How to Choose the Best MicroSD Card for Dash Cam?

When selecting a microSD card for your dash cam, it’s essential to consider several factors to ensure that you get the best performance, reliability, and longevity. Dash cams require high-speed storage to record continuous video footage, and they also need to withstand harsh conditions.

1. Capacity: How Much Storage Do You Need?

The storage capacity of a microSD card determines how much footage your dash cam can store before overwriting older files. For dash cams, you generally want a card with sufficient capacity to handle multiple hours of video, especially if you’re recording in high-definition or 4K.

• 128GB to 256GB is ideal for most users, as it allows you to record several hours of high-resolution video.
• For high-end dash cams that record in 4K, larger capacity cards such as 256GB or even 512GB are recommended to ensure continuous recording without overwriting important footage too quickly.

Here’s a table summarizing storage needs based on video resolution:

Resolution	Recording Time per 128GB	Recording Time per 256GB
1080p Full HD	~20 hours	~40 hours
4K UHD	~6 hours	~12 hours

2. Speed: How Fast Does Your Dash Cam Need to Be?

Dash cams require fast read and write speeds to ensure smooth video recording and playback. The speed class of a microSD card is represented by the UHS (Ultra High Speed) and Video Speed Class ratings. For dash cams, it’s essential to choose a card with a high-speed rating to handle continuous, high-resolution video recording.

• UHS-I U3 and V30 cards are the most suitable for dash cams because they support video recording at 30MB/s or higher, which is necessary for 4K video recording.
• Class 10 is the minimum speed requirement for Full HD recording.
• Cards with higher write speeds, like 100MB/s, will offer smoother video capture without buffering or dropped frames.

3. Durability: Can the Card Handle Harsh Conditions?

Since dash cams are often used in cars, which can be exposed to extreme temperatures, vibrations, and other harsh conditions, durability is a key factor when choosing a microSD card.

Look for cards that are:

• Waterproof: Ensures the card continues working even if exposed to moisture.
• Shockproof: Protects against drops or impacts, which is essential for driving.
• Temperature-resistant: Dash cams in cars can experience extreme temperatures, both hot and cold, and a durable card will be able to handle these fluctuations.
• X-ray proof: Useful for those who travel frequently and pass through security checkpoints at airports.

For example, SAMGUNG PRO Endurance and Lexar E-Series cards are designed to withstand extreme temperatures and harsh conditions.

4. Compatibility: Is the Card Compatible with Your Dash Cam?

Before purchasing a microSD card, it’s crucial to check whether your dash cam supports the card’s speed, capacity, and other features. Most modern dash cams support cards up to 256GB or 512GB, but some might be limited to lower capacities or slower speeds.

Ensure that:

• The card’s speed class (UHS-I, U3, V30) matches your dash cam’s recording capabilities.
• The card is compatible with the video resolution your dash cam records (4K or Full HD).
• If your dash cam requires a specific type of adapter or connector, such as a microSD to SD adapter, verify that the card includes one.

5. Reliability: How Long Will the Card Last?

Dash cams require a microSD card that can handle continuous rewriting. A high-endurance card designed for long-term use is important to ensure your card lasts for years of heavy use. Look for cards with high endurance ratings that can withstand thousands of hours of video recording without failure.

• SanDisk High Endurance and SAMSUNG PRO Endurance are specifically built for continuous recording with durability for thousands of hours of footage.

6. Warranty and Support: What Happens If the Card Fails?

Since you rely on your microSD card to store crucial video footage, it’s important to choose a card with a good warranty and customer support. Look for cards with:

• At least a 5-year warranty (such as the SAMSUNG PRO Endurance and Lexar E-Series cards).
• Customer support options for troubleshooting or assistance in case of defects.

7. Price: Balancing Cost and Performance

While it’s tempting to go for the cheapest option, remember that a microSD card for your dash cam is an investment in your security and convenience. High-quality cards from trusted brands like SanDisk, Lexar, and Samsung may cost more upfront, but their durability and performance will save you money in the long run by avoiding failures.

Here’s a quick comparison of some of the best options:
