I didnt expect the quality to be so high.

Suggestions for improving the card:
SanDisk 64GB Extreme microSDXC UHS-I Class 10 UHS-I Speed Class 3 V30 A2 160MB/s Memory Card with SD Adapter.

The SANDISK Extreme series is the greatest alternative in my opinion, despite its slightly higher price tag compared to market rivals like Samsung (which, to be fair, doesn't always receive glowing ratings). You should definitely take it if you need stability in 4k recording in action cameras (I took it for SJ7 Start) so as to not sin on the map after. The Extreme Pro series should be chosen only if you are a professional video shooter or you shoot in 8k, or you just have a lot of money)), but not high (at the time of writing the review I bought for 1300r). A manufacturer's lifetime warranty is a strong indicator of quality. CrystalDiskMark is not something I put much stock in because it just displays peak results and not consistent ones.

Pros

The advertised write speed is 60 MB/s (verified at 62.9 MB/s by the h2testw application), while the read speed is advertised as being up to 160 MB/s, which is also extremely nice (but which I was unable to verify because my card reader does not support rates higher than 70 MB/s). Card classification "UHS Class 3 V30 A2" is excellent. cool!

Cons
