When choosing a dash cam, video quality is a top priority. A 128gb memory card can record up to 12 hours of 1080p video.
To maximize video quality, consider a memory card with a high write speed, such as U3 or V30. This ensures smooth and uninterrupted recording.
Recording in 1080p at 30fps can fill up a 128gb memory card in about 12 hours.
A unique perspective: What Size Sd Card for Dash Cam
Dashcam Memory Card Capacity
A 128 GB SD card can hold a significant amount of dashcam footage, but the actual amount depends on several factors.
The storage capacity of an SD card is measured in gigabytes (GB), with one GB equal to 1,000 megabytes (MB), and one MB equal to 1,000 kilobytes (KB).
Resolution and frame rate play a big role in determining how much footage a 128 GB SD card can hold. For example, footage recorded at 1080p resolution will take up more space than footage recorded at 720p resolution.
Here's a rough estimate of how much footage a 128 GB SD card can hold at different resolutions and frame rates:
It's essential to note that these estimates are based on average file sizes and may vary depending on the specific camera and settings used.
Dashcam Video Quality and Recording
The video quality of your dashcam footage is a crucial factor in determining how much storage space it will require. Higher-quality video will take up more space on your SD card.
Recording in 1080p or 4K resolution requires more storage space than recording in 720p. A dashcam that records at 1080p resolution and 30 frames per second will produce a larger file size than one that records at 720p resolution and 30 frames per second.
Here's a rough estimate of how much dashcam footage a 128 GB SD card can hold, based on different video quality settings:
Video Quality
Video quality is a crucial factor in dashcam footage, and it directly affects the storage space required. Higher-quality video takes up more space on your SD card.

Recording in 1080p or 4K resolution requires more storage space than recording in 720p. This is because higher resolutions produce larger file sizes.
To give you an idea of the impact of video quality on storage space, consider the following:
The actual recording time may vary depending on other factors, such as the compression algorithm used by the dashcam and the length of each recording.
Recording Length
Recording continuously will use up more storage space than recording only when it detects motion or an impact.
A dashcam that records in 1080p resolution at 30 frames per second, with a 5-minute recording loop, can store approximately 14 hours of footage on a 128 GB SD card.
If you have your dashcam set to record continuously, you can expect to fill up the SD card much faster, especially if you're recording in higher resolutions like 1440p or 4K.
For example, a 4K dashcam with a 1-minute recording loop can store only about 45 minutes of footage on a 128 GB SD card.

To give you a better idea, here's a table showing the approximate recording times for different resolutions and recording loop lengths:
Keep in mind that these are rough estimates, and the actual recording time may vary depending on the specific dashcam and settings used.
Dashcam Storage Efficiency
Dashcam storage efficiency is crucial to ensure that you don't miss out on recording key driving incidents due to a lack of available space. A high-capacity 64GB or 128GB microSD card allows you to maximize your dash cam's storage, which means you'll be able to record more hours of footage.
The amount of footage a 128GB SD card can hold depends on several factors, including resolution, frame rate, and compression method used. For example, footage recorded at 1080p resolution at 30 frames per second will take up more space than footage recorded at 720p resolution.
Here's a rough estimate of how much footage a 128GB SD card can hold:
- 1080p resolution at 30 fps: approximately 20 hours of footage
- 1080p resolution at 60 fps: approximately 10 hours of footage
- 720p resolution at 30 fps: approximately 40 hours of footage
- 720p resolution at 60 fps: approximately 20 hours of footage
Factors Affecting Storage Efficiency
Dashcam storage efficiency is crucial for capturing key driving incidents without running out of space. The resolution and frame rate of your dashcam footage significantly impact storage efficiency.
A dashcam that records at 1080p resolution and 30 frames per second will produce a larger file size than one that records at 720p resolution and 30 frames per second.
Compression also affects storage efficiency. Higher compression levels result in smaller file sizes, but may reduce video quality. The level of compression used can vary between different dashcam models and brands.
The actual recording time on a 128 GB SD card may vary depending on factors such as the compression algorithm used by the dashcam and the length of each recording.
Here's a rough estimate of how much footage a 128 GB SD card can hold based on resolution and frame rate:
Dashcam storage efficiency also depends on the Dual Files setting and whether a rear camera is attached. For example, recording at 1080p at 30 fps without a rear camera can store approximately 1,130 minutes of footage on a 128 GB U3 SD card.
Speed Class Ratings
A faster SD card will generally be able to write data more quickly, which means your dashcam can record at a higher bitrate without running into storage issues.
Speed Class Ratings give you insight into how quickly a microSD card can write data, and this is crucial for dash cams that capture video at 4K resolution.
You'll want a card with speed ratings of U3 and V30, which support a minimum sustained write speed of 30MB/s.

Dashcam Footage Management
Managing your dashcam footage is crucial to ensure you have enough storage space and can easily access the footage you need. This is where a 128GB memory card comes in handy, providing ample storage for hours of footage.
Following best practices for dashcam footage management is essential. You should follow some specific tips to manage your dashcam footage effectively.
To avoid running out of storage space, regularly delete old footage that's no longer needed. This will help make room for new recordings and prevent your memory card from becoming full.
Dashcam footage can be a valuable asset in case of an incident or accident. Having easy access to the footage is vital, so it's essential to organize it properly.
