/s on the P4P, you will need a U3 rated micro SD card, otherwise you won't be recording at 100Mb/s. U1 and Class 10 cards are not fast enough.

I put a little guide together for myself. All the information you need to know about SD cards and data rates with the phantom series aircraft can be found below. ____________________________________________________________________________
                                  Transfer Speed Information
1. P3P Max write speed is 60 Mbps (7.5 MBps) at Cinema4K (.45 GB per minute, or 27 GB per hour)
2. P4P Max write speed is 100 Mbps (12.5 MBps) at Cinema4K (.75 GB per minute or 45GB per hour)
4. Mbps (Mega Bits per second transfer speed)
5. MBps (Mega Bytes per second transfer speed)
6. Conversion 8 bits = 1 byte ———So, 8 Mbps = 1 MBps
7. Minimum sustained write speeds. A speed class rating means that the card has been verified to never write slower than the speed of that class.
    1. U3: Minimum 30 MB/s Write
    2. U1: Minimum 10 MB/s Write
    3. Class 10: Minimum 10 MB/s Write
    4. Class 6: Minimum 6 MB/s Write
    5. Class 4: Minimum 4 MB/s Write
    6. V6: Minimum 6 MB/s Write
    7. V10: Minimum 10 MB/s Write
    8. V30: Minimum 30 MB/s Write
    9. V90: Minimum 90 MB/s Write
8. Online Guide https://www.bhphotovideo.com/exp ... cards-money-can-buy
9. Note, a U3 rated SD card is needed for the P4P. https://www.amazon.com/Lexar-Pro ... ds=u3+micro+sd+card

'I've just had past experiences with the black magic pocket camera where I thought i had the fastest card only to test out and not be able to shoot raw.'

Likewise, but cards have moved on in speed since then, and the P4P is still writing at a slower rate than the Pocket did.

'Just want to make sure I can get the 4k 60fps h.265 without dropping any frames'

The Phantom cameras will not drop frames, that can only happen when you are recording CinemaDNG with individual files per frame. The Phantom is recording an MPEG stream, and if it cannot keep up, it simply stops recording.

I just want a link to the card to get so I can click buy,   all the technical stuff is great, but i'm just interested in the takeaway.

Then Buy A Sandisk Extreme Pro card from a reputable dealer, end of story.

BOOM

Thank you!!

P4P Only. I personally went for the SanDisk brand, (Sandisk Extreme PLUS). As of yet, SanDisk has never let me down. You can select from the 16GB, 32GB, 64GB or 128GB. The 128GB is the max that the P4P can handle according to DJI. Prices range from 30.00 to 80.00 USD but worth it. It will support 4k video 60fpc and up to 95MB/s transfer speeds which fully supports the H.265 compression rate. They are designed for drone footage and action cams, just, there a little higher in price than some others. I got the 128GB so I don’t have to cut filming when I’m flying. Here is a link for those interested at Amazon: http://amzn.to/2iqSa3Q

Actually I need some of you to double check this for me... what you have pointed to is a Lexar 1000x UHS-II card - I have this card and it works fine in my P3A. Recently i bought a Lexar 1800x UHS-II card and it wouldn't initiate in my bird... on checking with DJI I find she needs a UHS-I card...

But wait - aren't I using a UHS-II card in the P3A, - so I tried it in the P4P sure enough it wouldn't format or initialize either... Put it back in the P3A - works fine... go figure...

To be on the safe side though I would use a UHS-I card like Sandisk Extreme Plus / Pro or Pony (cheaper)

Not: I too bought a Lexar 1000x UHS-II card 128GB, it doesn't work in my P4P either, when I try to format it in the DJI go app it tells me its a bad card. Works fine in a SD card reader...  Anybody have any ideas?

eBay or Amazon, 64GB or 128 GB UHS-3, Class 10 SDXC, San Disk, Lexar

But why does it work in my P3A and not the newer P4P??? Inquiring minds want to know.

the Lexar 128 GB doesnt work in the P4P, use a Sandisk Extreme Pro or Extreme Plus 128 GB, also the Samsung Pro+ 128 will work.

And what about the recommended Sandisk Extreme cards? (not Pro nor Plus) Any experience with these? They should be sufficiently fast for everything the P4P can do...

Am using the Sony SR64UX2 micro SD card 64 GB. Works like a gem for pictures and 4k 60F as well.

I am using the following Samsung card: https://www.amazon.com/gp/produc ... 2_s00?ie=UTF8&psc=1
What really matters is the write speed, which is 90 MB/s for this particular model.

I have the p4p and I bought this SD card: (San Disk Extreme 64 GB (3)  )   The problem is that the recording stops by it selfs and the video file gets corrupt. I have tried to record in 1080p 60 fps and 4k 60 fps. Both gets the same problem. I went back to the shop and got a replacement, but the same problem apparens.

I have tried:
* format the card from the pc and the DJI-app
* Tried different resolution

I did get a SD card with the drone, this is a Sony 16 GB HC I (3)  class 10.  This works perfectly, but I need more storage.

On DJI´s list SanDisk Extreme is on the supported list. So is there something I missed?

That card should work perfectly, as long as it is a genuine Sandisk card. There are quite a few counterfeit ones around. And when formatting, always do it in the aircraft, because it knows what format to use.

I can tell you from experience that a Sandisk Ultra Plus will not work. Doesn't seem to be able to keep up. Took 2 pictures yesterday & it must have taken 8 seconds to write to the card and reset so that I could take another. The video would stay on maybe 45 seconds max before stopping. Extreme Pro on its way. I compared the memory card that came with the P4P to the one I mistakenly bought. Looks like you need U3 and 90 MB/S transfer rates from what I've been able to figure out.

In the end i chose the SanDisk Extreme 32GB, and it works.
Strange that the 64 doesn't. Good luck and keep us informed.

This is correct, the Ultra series are borderline speed, but the Extreme series are well and truly fast enough.

Samsung Pro+ 128 GB, Sandisk Extreme Pro 64 GB work perfectly

Are you sure that The EXTREME you have is an original one ?
I had a bad experience in the past, with one SanDisk I bought from eBay, an It was a counterfeit, as Geebax said

Does anyone know of any way to test the speed of cards?

easier to just buy a card that is known to work, use the other cards for your camera, gopro etc

In direct answer to the OP's question - the best Micro SD card is the Sandisk Extreme PRO 128gb or 64gb, UHS-II, U3 with write speeds up to 100mb/s and read speeds up to 275mb/s. This is presently the fastest micro SD for the P4P. The UHS-I, V30 version of the same card has speeds of up to 90 and 95mb/s respectively and performs perfectly for half the price. Other cards are compatible but these are the best on the market right now IMO.

From the DJI specs for P4P:

Supported cards | Micro SD
Max Capacity: 128GB
Write speed ≥15MB/s, Class 10 or UHS-1 rating required

The P4P does not support UHS II cards.

UHS II cards have an extra set of pins which are not read by the P4P. UHS II cards will/may work in the P4P but not at advertised speeds.

Best to stay with top quality UHS I cards. (My personal choice - 64 Gig - Lexar 633x or higher or Sandisk Extreme) They are also cheaper.

Let's see if these links can clarify any doubt : www.sdcard.org/consumers/choices/speed_class/index.html
                                                                www.sdcard.org/developers/overview/bus_speed/index.html

Sandisk Extreme and Extreme Plus meet the requirements of P4P, and also the Transcend Ultimate.

Toshiba Exceria MicroSDXC 64 Gb U3 is ok with P4 but it does not work with P4P.
