Dash cam requires the right and best micro SD card to be able to improve reliability, thus the best SD card selection is a consideration for dash cam users.

There are many other good alternatives to choose sd card for a dash cam, but we warn to avoid using the Sandisk Ultra card.
Dash cam users and manufacturers report problems with Ultra reliability and speed.
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.

How much space?
For the size of space. 32GB is the sweet spot for good value. That is a 1080P recording of 3-4 hours which is more than enough for most drivers because most drivers only drive around 1-4 hours. Less and you pay more money per gigabyte and only save a few dollars.
| Space | Price (USD) | Price/GB |
|---|---|---|
| 16 GB | Around $6.36 | 0.38 |
| 32 GB | Around $8.97 | 0.31 |
| 64 GB | Around $27.00 | 0.27 |
| 128 GB | Around $25.00 | 0.34 |
All versions of these cards you can buy here and check the current price.
If you can afford it, the 64GB size increases durability. For example, Transcend stated that their 32GB Endurance card lasted 6,000 hours of 1080P video recording before it expired.
What is a Speed Rating?
Class 10 “OR” UHS-I U1 “given 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.
What is Speed Class
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 information are stored.

There are two physical sizes of cards, SD, and microSD. SD cards are used with cameras compared to MicroSD used on cell phones, tablets and most video cameras. In our opinion, microSD is the best and we also recommend this for your dashboard. The reason, with the help of a simple adapter, can make a small microSD compatible as a full-size SD card.
