We must know the function of Gadgets first. Let's do compare between Dash Cam and Sat Nav here.
Dash Cam is for recording video when you are driving, it requests the microSD card with enough space and high speed, otherwise the video can not proceed smoothly. Then we suggest you take 16gb or above, as it will be big enough to afford varies videos.
Refer to Sat Nav, it is one GPS navigation which will tell you which road is the best one to the destination. It only needs to load one country or city MAP inside, and no needs to record video or photos, then you take 4gb or 8gb card enough.
Here's a list of CNET's picks for Electronic Gadgets with an microSD card slot, and their supported storage capacity:
- Dash Cam: 8GB or Above (16GB and 32GB will be better)
- GPS Navigation: 4GB or above
- Windows Tablet: 8GB to 200GB
- OneTouch Idol 3: 32GB
Once you choose a card capacity, it's associated with its speed. The speed class of your card determines how fast it can write data in your device. When you're shooting with video, or bunches of photos, the faster the better.
Most latest mobile devices will support these speed classes: Class 4/6/10 and UHS-1 Class 10. MicroSDHC cards can be any of these three classes, but Micro SDXC cards are mainly for Class 10 and UHS-1 Class 10.Since maximum speed is not always mentioned on package, here are the minimum speeds and intended purposes of each class:
- Class 10: 10MB/s; burst photos and up to 1080p video files.
