📷 KOOTION 64GB Micro SD Card: High-Speed Class 10 TF Card for Smartphone/Bluetooth Speaker/Drone/Camera/PC/VR Review

None of them are actually 32GB, which is not surprising, but they are not even suitable for recording video from a game camera. Every one of my videos is corrupted. I can't do a full format and SD cards are randomly disconnected when in use. The supplied SD card adapter has its switch set to read-only mode when installed in a computer. I tried fiddling with it a bit and it ended up just falling out leaving the adapter stuck in read-only mode. These are the lower quality SD cards that all other…

I simply decided on the 5-pack because of the price and some positive reviews. I figured that even if they can't handle a full 32GB image (for a Raspberry Pi), they're still cheaper than Samsung's 16GB SD cards. Most of the 32GB images I have will fit, but I've come across a few that don't. The card takes another 247.99MB to burn one of the images I used for testing. If you use these cards for security cameras, phones, etc., they are for you. After writing images to 3 out of 5, the read/write…

These cards seem like pretty good value for money at first glance, but after a few hours in my car DVR both cards failed miserably. constant heavy-duty inherent to DVRs, but these cards also refuse to be formatted with the device. These cards are falsely advertised when the packaging says they are DVR compatible. Not worth the money spent on them if they fail at the crucial moment. My advice: invest a little more money in a branded high endurance dash cam card. I will return them for a refund.

I was skeptical about the nameless brand but seeing the good reviews I decided to give it a try. I used them on a Raspberry Pi 3 and they were a total disappointment. I started by flashing the OS I wanted onto it with Etcher. Each of them failed the checksums on the first pass. Most of them were successful on the second try. Once in the Pi, the OS booted fine, but I could tell they didn't run to the full Class 10 standard (at least they didn't live up to big brand expectations). After about the

I tried three of these cards in three different Linux single board computers. Orange Pi Zero, Orange Pi i96 and Raspberry Pi. All three cards had problems. Slow writing, slow reading and bad writing. The last one is a kicker. Corrupt data after writing. Tests on Raspberry Pi and Orange Pi Zero show problems. Tested again on a much older SANDisk card, no bugs, significantly faster write and read speeds. SANDisk: 4K Random Write Speed: 3163 KB/s : 4K Random Write Speed: 190 KB/s Don't buy it for…
