I’m sure I saw on here somewhere a list of recommended SD cards, but can’t find it. I’ve had problems with speed with some of the ones I have. Any experiences of good cards for 4K video? Probably 64GB, can’t afford much bigger.
These are the SanDisk 64GB ones I rely upon … and not all that pricey (£13.42, currently)
I have about 6 of the things and use them everywhere … except for the 128gb in my phone.
Other than a couple in things that (a) don’t need that speed and (b) will be in the device until it dies, I’ve actually thrown everything else away so I don’t muddle them.
Hi @ash2020 have a couple of these for the 4k camera on my Typhoon H
SanDisk Extreme 128 GB microSDXC Memory Card
No issues what so ever and at only £19.29, bargain!
Be cautious. Sandisk are very good and thus are often faked by the unscrupulous. On eBay if it is cheap it is probably a fake. Buy from a reputable dealer with a cast-iron returns policy!
Agreed @macspite, the link I’ve posted is the one I used to purchase mine, they are stocked and sold by amazon themselves. Going by the packaging and the SD card its self, I’ve no reason to believe that the pair I received are anything but genuine.
Thanks all. I’ll go for the Sandisk 64GB. I agree, there’s a lot of counterfeit stuff around ATM. I think that’s the one I had in the glug-glug drone.
Got to be Sandisk !, never use anything else !.
Me too, and nearly always amazon (not the market place sellers though)
I just bought a Netac 256GB Micro SD for just under £15.
I’ve taken a short video in 4k 30fps (not in flight) to see if it works.
Can’t see any issues.
If this MicroSD card wasn’t up to the task, what should I have noticed?
I can’t speak for using the DJI App and having problems with an SD card, but I had one mapping mission run through Dronelink failed due to a card failure. The drone simply stopped and put some kind of ‘issue, mission cancelled, continue Y/N?’ message on screen. Carried on the mission, the message came up a couple more times but it was always at the same side of the mapping box so it seemed to be a boundary issue at that point. Got back to the laptop and plumbed the card in, the photos had not been taken beyond the point of the first error message, but it carried on the flying anyway. Grr.
I’m more concerned with the 4K recording capabilities. A U3 V1 card from whichever brand should record in 4K, right?
It’s all about levels of compression and bit rate. “4K” means not a lot, in reality.
I think you are right but I would also say that not all 4k cameras are equal in their demands. Some demand a card capable of recording a higher amount of bits per second than others. So it’s worth while checking both your camera manual (drone if the camera is built in ) and the rated recording speed of the card.
There seem to be loads of iffy cards out there. Small capacity masquerading as large capacity, cards claiming speeds they can’t meet and many fakes of market leaders as well as loads of different odd-name brands. Only buy the best-known brand(s) from a reputable dealer.
And it may seem odd but I prefer to carry a number of lower capacity cards and change to a newly formatted card each flight. If a card does suffer corruption (or gets dropped in long grass or water) the output from only one flight is lost rather than a whole day’s shoot.
U3 V30 is a guaranteed minimum write speed of 30MB/s
It’s more than double the write speed required for an M2P.
The issue with cheaper cards is usually QC and how long they last before failing.
If the drone successfully records video on both branded and non branded cards, there shouldn’t be any difference in the video quality, right?
Nope, video quality would be the same as long as the card meets the U3 V30 minimum speeds as advertised.
A U1 V10 card in an M2P gives a warning.
Test the card using FakeFlashTest.
