A Complete Guide to Choosing an SD Card for Your Dash Cam

Do you have a dash cam and are looking for an SD card to go with it? Here’s a comprehensive guide on what to consider when choosing an SD card for your dash cam.

Dash cams have become popular among drivers these days. They're really handy when it comes to recording incidents on the road.

However, the performance of your dash cam depends a lot on its storage. So, it's important to choose the right SD card for your dash cam.

Hence, we'll go over some important considerations you should make when picking an SD card for your dash cam, no matter your experience level.

Key Factors to Consider When Choosing an SD Card

• Capacity
• Write Speed
• Durability
• Temperature Resistance
• Reliability

Key Factors to Consider When Choosing an SD Card

Getting an SD card is not just about storage space; it's about making sure you can capture all your important memories without any issues. Below are some key factors that you should consider while selecting the right SD card:

Key Factors

Capacity

When choosing an SD card for your dash cam, consider the amount of storage space you need based on your driving frequency and desired video quality. When recording in 4K resolution, the storage capacity of your SD card impacts how much footage you can capture:

• 32GB SD card: Approximately 1-2 hours of recording time (~4-8 commutes)
• 64GB SD card: Approximately 2-4 hours of recording time (~8-16 commutes)
• 128GB SD card: Approximately 4-8 hours of recording time (~16-32 commutes)
• 256GB SD card: Approximately 8-16 hours of recording time (~32-64 commutes)

For regular commuting and occasional long trips, a 32GB or 64GB SD card is suitable. However, if you plan to record in high resolution or capture extended footage, consider a 128GB or 256GB card for longer recording durations. So you can choose the capacity that best fits your recording needs and driving frequency. Remember to look at the capacity of the memory card supported by dashcam itself!

• Class 10: Minimum write speed of 10 MB/s
• UHS Speed Class 3 (U3): Minimum write speed of 30 MB/s
  
  Plus, a higher write speed helps prevent dropped frames and ensures that you capture all the important moments without interruption.
  

Write Speed

The second most important thing to consider is the write speed. This determines how quickly the device can record and store data. To ensure smooth recording, especially at higher resolutions, you'll want to look for SD cards with a Class 10 or UHS Speed Class 3 (U3) rating. These cards provide sufficient write speeds for most dash cams.

Durability

Regular SD cards may not withstand the extreme temperatures and constant vibrations of dash cam use, leading to data corruption or premature failure. For reliability:

• High-endurance cards: Designed specifically for dash cams
• Extended write cycles: Ensure long-lasting performance
• Heat resistance: Operate reliably in extreme temperatures
• Shockproof build: Withstand constant vibrations and harsh conditions
• Choose high-endurance SD cards to ensure dependable performance and data integrity.

Temperature Resistance

If you're planning to get a dash cam, make sure to choose an SD card that works well under different weather conditions. Dash cams are exposed to extreme temperatures, so you'll want an SD card that can handle both scorching summers and snowy winters. Therefore, we suggest getting an SD card with wide operating temperature ranges, typically -25°F to 85°F. This will prevent data corruption and ensure that your SD card lasts longer.

Reliability

When it comes to choosing an SD card, it's important to go for a reliable and trustworthy brand. Stick to popular brands that are known for producing durable and high-performance storage solutions. These brands also offer warranty support, so you can get a replacement in case the card fails early. Avoid going for generic or unbranded SD cards, as they may not have the necessary quality control measures and could result in data loss or device malfunction. And, if you’re wondering which brand to go for, let us make it easy for you: Choose 70mai!
