Best memory card for your DJI drone

What's the best memory card for your DJI drone?

Like most other DJI drone accessories, there isn't one best memory card for all DJI drone owners. In order to choose the best memory card for you, here are some things you'll need to consider:

We'll dive into why these points matter in more detail below.


Understanding the symbols on Micro SD (microSD) memory cards

When purchasing a memory card for your DJI drone, here are the symbols you need to look for on the front of the memory card:

1) Memory Card Size

The size of the memory card is shown in gigabytes (GB). This is the total storage capacity of the memory card.

32GB or 64GB memory cards are large enough for most people's needs. If you're going to be swapping out the memory card after each flight, you could even get away with using a 16GB memory card.

While 128GB memory cards work in most DJI drones, memory cards of this size are usually far larger than what could ever be used. However, they could be useful in scenarios where you won't have an opportunity to remove the photos and videos from the memory card after flying each time (like when on vacation).

Note: If you're doing commercial work or are shooting footage that you would not be able to recapture again at a later time, you should consider swapping out your memory card each time you land. That will allow you to minimize your loss if the memory card somehow becomes corrupt between flights or you lose your drone mid-flight.


2) Memory Card Speed Specs

The speed class symbols show the minimum write speed for the memory card. The speed class will be shown as a C symbol with a number inside (known as the Speed Class) or a U symbol with a number inside (known as the UHS Speed Class).

Memory cards that have a speed class of 10 (a C with a 10 inside) or a UHS speed class of 1 (a U with a 1 inside) are able to write data to the memory card at a speed of at least 10 MB/s. This speed class is a good choice if you're never going to shoot video in 4K or use any of the photo modes that automatically snap photos back-to-back (like the Multiple, AEB, or HDR photo modes).

Memory cards that have a UHS speed class of 3 (a U with a 3 inside) are able to write data to the memory card at a speed of at least 30 MB/s. This speed class is a good choice for shooting video in 4K.

Note: DJI's current line of consumer drones are only able to write data to the memory card at a maximum speed of 120 Mbps (or 15 MB/s). So, you don't need to spend extra money on buying the fastest memory card on the market for the purposes of taking photos and recording video with your drone.


3) Video Speed Class

Some memory cards will also display the video speed class (a V symbol with a number beside it). This symbol can also be used to find the minimum write speed for the memory card. The number designates the write speed in MB/s.

For example, V30 means the memory card writes at a minimum speed of 30 MB/s and V90 means the memory card writes at a minimum speed of 90 MB/s. It basically offers an easier way to find the minimum write speed.


4) Memory Card Read Speed

The read speed determines how quickly data can be copied from the memory card. In general, memory cards with faster write speeds also have faster read speeds. The read speed cannot be found by reading the symbols on the memory card. You'll either need to review the manufacturer's specs or look for speed test results from people who have tested the memory card.

Note: Having a memory card with a fast read speed is not important for the purpose of taking photos and recording video with the drone. However, it will be helpful if you're going to watch video footage and/or review photos straight from the memory card or want to be able to reduce the amount of time it takes to copy/move the photos and videos from the memory card when you're done flying.

Which memory card brand is the best?

Kingston, Lexar, PNY, Samsung, SanDisk, and Transcend are all trusted brands that are known to work well. To be sure you're not buying counterfeit memory cards, make sure you buy from a reputable source like Amazon, a local electronics store (e.g. Best Buy), or other well known companies that sell electronics.

Note: Memory card manufacturer's often offer similar memory cards with different names. For example, Samsung currently sells EVO, EVO Select and EVO Plus memory cards. Some of the names are used to give retailers exclusive rights to sell a specific memory card model. Others are likely for marketing purposes. When choosing a memory card, ignore the names and choose based on the capability of the memory card (using the symbols as described above).

Which memory card is the best price-wise?

The same memory cards are offered by various sellers at a wide range of prices. And those prices are always changing since there are so many people reselling them. You'll likely find the best prices in online marketplaces that have high competition (like on Amazon).

The slower Class 10 memory cards or memory cards with smaller storage capacities are not always the best deal price-wise. For example, there are currently 64GB U3 memory cards that are less expensive than 32GB Class 10 memory cards. So, you might want to also consider purchasing a better memory card if it can be purchased for the same price as the memory card you need right now. Down the road, the better memory card could be used in a newer drone that requires a faster memory card or more storage space.

Here are some of the best deals on memory cards right now:


UHS Speed Class 1 (U1) or Speed Class 10
Good for shooting 1080P video (at less than 120 FPS) and single photos

You can find more deals on U1 Micro SD cards here on Amazon.


UHS Speed Class 3 (U3)
Good for shooting 4K video and photo modes that take multiple photos back-to-back

You can find more deals on U3 Micro SD cards here on Amazon.
