SAMSUNG PRO Endurance 256GB MicroSDXC Memory Card with Adapter for Dash Cam, Body Cam, and Security Camera, Class 10, U3, V30 (‎MB-MJ256KA/AM)

Seems like these are actual Samsung cards as the packaging has all the legitimate markings (you never know with this stuff). These are V10 rated speed cards, meaning 10 MB/s sequential read and write speeds. I ran these through Crystal Disk Mark on a very fast Dell XPS computer and as can be seen they handily beat the specifications. Interestingly I have a very fast V60 card and these Samsumg cards were faster than the V30 and V60 cards I have on the random 4k Read tests, by 40% and the same as the V60 card on the random 4k Write tests. This should make them very good performers for a Raspberry Pi application.Bottom Line: All in all the Samsung cards easily beat the speed ratings according the Crystal Disk Mark.

There are a lot of great review out there however the main noticeable that is runs cooler. I did a full format on this card and a evo select, yes the evo select has a higher speed but it got extremely hot during formatting so if you touch card it could of burn your hands. However you won't be recording at that speeds in a dash cam however it is good to know if you have a 4k camera you can use this at 60 frames without any additional heat generated. I got an average of 100 MB/s Read and 50MB/s write speed.

I got this card for my 2K dash cam, and it’s been working without any issues. Smooth recording, no errors, and playback looks great.I wouldn’t use it for 4K—some users report problems there—but for 2K or lower, it’s solid. Fast enough, affordable, and from a reliable brand. Happy with it so far.

SAMSUNG PRO Endurance 128GB MicroSDXC Memory Card.Compatable with many things. Has Adapter for Dash Cam, Body Cam, and Security Camera – Class 10, U3, V30 (‎MB-MJ128KA/AM).It can be used in devices that accept 138GB micro SD cards, including phones.For fit, it's a standard micro SD card. It's just a cut above the others for function.I chose this specific card because it is highly rated for durability. It's waterproof and shielded from magnets, x-rays, impact, won't wear out quickly and functions in both cold and hot environments.Sometimes the bargain turns out to be something that costs a bit more.

If you have a Toyota factory dashcam this is the card you need. I tried others like the videos say and they WILL NOT work. I inserted this card and the frustration of listening to the chirping for months was gone. Why did I not listen and why did I wait so long!

Does what it is designed to do, have had no problems with the brand in any past purchase, and have no issues with this one.

Works great
