## Questions & Answers

**Q: Will the 1tb card specifically work on the Nintendo switch?**
A: Yes it will.

Also note that the Switch has a maximum write speed of about 100 MB/s. 
Because of this, the "Ultra" and "Extreme" versions of SanDisk cards will have the exact same performance on the Switch since they both exceed the system's maximum read speed, and going over the maximum sees no additional benefit. 

This means you can save a bit of cash by getting the cheaper Ultra version of the microSD instead of the more expensive Extreme. They will both perform identically on the Switch.

**Q: Is this compatible with the garmin 66w dash cam?  says must be formatted fat 32.**
A: It’s actually pretty easy to reformat to fat32 using a free tool called fat32 format. I do it with everything above a 32 fb, since 32gb and below normally come pre-formatted  with fat32.

**Q: Will it work for a dash cam?**
A: It is just like any other micro card and comes with a SD card adapter. Yes it will work.

**Q: Is this memory card compatible with GoPro 7 and up? In reference to the write speed.**
A: Not sure but it works with phones and Nintendo switches
