Factors to Consider

SD cards can be deceptively similar. It is easy to think that as long as a card fits in your camera, it will be collecting data and storing it safely for you.

Unfortunately, this is a gravely misguided notion. There is a lot of research that goes into picking the right memory card for your dashcam. A few of the factors that you should consider before making your pick are:


Micro SD cards come in a variety of sizes. Some can hold only 2GB of data, while others can hold terabytes of information. You ought to check the capacity of a card before you pick it up.

You do not want to spend your hard-earned money on a 512GB card only to realize later that you didn’t need all that space in the first place.


The next factor you should keep in mind before choosing an SD card is its read and write speeds. This is important since it shows how quickly and easily you can access files on the card using your devices.

Usually, manufacturers indicate the speed of the cards on the surface of the product. There are multiple ways of showing the read and write speeds of a card, the most popular ones being:

  •  Speed Class

This shows the minimum writing speed of a memory card. There are four main classes, namely;

  • Class 2, which has a write speed of at least 2MBps
  • Class 4 with a minimum write speed of 4MBps
  • Class 6 with a speed of 6MBps
  • Class 10 with a speed of at least 10MBps

A Class 10 card will generally have better performance than a Class 2 SD card. However, this is not always the case since the classes indicate a minimum write speed; it is quite possible to find a Class 2 card with a higher maximum write speed than a Class 10 card.

  •  Video Speed Class

This classification also the product’s minimum write speed, but with specific regard to video capturing rate. The classes vary from V6 for cards with a minimum write speed of 6MBps to V90 for cards with a minimum speed of 90MBps.

  • Relative Speed

Sometimes, manufacturers indicate the speed of an SD card relative to the original transfer rate of CDs, which was 150KBps. Therefore, you may come across an SD card with a speed rating of 16x or 4x, which means that it transfers data at a speed 16 or 4 times the speed of the original transfer rate.


You also need to pay close attention to the durability of an SD card before you make your choice. This is especially vital since you will be using the product in your car’s dashboard camera, which is often exposed to a wide variety of conditions.

Some indicators of durability include the card’s ability to withstand vast temperature variations, being waterproof, and being impervious to X-rays.

Video Quality

Another critical factor to consider when deciding which SD card is for dashcams is the quality of the footage that the card can record. Ideally, a dash cam is most helpful when it captures clear images and videos.

If you cannot identify the perpetrators of vandalism, or tell which driver caused an accident, then the camera is not of much help. Be sure to check the video quality that a card supports; the higher the resolution of images, the better.


Before you choose a memory card for your dashboard camera, be sure that it is compatible with your devices. The most pertinent devices in this regard are your camera and laptop.

Unknown to many, SD cards are manufactured for specific hardware. Some cards use formats that are not supported by older laptops and cameras.

To avoid wasting money on a product that will not be compatible with your devices, first, confirm the formats that your devices support and then pick a card from those that are compatible.

Generally, MicroSD cards come in four varieties: MicroSD, MicroSDHC, MicroSDXC, and MicroSDUC. Of these, the MicroSDUC is the most recent type, which means that it is only compatible with the latest devices. Spend some time familiarizing yourself with the different varieties of MicroSD cards to ensure that you pick the best one for you.

Your Needs

MicroSD cards differ vastly in terms of capacity, speed, and video quality.

While you may be tempted to pick the card that has the best specifications, it is better to choose a card that will meet your needs without costing you a small fortune.

For instance, a dashcam requires a memory card with a capacity of 8 to 32GB; anything bigger than that is mostly unnecessary. Some cameras can even rewrite useless files, thus saving you a lot of storage space.

With regards to clarity, you want your card to store images that are clear enough to identify people and things on the road. However, an extremely high level of clarity may not be necessary.

You also want to choose a 4K dash camera card that has a respectable read and write speed. The speed of a card is essential because it determines how easily you can access files. If your card only stores high-quality images, it should also have fast read times to allow you faster access to your data.


Have you ever had a memory card that stopped working for no reason? This is one of the most frustrating experiences, especially if the card in question holds relevant information.

Often, cheaper brands tend to have faulty products that can fail to work at the most inopportune moments.

To avoid this, it is better to spend money on a quality product that will serve you well for a long. Sure, you will have to pay extra for a reputable brand, but the right product is worth every penny you spend on it.

You should also be careful not to buy a counterfeit microSD card. Unfortunately, these fake products are ubiquitous and look deceptively similar to genuine products.

To avoid buying a ripoff, purchase your card from reputable vendors and, even more preferably, from the manufacturers of the dual dash camera. Also, steer clear of vendors who sell high-end brand products at questionably low prices; those are most likely fake products.
