How to Choose the Right microSD Card for Drones

microSD card

Buying the perfect MicroSD card for your drone is a complete headache!

Well, when it comes to size, speed and quality of MicroSD cards, there are lots of differences. And also choosing the best MicroSD card for drone depends on various parameters. Whether you are using First Person View(FPV) or plain line of sight, you will need a card to save all the amazing videos you will capture through the drone.

When you are using FPV headsets with GoPro Hero cameras, you will need high-level capacity MicroSD cards that can be able to hold 4K videos.

Further, most of the MicroSD cards are labeled with the highest reading and writing speed capacities. But testing the cards often fails. Even some popular drone companies like DJI has a list of recommended Micro SD cards for their products, but again finding the fastest card will be frustrating.

One of the most important things to be considered when you are in the market to buy the storage card for the drone is the card’s write speed. For more info, check out this video –

How do you test MicroSD cards?

Usually, to compare with different MicroSD cards, an external USB 3.0 card reader as well as an application like Crystaldiskmark will be used. Then to test the writing or transfer speed of the cards, you can use a video file of 4.1 GB and record the times of transfer of each MicroSD card.

Determining the lowest and fastest MicroSD cards for drones

According to the video that has been provided above, SanDisk Extreme Pro is the fastest card and the slowest is the Kingston Gold MicroSD card. Well, the advertised write speed that has been set for SanDisk Extreme Pro card is 90 MB/S and the tested speed is like 79.66 MB/S.

Whereas the advertised writing speed set for Kingston Gold MicroSD card is 45 MB/S and the tested speed is only 37.7 MB/S. To understand the writing speeds how they work in real time, a video of 4.1 GB is used. The Kingston card took 1 minute 44 seconds to transfer, whereas the SanDisk took only 49 seconds to transfer the same video.

Alternatives for SanDisk Extreme Pro

Even though the SanDisk card is the fastest one, it is a bit costly when comes to its cost. But don’t worry, there are few alternatives you can use. If you can get Verbatim MicroSD card, or Samsung Pro, or Toshiba Exceria Pro, then I will be good enough to store 4k recordings.

The best thing about Samsung and verbatim cards is that they fall in the top 4 MicroSD card list and also they are having the tested writing speed more than that of their advertised one. The advertised writing speed of Samsung is 60 MB/S, and the tested speed is at 65.54 MB/S. Then the advertised writing speed of Verbatim is 45 MB/S, and the tested speed is actually 64.07 MB/S (According to the above video).

If still, you want some other alternatives, then go for Exceria Pro, which is a great option as it’s writing times matches with that of SanDisk.

Compatibility of MicroSD cards other than drones

Well, MicroSD cards are not only be used in drones, but you can use them on your DSLRs. Before we use them on any new device, we’ll format the card. During this procedure, there might be chances for the loss of important files. So, it is recommended to take backups before you proceed with any operations on the card.

If the backup is missing, then the only way you have to recover files from formatted MicroSD card is using Yodot Recovery Software.


Be careful while buying MicroSD cards from E-commerce sites. They are not bluff cards but also may stop working after the purchase. So make sure that buy MicroSD cards only from legit sources. Be smart and stay away from the deals that look too good to be true when you are buying the cards.

Tips to Keep Your Memory Cards Healthy and Safe

Even though memory cards are little in size, they grab a big place in digital photography and requires a great care. But, how can you take care of your memory card and get the best of it? Stop thinking. Here are simple tricks and tips for using as well as caring your memory cards.

SD Cards

Be updated: Camera manufacturers often release firmware updates for cameras. Every now and then this may affect the way your camera communicates with your memory card. So, update your camera in a right way.

Be attentive about low batteries: If your camera goes off during write operation then it affects your card. It causes some issues like card firmware corruption, card errors etc. So, never let your batteries to drain completely. Stop shooting if, you get a warning regarding the low battery. If you want to proceed then replace the battery and go on.

Avoid turning off the camera abruptly: If the camera is still writing data onto the card and you switch it off suddenly then the communication between the card and camera may be interrupted. And this leads to further issues. So, never turn off the camera or eject the memory card while processing.

Don’t fill your card completely: If you fill your card to its full capacity then it makes the camera to not write entire information of the file to the card. It may generate card errors and may corrupt the saved files. So, stop taking pics or shooting videos when your memory card is near to being filled.

Format your memory card in camera: This builds ideal communication between your memory card and the camera. Formatting not just removes the stored data from the card, but it also prevents several issues of your memory card. And, it is suggested to format the card only in camera, not in the computer.

Think before deleting files from the memory card: Don’t delete images, videos, or any file from the memory card via camera, instead ensure that they are on your computer also. Once you copied everything from card to computer. Format it in your camera.

Actually, there are two reasons behind this factor. One is if you don’t have a copy of media files on your computer then you need to go for a recovery procedure and retrieve deleted videos, photos or other files from the memory card if you meet any data loss situations.

Next, deletion of files from your memory card actually shortens the life span of the card. Removing a file means one erase cycle. So, if you delete 100 files it is 100 erase cycles. So, it is not a good idea to delete one file at a time and deleting before you have them in another place. Make a habit of formatting the card once after each upload.

Ensure yours is a fast memory card: Fast memory cards allows the camera to write to faster. Also, they have a speedy read and upload rates. So, you can readily access them on computers. Also, don’t forget to pick good grade cards. Use good card readers and keep your memory cards in covers or card holders. If possible reserve a memory card for one device. Keep multiple cards.

Last words:

After all, there is so much technology filled into these tiny devices, and we shouldn’t take them for granted. You need to give a little attention on these little gadgets and that’s enough to save you from a disastrous circumstance.
