Hi

There are several threads on dash cams and in one of them somewhere, someone was complaining at the cost of Nextbase memory cards for their dash cams. They are ludicrously expensive.

 

As a video cameraman and editor, I have used a lot of memory cards and sometimes manufacturers do use custom memory cards. RED were infamous for this. I have done some tests and can confirm that on a Nextbase 322gw these cards work.  https://www.amazon.co.uk/dp/B09X7BK27V at £12 for a 128GB card it is a no-brainer. 

 

I recommend using the largest card you can fit (128GB in a 322gw)  because flash memory has a finite number of write/erase/re-write cycles. So in a dash-cam the larger the card, the fewer of these cycles there will be.  If you don't record dual files (low and high-res) just the high-res the card will last even longer.

 

The spec for a dash cam memory card should be U3, V30 and A2.   The A2 is a new measure, but it is for continuous write as used in video cameras where the stream has to find random memory blocks to write to on the fly to fill up space The Camera will determine which file to overwrite when the card is full.  See (its accurate, by my god her voice is annoying!)  https://www.kingston.com/unitedkingdom/en/blog/personal-storage/microsd-sd-memory-card-guide   Incidentally, Kingstone are a very good make (I used them in professional video cameras)  and are less expensive than the Sandisk on Amazon.  I only used Amazon as I wanted next day delivery and was ordering other things or I would have gone with Kingston.

 

I have a 64gb Sandisk Ultra A1 and it is fine. In our Skoda I have a Viofo camera, and it is fitted with a Viofo card. These are cheaper than Nextbase cards.

Everyone's cards are less expensive than Nextbase!!! 
SanDisk are a reliable make, as is Kingstone.   Lexar used to be good, now I believe they rent out the name....

However, you do need to make sure you buy from a reliable source. There are many places doing counterfit memory cards. Like insurance, it doesn't matter until you haver a problem, then you need it to work.  You don't want to have a crash and find that the memory card was corrupt.  It is worth checking the contents every couple of months.

Nextbase recommends formatting the card every 2-3 weeks.

That obviously wipes everything on it but assuming you have not had a prang (or want to report merde driving) and therefore don't need any files on the SD card that shouldn't be an issue

The re-formatting frequency will depend on the number of hours you drive and the size of the card.

A 32GB  card will require re-formatting 4 times more often than  128gb CARD.

 

The higher levels of Sandisk cards have auto wear levelling software.  So I can't see the need for re-formatting every 2-3 weeks unless you are a taxi driver with a 32GB card.
