What are the Types – SD or microSD?
Almost all microSD cards include a full SD adapter so that it will work with your current camera. When you change the camera, you don’t need to buy a new card because most dash cameras use a microSD card.
There are two physical sizes, SD and microSD. We recommend a microSD size even if your camera takes a larger full-size SD card.

What is the best memory size?
At the moment 64GB is the sweet spot for good value. That is a 1080P recording of 5-6 hours which is more than enough for most drivers. Basically, most drivers only drive around 1-4 hours.
| wdt_ID | Recording Speed | 24 Mbps | 17 Mbps |
|---|---|---|---|
| 1 | 32GB | 160 min | 240 min |
| 2 | 64GB | 320 min | 480 min |
| 3 | 128GB | 640 min | 960 min |
What is a Speed Class?
The “10” or “UHS-I U1” class is an optimal choice for a microSD card. A slower card can cause recording problems. See the symbol below for what to look for. Some cards have a rating and it’s okay.
Speed Class Speed class symbols represent the minimum writing speed to SD cards in megabytes per second. Class 10 is the top speed at 10 megabytes/second.
UHS Bus & Class
UHS improves cards by providing a faster interface for compatible devices. Most dash cameras do not use the UHS interface but the UHS card will still function properly.
There are two separate ratings, Bus & Class. The UHS bus is transfer speed and has two levels: UHS-I (50MB / S) and UHS-II (156 or 312 MB / S). UHS Class Speed also has two speeds, minimum writing speed: U1 (10MB / S) and U3 (30MB / S).
Faster SD Speed Will Not Improve Performance
At present, the 1440P is the largest resolution and only requires 1/3 of the maximum transfer speed of the Class 10 card. Only 4K recording with very high bitrate will require an increase to U3 or UHS-II.
Choosing the Right Type of Memory
It is recommended to choose an MLC memory card for long-term reliability. One of the most important characteristics of SD cards, but the least known is the type of NAND. The NAND type describes how the physical cells that store the information are stored.

When searching for a microSD card that best fits your dashboard, there are several specifications that you should consider. Ideally, you can find a microSD with enough capacity to record video all day long (minimum).

Fake SD cards are sold very often. For your own protection, avoid all Chinese-based storefronts like Aliexpress, also avoid eBay. If you buy from Amazon, check to make sure that it is sold by Amazon and not by a third party or “fulfilled by Amazon”. Cheaper companies can become default sellers and sell fake items to you.

Choosing the right SD (Secure Digital) card that will last the longest on the Dash Cam is always confusing because there are so many SD cards available on the market.
Choosing the best SD card for dash cameras is a big question for all dash cam users because some SD cards are known to fail very quickly. Even though you are looking for cards online, and we have tried to sort the 5 best SD cards for your dashboard camera.
