Hey thanks for your answer, I think it is about the sd card, but thats strange because mine is quite good from Sandisk.
What feature from sd card should we pay attention in order to have it working flawless in the drone?
The main thing you need to consider is the drone's camera's maximum video bitrate.
The spark's max bitrate is 24Mbps, so your card needs to have a max write-speed of at least that, but probably 2-3x that to support sustained writing at that bitrate. Most SD cards' ratings are a burst-speed, where you need a sustained write-speed over the drone's max bitrate, so making sure you're a few times over that is good. You'll also note that micro SD cards have classes and categories (other than size), those serve as a good general idea if it can record HD or 4k. For HD (Spark), you want a Class 10/A1/UHS-1 card.
A much smaller issue could be the file-system, make sure the SD card is formatted as FAT32, as that's all the Spark supports, this shouldn't be an issue as FAT32 supports up to 2TB, way over your 64GB, but it's a possible issue. If your video recording goes over 4GB, i'm not sure what the Spark will do, so that could be one thing to look at also.
I use http://a.co/iPmmNhZ (note that it's class 10, A1 and UHS-1) and have never had an issue, can record several batteries' worth of flights on one card (though it is good practice to swap a fresh card in at the same time as the battery so you have what you have in case you lose the drone, i got several of that card on Black Friday sale to do just that). |
