How to Choose a Micro SD Card for Dash Cam

Before you buy a card, there are things you need to consider, and they are:


If you plan to record a minimum of a whole day’s worth of video, it’s crucial to choose a MicroSD card with enough capacity. You should opt for at least 32GB.

Speed Ratings

In many applications, the speed of the card is essential because it shows the transfer speed of the device. It comes in handy when the card needs to write data at high speeds—especially in the case of a 4K video.

Generally, the SD cards come in different speed classes—which has a lot to do with reading and writing images to and from the SD card.

The speed is in MB/s. For instance. If you buy a Class 4 card, it means that it has a minimum speed of 4MB/s. So, if you go for higher speed ratings, it translates to writing data at a higher speed.

Write and Read speed

The write speed signifies how fast the card can record data from the camera—while the read speed tells you how fast data copies from the card to your computer. Thus, it’s ideal to go for higher write and read speed.


Before you buy an SD card, it’s best to confirm that it’s compatible with your dashcam to avoid technical issues. The SDXC cards are better options compared to the SDHC because they store a lot of photos and videos.


You can opt for SD cards that have a more extended warranty. A lifetime warranty is best.


The price of the SD card should be the last thing to consider after checking other categories. Are you on a tight budget? You can still get a good SD card with remarkable features that’ll keep your dashcam running.

Tips on How to Identify a Fake SD Card

Inspect the product packaging for no seals and inconsistent printing. Plus, the back of the SD card should contain adequate information about the product like a proper UPC.

Inspect the SD card—check if the manufacturer positioned the front label correctly or if the print is easy to peel off. All these signs indicate a fake card.

If you can’t confirm a counterfeit SD card with the tips above, test the card on your computer. Do a quick file copy test that doesn’t include any software—the performance will reveal its authenticity. But, you must use a fast card reader.

Finding a solid sd card for your dashcam is a must. But don’t let that stop you from backing up your data. These days backups are the best way to keep your data safe and we all should do this on a regular basis.

    Just a quick note to anyone buying a Dashcam. Dashcams are very fussy about the type of SD card they use. As an electronic engineer I must stress doing research before your purchase. Contact the manufacture before you purchase. U3 cards get hotter then U1 type cards as of writing this, thus some dashcam models will shutdown due to heat. Most SD cars are not rated for the hot climates. But same are. I am using a Samsung PRO Endurance Micro SDXC Card 64 GB.
