Everything You Want to Know about an SD Card for Your Action Cameras

2019-04-25 | Filed to: #Howto

Have you ever got some camera problems like the freezing issue, poor video playback performance or data loss?

Maybe you are not choosing the right micoSD card!

Theres a pretty good chance that you've found yourself needing to purchase an SD card separately for your action camera. While shopping for a card to use seems trivial, its absolutely crucial to purchase a proper card to help your camera reach full potential. APEMAN action cameras have different SD card class rating requirements. The table below may help you figure out what kind of SD card you should buy.

Camera Model

Speed Class & Storage

SD Card Recommendation

Action Camera A66

Class 10 or above up to 32GB

SanDisk Extreme UHS-I 32GB

Action Camera A70

Action Camera A77

Action Camera A79

Class 10 or above up to 64GB

SanDisk Extreme UHS-I 64GB

Action Camera A80

Action Camera TRAWO

U3 or above up to 128GB

SanDisk Extreme MicroSDXC (UHS 3 / V30) A2 128GB

 Note: Please purchase microSD cards through an official seller.

As you can see, I recommend SanDisk memory cards, but that is not to say they are the only good company out there. Lexar, Samsung or Transcend also make good products. I just want to show that you need to purchase a name-brand memory card. Please remember that you are trusting your images to the card. So it would be worth costing a couple of dollars to get a qualified SD card.

Class 10 vs U3 Card

The higher the resolution your video, the faster speed youll need. Class 10 and U1 cards are capable of recording at up to 10MB/s, well suited for pro-level still cameras shooting full HD 1080P videos. This is a great speed to purchase if youre looking for a balance between compatibility with your current action camera and future usage as well. 4K files are large and require a card with a higher sustainable speed that could be able to write them properly. So in order to record the highest quality 4K video on your TRAWO, we suggest a UHS Speed Class 3 (U3) or above memory card within a capacity between 32GB-128GB. If you like to shoot 4K video or 20MP photos with the TRAWO, youre best off with getting the highest capacity card you can afford.

Actually, a Class 10 or UHS Class 1 SD card may also work well with your TRAWO under the two conditions: 1) You rarely capture videos in 4K resolution; 2) You prefer to capture still images. With a high-resolution sensor, the TRAWO requires a faster card to shoot something that has a lot of detail and motion. U3 cards are quite a bit more expensive than the slower speeds, but if you need them, you really shouldnt risk using anything slower.

Card Speed Test

Its true that there are many fake SD cards on the market. Counterfeit cards correctly report the capacity shown on the packaging, but actually, contain far less. You wont notice this until the camera works weirdly or the card fills up unexpectedly quickly. If you are not sure about whether you are choosing a qualified SD card, some tests may help you to rest assured.

1) Firmware Updates: contact us to get the latest firmware (V. for your TRAWO, and you can test the card speed in its settings. It takes about 30s to check out whether the card speed is OK to run in the camera.

2) Test Tool: download SpeedOut (for Windows) here. As a small and portable software tool, SpeedOut reveals the reading and writing speed of your microSD card. You can simply drop SpeedOut on any location of the hard drive and directly run the executable file.


Know the Video Size

Before you begin your trip, its worth understanding some data sizes for your videos. Storing the footage will vary on the resolution and frame rate youre capturing videos. We collect some data taken from video captured on the TRAWO for 1 second at each of the following settings. 

Video Resolution

Video Size

4K/30fps 3840*2160

7.7MB/s; 462MB/min; 23GB/hr

2.7K/30fps 2704*1520

7.5MB/s; 450MB/min; 22GB/hr

1440P/60fps 1920*1440

6.2MB/s; 372MB/min; 18.5GB/hr

1440P/30fps 1920*1440

6MB/s; 360MB/min; 18GB/hr

1080P/60fps 1920*1080

3.9MB/s; 234MB/min; 11.6GB/hr

1080P/30fps 1920*1080

3.9MB/s; 234MB/min; 11.6GB/hr

720P/120fps 1280*720

3.8MB/s; 228MB/min; 11GB/hr

720P/60fps 1280*720

3.7MB/s; 222MB/min; 11GB/hr

Note that the video size will increase or decrease on the content of the scene being captured, and these values have been rounded up.

Action cameras are designed for capturing your adventure and sharing your moment easily with your family and friends wherever you are. From our market research before, most the users would like to keep their important footage from being overwritten. Thats why the APEMAN action camera cannot cover previous files if the SD card is full in its loop recording mode. If you want to capture the footage of your long-time road trip, our dash cams would be your top choice. Read this blog to know more difference between the action cam and dash cam.

The APEMAN action camera will tell you how many photos you can take before your memory card is full. But this number is only an estimate, so if you happen to take a photo when your card is actually full, you may corrupt the data on the card. To avoid this problem, please make sure to select the suitable resolution and frame rate according to its video size, and leave some extra space on the card.


Formatting Your SD Card

The action camera is great at shooting videos or taking photos, but its not smart at managing the data on your card. Instead of deleting images to save space, you can format your card to make it fresh again once you have downloaded to your computer and backed up the images. Formatting your SD card on a regular basis is the best way to restore the original file structure and avoid redundancy. It also allows the SD card to communicate with the camera in a healthy state.


Speaking of formatting, Ill add more tips for you to keep notes:

1) Format your microSD card before the first use, and format it before its next use once you have inserted the card to another device. Its a good way to make sure the memory card is using a file system the camera recognizes and keep things cleaner on the card.

2) You can format it from its cameras settings menu or on your computer. It would be better to format your card in your camera.

3) Note that formatting the card will erase any content currently saved to the card. So remember to transfer your videos or images to your computer or mobile device in time

Dont Pull Your SD card when the Data is being Written

It’s serious! Pull the microSD card when the camera is working may cause many problems like data loss, or worse, the camera being broken forever. Why not be a little patient and wait a few seconds after its red light on the camera goes off? Be nice to your microSD card, and the camera will thank you.

This tiny MicroSD card seems unassuming that you may take it for granted, but it plays a big role in capturing every moment and keep your videos as well as images safe. Hope this blog helps you solve action camera issues aroused from a microSD card.
