What to look for when buying Micro SD Card For Dash Cam? (Buying Guide)

Look out for these things before making an purchase.


Higher the Storage capacity, more hours of recording you can save. Now days, most of dash cam supports up to 4K UHD video quality as well. We recommend you getting at least 64GB of sd card for your dash cam. if you have a micro sd card of 64GB, it can save approx 230 mins of 1080p and 110 mins of 4K UHD recording. When your card gets full, dash cam start to overwrite the existing recording. so make sure to get enough storage card otherwise you might loose your previous recording without getting a chance of making backup of it.

Make sure to format your sd card in FAT32 to make it work properly with dash cam. Also, some dashcams such as blackvue only accepts 64GB size card, as pointed out by some of its users.


If your dashcam supports higher video resolutions then it is best to get a card which has good read and write speed. If write/read speed were good then you can record even in 4K flawlessly without any lag or frame drops. Another important thing to keep in mind, their is a chance that when you test your sd card you won’t get the desired speed. Reason for that is you might be using outdated hardware such as testing in USB 2.0 port or USB 2.0 card reader.

Now, lets take another example, your card write speed is 90MB/s as advertised but your dash cam has limit and can only write at 40MB/s on the SD card, that is where hardware limitations comes in. Even though 40MB/s is still enough for recording in 4K UHD but their is a chance people might think that they got the defective card but in reality it was the old hardware causing speed throttling.

Other Factors

Other factors such as how much warranty sd card has or is it shockproof and temperature proof etc. These factors don’t directly effect the performance of the sd card but they can come in handy when handy. Another example, some cards come with USB card reader but most of the people not going to use it so their is no point of paying extra for that. But for some, card reader might be needed.

Which Micro SD Card is Best For Dash Cam?

All micro sd cards work at same principal and their whole purpose is to store data. If you have average quality dashcam. you going to get almost similar performance no matter what brand you choose. But if you have a good quality cam then get a high speed micro sd card which can handle even Ultra HD recordings.

What Size SD Card Do You Need For a Dash Cam?

It depends in which video quality your dash cam doing recording. If it is a 1080p dash cam than you should at least get a 64GB of sd card for optimal performance considering if you going on a long journey your storage space might run out and you might loose all previous recordings. Otherwise, if recordings getting saved in 480p or 720p than a 32GB card would be enough for your dash cam.

How Long Will a 64GB SD Card Last in A Dash Cam?

SD cards has limited read write cycles. when these cycles ran out card stop working. So, it depends on how often your card is being used by dash cam or how much read write happening on the card. But still your card comes with warranty. You can always claim warranty if sd card don’t work as expected or has short lifespan.

How Much 4K Video Can a 128GB SD Card Hold?

Depends on in which quality you are doing recording! if you doing in 1080p than it will be roughly 400 mins of footage, and at 4K UHD it will be around 150 mins of recording.


Micro SD cards are pretty great and cheap storage solution for dash cams. You can record literally everything on these tiny cards even at 4K UHD. Now, every user has their own needs and requirements.
